Abstract :

The present study aims to assess the impact of rural catchment on the water quality of the Upper Lake and its mitigative measuresUnder the proposed study the surface water drainage flowing through the target villages is being studied and compared with the chemical fertilizer dominant agriculture area .The purpose of this study is to estimate the relative impact of the rural portion of the upper lake catchment to the nutrient and pollution load in the upper lakes. Several physicochemical parameters were analyzed . During the present study nutrient loading was observed at near Goura Bishenkhedi station which is located nearby agriculture field where chemical fertilizers are being used . Higher value of nitrate and phosphate was observed at this station which may be due to joining of nutrient through surface runoff during rainy season.

Abstract :

Bhopal is surrounded with rural areas and is mainly occupied by agriculture land. In the present study an attempt has been made to assess the effect of fertilizers and pesticides on the basis of water quality comparison of different water bodies like Hathaikheda reservoir and Kaliasote Reservoir. Three samples of water collected from each reservoir following the standard procedure (APHA, 1995) on the basis of their importance parameters like pH , Dissolved-Oxygen(DO), Biochemical Oxygen demand (BOD), Chemical Oxygen demand(COD), Nitrate, Phosphate and Potassium were analyzed . Result of these analyzed parameters depicted that some parameters are within the limit as prescribed by ISI & WHO while other are beyond the limit due to the residues of the chemical fertilizer reaching to the hathaikheda Reservoir and kaliasote Reservoir with storm water

Abstract :

 Ground water samples were collected from different locations of Surat city, Gujarat (India). Total 54 sampling stations identified from Surat and their physico-chemical parameters were examined and different indices for corrosion based on data interpreted for the purpose of groundwater usage as drinking as well as industrial usage. Physico-chemicals parameters like pH, Colour, Alkalinity, Hardness, Chloride, Silica, Sulfate, TDS, Odour, COD, SS, Iron, Copper, Chromium, Boron, Temperature, Dissolve Oxygen, Phosphate, Ca Hardness, Mg Hardness, Ca as Ca++, Mg as Mg++ and corrosion indices like Langelier Saturation Index, Ryznar Stability Index, Puckorius Scaling Index and Larson Scold Index were calculated by standard methods. By comparing the results against drinking water quality standards laid by Indian Council of Medical Research (ICMR) and World Health Organization (WHO), it is found that most of the water samples are non-potable for human being due to high concentration of one or the other parameter. Most of the samples have Total Alkalinity, Hardness, Chloride and TDS values much higher than the permissible level stipulated by ICMR and WHO. Even at some places Lenglier Saturation Index value are found higher too. The high values of these parameters may have health implications and therefore these need attention. From different indices it is summarized that many places have corrosion tendency in cooling water so these water should have some pre-treatment before use in cooling water and boiler.

Abstract :

 Some stable solid products are isolated by the ligand substitution reaction between [Rh(PØ3)3X] (X=Cl,Br,I,NCS and SnCl3) and derivatives of 1-phenyl tetrazoline -5-thione without change in oxidation state of Rhodium. The ligand coordinates with its thione tautomerie form and on the basis of elemental analyses, cryoscopic, magnetic, IR, Uv-vis and H NMR Spectral data tentative structure has been assigned for the complexes.

Ceric Ammonium Nitrate (CAN) Mediated Synthetic Transformations: A Green Approach for Pharmaceutical Industry
NEERJA GUPTA and RUBY NAAZ*

Department of Chemistry ANDNNM College,affiliated to CSJM University Kanpur India

Email:-rubynaaz86@yahoo.com

Abstract :

Ceric ammonium nitrate (CAN) has been found to be a green catalyst for the solid phase synthesis of various compounds of pharmaceutical applications. The catalytic approaches are encouraging the design of products and process that reduce or eliminate the use and generation of hazardous substances. CAN has been found to be an efficient catalyst for the solid phase green synthesis of amide derivatives of substituted carboxylic acid with urea in excellent yields under microwave irradiation conditions. This method displays both economic and environmental advantages. High yields are achieved even on a gram scale, while reaction times are considerably shortened.

Keyword : Present paper reveals microwave assisted solid phase synthesis of pharmaceutically important amide derivatives using CAN as catalyst.

Ultrasonic studies on Zn+2-Alizarin complex in aqueous solutions
S. Chidambara vinayagam

Post Graduate and Research Department of Chemistry Presidency College,Chennai India

Abstract :

Ultrasonic velocities (U), densities (r) and viscosities (h) are measured in aqueous solutions of Alizarin in presence of Zn+2 ion at 298 K in the concentration of 2.5 ´ 10-4 M. The interaction between solvent molecules and the Alizarin-Zn+2 ion complexes are observed in the pH range of 3.5-5.5. Acoustical parameters such as adiabatic compressibility (k), free length (Lf), relaxation time (ô), acoustical impedance (z) and solvation number (Sn) values are also calculated. These values indicate complexation of Zn+2 ion with Alizarin at a particular pH.

Keyword : Ultrasonic velocity, viscosity, acoustics, adiabatic compressibility, free length, relaxation time, acoustical impedance, solvation number.

Email:- smridhee2000@yahoo.co.in

Abstract :

The corrosion behavior of Tin coated steel in 0.5M monochloroacetic acid and its inhibition by carbonates and bicarbonates were studied by using change in corrosion potential with time and shift of potential at 35 ± 0.1 ºC. All the data reveal that carbonates and bicarbonates act as an inhibitor in the acid environment. This study may help in screening and in selection of inhibitors.

Abstract :

This paper deals with the corrosion characterization of Al6061- red mud particulate metal matrix composites (MMCs). Al6061 alloy is used as matrix. Commercially available alloy is used. Red mud is the wastage obtained after the removal of aluminium from its ore and contains silica, alumina, titanium dioxide and ferric oxide. Being a ceramic material red mud remains inert and is hardly affected by the corrosion medium. Red mud particles of size 50-80 microns are used as reinforcement. Experiments were conducted to determine the corrosion rate of the samples in sea water procured from Arabian Sea in malpe, Udupi District, Karnataka. MMC's are prepared according to ASTM standards by liquid melt metallurgy technique using vortex method. Composites containing 2, 4, 6% by weight of Red mud and unreinforced matrix were tested using Arabian sea water at room temperature. Specimens are taken in the form of 20mm x 20mm cylinders. They were exposed to sea water for different intervals of time. Corrosion rates of all samples were calculated using the formula 534W/DAT mpy. The results were computerised and simulation curves were obtained. The composite was found to be more corrosive resistant than matrix alloy. In each test the corrosion resistance of both alloy composites was found to decrease with the exposure time. The decrease in the corrosion rates of composites when compared to that of matrix alloy is due to the physical barrier created by Red mud particles.
