Persistent organophosphorus compounds (OPCs) comprise a class of environmental pollutants found in pesticides, that can make their way into surface water supplies. The objectives of this work is to formulate a mechanistic surface mediated models of OPC degradation using LC-MS and computational model data. Development of an efficient catalytic system for OPCs degradation still requires improvements in theory, synthesis, and environmental testing. The results demonstrate: 1) an atomistic mechanistic understanding of organophosphorus degradation chemistry and the role of the catalyst surface chemistries involvement in complete hydrolysis. The atomistic model developed for the model pesticide may be applied to other OPC degradation schemes. Moreover, this research should provide a pathway for large-scale, cost effective remediation pesticides in surface water in agricultural settings. The goal of this research was to develop adequate LC-MS methods, and validate the results.
