Remediation of pesticide Endosulfan in solution using gold nanoplates and gamma irradiation a comparative studies using GCMS QP2010PLUS

Gamma irradiation of pesticide 100 ppm Endosulfan in acetonitrile leads to its degradation. The degradation kinetics follow 1st order kinetics that is dose vsconcs follow exponential profile and in acetonitrile/water solution leads to its fast degradation. However even at higher absorbed dose of 45 kGy and above endosulfan does not degrade completely. Hence Au nanoplates solution interaction with endosulfan solution has been tried and final metabolites were analyzed with GC-MS QP2010 PLUS. GC-MS results indicates that Gold nanoplates generated from 300 micromolar solution of AuCl3 by radiolytic reduction of AuCl3, annihilates endosulfan completely and the process is very fast.Thus Au nanoplates interaction is better remediation process than that of Gamma irradiation method.
