【摘要】 <正> 乐果是一种危害较大的环境污染物,常用间接比色法测定其含量,但方法灵敏度低,干扰多,不能直接测定有色、浑混样品。本文报道了根据PAR偶氮试剂在电极上有良好的还原波,参照比色手续将乐更多还原

【Abstract】 A sensitive method for determination of ROGOR based on the chemical reaction of ROGOR to yield azo-compound which is highly responsive to the Oscillopolarography is reported. The detection limit of ROGOR is 0.03μg. ml^-1. The method gives almost the same results as that of the colorimetry.更多还原
