Abstract :

A simple rapid new spectrophotometric method has been developed for the determination of cadmium at trace level using 1-(2- pyridylazo)-2-naphthol (PAN) in cationic micellar solution of cetyltrimethyl ammonium bromide (CTAB). The present method with the use of micellar system replaces the previous solvent extraction method, which reduces the cost and toxicity, while enhancing the sensitivity, selectivity and the molar absorptivity. The average molar absorption coefficient and Sandell’s sensitivity was found 1.59 104 􀀀Lmol-1cm-1 and 7.0 ng 􀀀 cm-2 at λ max 544.86 nm. Beer’s law linear calibration graph was obtained over the concentration range 0.12-4.0 􀀀 μg 􀀀 mL-1, the stoichiometric composition of the chelate was 1:2 (Cd: PAN). The method was applied for the determination of cadmium from real samples.

Chemical Laboratories, Sarojini Naidu Government Girls P.G. Autonomous College, Shivaji Nagar, Bhopal  (INDIA)

Abstract :

Reaction of Ampicillin and Alanine with certain biologically active metal ions, in binary and ternary systems have been traced conductometrically and spectrophotometrically. Formation of M:Ala:Amp. 1:1 and 1:2 complexes and M:Ala:Amp 1:1:1 complexes with metal:Alanine:Ampicillin in1:1:1 molar ratio have been ascertained on the basis of analytical data adn physiochemical properties.The results of metal bridged drug receptor complex is formed during antibiotic activity of drug.

Abstract :

The present study deals with the investigation related to physico-chemical characteristics of water of the Surya kund, a religious pond located in Gaya Town of Bihar, India. Besides temperature, 17 other limnological parameters have been studied following standard methods for sampling at 3 different sites of the pond. The physicochemical parameters like transparency, pH, DO, BOD, COD, free CO2, total alkalinity, conductivity, CaCO3, TSS, TDS, Chloride, Ammonia, Nitrite, Nitrate, Phosphate, etc. have shown distinct temporal and seasonal variations during the study period of the pond. Higher nutrient contents like nitrate and phosphate were observed to be present in the pond. The results of water transparency, dissolved oxygen, BOD, COD, CO2, total alkalinity, conductivity, CaCO3, hardness, TSS, nitrate and phosphate were correlated with various physico-chemical parameters in the pond. The physico-chemical quality of water of the pond revealed the poor water quality standards. These specific characteristics indicated towards the contamination of water due to a number of factors including local resident’s sewerage outlet and leaving behind of the worship materials like flowers, garlands, disposal of incomplete burnt worship (hawan) materials, fruits as offerings, leafs etc. as organic matter in the pond. The two years (February, 2012 - January, 2014) of survey reflects higher degree of pollution in the pond.

Studies on Chemical Pollution of Soil by Effluent Released from Cane Sugar Factory
DASHARATH DOMAL

Principal Kakatiya Institute of Technology and Science for Women Nizamabad-503003 A.P. (INDIA)

Abstract :

The Present work is taken up to investigate the possible influence of cane sugar factory effluent on the physico-chemical properties and heavy metal contamination of Agricultural land. The effluent sample is collected and analyzed. The Soil samples are collected at sugar factory effluent irrigated area at the depth of 0-15, 15-30, and 30- 45cm and the five samples are collected at the depth of 0-15cm at different distances from effluent channel to study the lateral seepage of effluent. These samples are analyzed by standard methods and the heavy metal concentration is estimated by using ICP – AES.

Abstract :

In this investigation, leaching of aluminum from aluminum foil in different food samples (red meats and chicken) was studied. The effect of cooking treatments (temperature and time of cooking) on aluminum contents of food samples baked in aluminum foil was evaluated. Cooking increased the aluminum concentration in both samples under investigation. The highest increase was in chicken sample baked for 20 min at 250C . It was also found that the acidic content of chicken sample in addition to the cooking process affected the migration of aluminum. Excessive consumption of aluminum from leaching aluminum foil has an extreme health risk effects. Aluminum foil may be used for packing but not for cooking.

Abstract :

Some bi-coordinated four membered ring chelates of composition ML [M = Cu(1)/Hg(1); LH = 1-benzyl tetrazoline-5-thione]
have been prepared and invested using elemental analysis, magnetic, IR, UV-vis and 'H NMR spectral data. The thioamide ligand acts as mono negative bidentate (N,S) and no disproportionation of Hg(1) and Cu(1) occurs during complex formation.
