Abstract:Thin-layer-iodimetric, Sodium reagent and Gas-chromato-graphy methods were compared to determine methamidosphos. Sodium reagent method was easy and quick for the determination of methamidosphos. While Gas-chromatography was used as contrast test, the methamidosphos wastewater was disposed with activated charcoal cation exchange resin GDX-502 and powdered coal. Optimum treating method was established and the removing ratio of methamidosphos was up to 90% .
Key words:methamidosphos wastewater; thin-layer-iodi-metric; sodium reagent; gas chromatography
