ABSTRACT

The study was conducted for the purpose of quantifying lead in various samples of soy-products by micellar spectrophotometry using green chemistry approach. The ligandN2P4HB was synthesized for the purpose with the help of weak acid and is found to be soluble in alcohol, acetone and in chlorinated hydrocarbons such as chloroform. It dissolves in alkaline aqueous media but is practically insoluble in water at pH less than 6. In the presence of surfactants its solubility has been found to be increased significantly. On addition of solution of ligand in presence of surfactants to metal ion solution, colored complex were formed. The local nonpolar microenvironment of the micelles incorporates the non-polar colored complex. Secondly a marked increase in absorption intensity has also been observed. This phenomenon of micellar solubilization with increasing absorption intensity has been used to develop a novel, green, simple, inexpensive and sensitive spectrophotometric method for determination of heavy metal ion in various soy products.
