Removal of iron, zinc and magnesium from polluted water samples using thioglycolic modified oil-palm fibre

  Various kinds of agro and wood based fibres can be used to filter both trace and heavy metals from contaminated solutions. The efficacy of thioglycolic acid treated oil-palm fibre was investigated in this study. The result showed maximum absorptions (at pH = 6) of 83.6, 75.6 and 50.8% for Fe++, Zn++ and Mg++ respectively in the Southern Point (SP) samples. Similarly, 79.1, 78.3 and 77.5% for Fe++,...

Some valuable fatty acids exposed from wedge clam Donax cuneatus (Linnaeus)

  The fatty acid composition of the wedge clam Donax cuneatus collected from the sandy beach of Cuddalore (southeast coast of India) was determined. In the analysis, the fatty acid profile by gas chromatography revealed the presence of higher amount of saturated fatty acids (35.28%) than mono (12.71%) and polyunsaturated (11.72%) fatty acids. Among the saturated fatty acids, the stearic acid...

Numerical simulation of the internal vibrations of COOH group in amino-salicylic acids

  Our present work reports the IR spectra of amino substituted salicylic acids recorded by FTIR spectrometer and also simulated theoretically. The simulation was performed using GF matrix and AM1, PM3, DFT method. In this work, the following steps were taken: optimizing the geometry, computing the IR spectra and comparing it with experimental spectra. Assuming Cspoint symmetry, vibrational assignments for the...
