| Abstract In the present work, a sensitive method for the quantification of Organophosphorus –Pesticides (Malathion and Dimethoate) has been improved. The performance of flame photometric detector (FPD) was evaluated in terms of sensitivity, selectivity and reproducibility. The detector was strongly depending on the absolute and relative flow rates of air and hydrogen gases. The best air-to-fuel ratio for both Malathion and Dimethoate was found to be 0.6 (S mode), the minimum detection limit was found to be 0.0135 mg/l and wide linear dynamic range from 0.04038 to 1212 mg/l. | ||||
