离子色谱法测定降水中有机酸方法的探讨

采用离子色谱法对降水中的有机酸进行测定,实验结果表明,3种有机酸(甲酸、乙酸、草酸)的检出限为0.003,0.004,0.003 mg/L,精密度为1.00%~4.22%,加标回收率为97.9%~102%。

Ion chromatography method is used for the determination of organic acid of precipitation. The results show that:the detection limit of three kinds of organic acid(formic acid,acetic acid and oxalic acid)are of 0.003,0.004,0.003 mg/L separately,the precision is 1.00%~4.22%,and recovery rate of standard addition is 97.9%~102%.
