Abstract :

Organometallic complexes of Ruthenium (II) with 2-mercapto-3-Phenyl-quinazolin-4-one have been prepared and characterized by chemical, spectroscopic (IR, Electronic and 1HNMR), molar conductivity and magnetic susceptibility measurements. The ligand interacts with thione tautomeric form and acts as a monodentate ligand. Octahedral structure is assigned to all ruthenium (II) complexes in which two  molecules are at Trans-disposition.

Abstract :

Some bis-Metal(III) chelates of Ti(III), Cr(III), Co(III) and Ru(III) with 2-mercapto-3-benzyl-quinazolin-4-one have been prepared and characterized using elemental analyses, magnetic susceptibility, conductometric, IR, UV-vis, 1HNMR spectral data. The ligand acts as uni-negative bidentate with Ti(III), Cr(III), Co(III) and Ru(III) but with Sb(III) and Bi(III) acts as neutral monodentate. The proposed tentative structure is consistent with physico-chemical data. The ligand field parameter in electronic spectra have also been calculated.

Abstract :

 A conducting polymer have been as ion carriers for the preparation of potassium ion selective membrane sensor. The electrodes give near nernstian responses in the Linear Concentration range of 1 M to 1x10-2 M with detection limit of the order of 10-2 M. The stable potentiometric signals are obtained with in a short time period of 10 seconds. The effect of pH and the effect medium have been studied found to give a better response. Selectivity coefficient values Kpotpotassium have been evaluated using fixed interference method. Thermodynamic functions such as DGo, DHo and DSo have also been evaluated. The sensors have also been used as indicator electrode in commercially available products.

Abstract :

 The present studies aims to investigate the impact of various chemicals used in agriculture on the water quality of Moksha Dayani Maa Narmada water at various locations. Water samples were collected from various streams pouring water into the Narmada along with water samples at upstream and down stream of river to assess the impact of agriculture wash off from the crop field. The run off of agriculture field contained various undesirable constituents such as acids, alkalies, ammonia, ammonium salts, nitrite, and nitrate, phosphates, pesticides, insecticides etc. All these constituents pollute the stream of river in which they are discharged either in one way or the other. The procedure used to determination of above undesirable constitutes were perform by titrimetricaly, spectrophotometricaly, TLC and chromatography. The Result Confirmed that these stretch of the Narmada River were contaminated with at might affect on human health as well as the whole of the ecosystem. The present studies focused on especially agricultural wash out because 90% of people in Nimar region depending on farming. So the main causes of pollution of the water of the Narmda River are fertilizing material and insecticides and pesticides.

Email:- rameshwarnath.pandey@yahoo.com

Abstract :

Four Co-ordinated Organometallic derivatives of Palladium (0) and Palladium (II) were prepared with triphenyl phosphine and ethylene thiourea. The characterization have been done by chemical, spectroscopic (IR and electronic), molar conductivity and magnetic susceptibility measurements. Triphenyl phosphine and ethylene thiourea behave as neutral monodentate ligands. All Pd0 complexes have tetrahedral structure where as Pd (II) complexes have trans-square planar structure.

A heterogeneous precipitate based potassium membrane ion selective electrode-its preparation and analytical application
J. Thamarai selvi

Department of Chemistry, Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore Tamil Nadu India

Abstract :

 A new potassium ion-selective membrane electrode has been developed based on heterogeneous precipitate and the membrane was development using epoxy resin. An analytically useful potential changes occur in the 1 to10-3M concentration range of KCl. The slope of the linear portion (1x10-1-1x10-3 M) was 55mv/decade. The stable potentiometric signals are obtained with in a short period of 7 seconds. In the presence of 1x10-4M potassium no interference was observed for Na+, Mg2+, Ba2+, Mn2+, ,Ni2+, Cu2+, F- , Cl-, Br-, I-,SO42- ions. The effect of pH and effect of medium have been standardized found to give better response life time of the electrode was approximately 3 months. This electrode has been used for the determination of potassium ion commercially available product.

Solvent Extraction & Quantitative determination of Iron
Kavita Gour

JL Chaturvedi College of Engineering 846 New Nandavan Nagpur India

Abstract :

Various methods of extraction are common and have been investigated in the past few years eg. Spectrophotometric, ion exchange and chromatographic technique. In the present work Fe (II) has been determined from ammonium iron (III) Sulphate by titrimetric and spectrohotometric methods after reduction from a jones redactor using amalgamated zinc as the reluctant in the column. It was determined titrimetrically by titrating against. O.1N KMnO4 solution and spectro-photometrically by formation of a complex with 1, 10 phenanthroline. Effect of change in concentration of HCl solution, different solvents, optimum concentration of iron which can be extracted & effect of foreign ions was studied. It was concluded that maximum extraction of 99.4% was noticed employing diethyl ether as a solvent when 6M HCl was used. The interference caused due to foreign ions on the percentage extraction has been noted.

Abstract :

Low-valent organometallic derivatives of rhodium(I) with 4-amino-5-mercapto-3-substitution-1,2,4-triazole have been isolated from displacement reaction of Rh(Pf3)3Cl with methyl and ethyl substitution of ligand in benzene medium. Oxidation state of metals in these compounds is determined iodometrically. Most probable square planar configuration for Rh(I) have been assigned using various physico-chemical data. Metal-ligand vibrations in the far-infrared spectra of complexes have been reasonably assigned.

Abstract :

The stability constant of mixed ligand complexes of Cd(II) with para aminohippuric acid and some bicarboxylic acids (Malonic Acid, L(+)Tartaric Acid, DLMalic Acid, Maleic Acid and Succinic Acid) have been determined electrochemically. The stepwise formation constants of simple Cd para aminohippuric acid and Cdbicarboxylic acids have been investigated by Deford and Hume's method. Then the mixed ligand complexes of Cd with PAHA and bicarboxylic acids have been studied by the method of Schaap & McMasters. The mixing constant (KM) and stabilization constant (KS) were measured for the comparison of the simple and mixed ligand complexes. The positive value of mixing constants and stabilization constants show that the ternary complexes are more stable than the binary complexes.

1-Butanol solvent treatment to waste lube oil for recycling
N. B. Selukar*

Email:-nbselukar@gmail.com

Abstract :

 Lubricating oils are fluids such as engine oils, gear oils, hydraulic oils, turbine oils, etc. which are used to reduce friction between moving surfaces. They also serve to remove heat from working parts in machinery, remove wear debris, created by moving surfaces and provide a protective layering on the metal surfaces to avoid corrosion. Lubricating oils are prepared by blending different viscosity-based oils with suitable proportion of additives. Base oils are either derived from crude oil or synthetic material manufactured by chemical processes. Re-refining of used lubricating oil is an intelligent option for any country, more so for India, as it would conserve both the natural resources as well as foreign exchange. It would also make us near self-reliant in lube oils. In this paper, an attempt has been made to search an eco-friendly technology for recycling of waste lube oil.
