Analysis of Organochlorine Pesticides in Drinking Water and their Degradation by Synthesized Iron oxide Nanoparticles
This study reports the analysis of drinking water sources of river Krishni catchment, contaminated by organochlorine pesticides. Iron oxide nanoparticles had been synthesized through co-precipitation method and utilized for the degradation of organochlorine pesticides using advanced oxidation processes. The sharp and narrow peaks of X-ray diffraction patterns revealed the crystalline nature of synthesized iron oxide nanoparticles having size less than 100 nm. The nanoparticles were also characterized using TEM, UV-Vis and IR spectral analysis. Liquid-liquid extraction and GC-MS were used for the detection analysis of pesticides. GC-MS technique was used for further quantitative analysis of 19 pesticides. The degradation analysis showed the maximum amount of degradation (up to 98.38 %) of organochlorine pesticides.
