摘要
本文通过大量试验,确定了密封消解电位滴定法测定水中总有机卤(TOX)的分析流程。该方法装置简单,易于操作,可批量分析。准确度、灵敏度高。其混合水样平均回收率为96.68%,检出限为0.60 mg/L,变异系数为8.3%。适用于饮用水和废水中TOX 的测定。
Numerous experiments have been undertaken to establish the analytical procedure for the determination of total organic halogen(TOX)in water by potentiometric titration dependent on sealed digestion.This method,featured by simple instrument,easy operation,high precision and sensitivity,can be used to carry out a batch analysis of TOX in water or wastewater.For mixed water sample,the average recovery is 96.68%,the limit of detection is 0.60mg/L and the coeffi- cient of variation is 8.3%.
