废水中的Cr6+经H-732苯乙烯型强酸性阳离子树脂交换分离后,浓缩。用电感耦合等离子体质谱法（ICP-MS）检测,该法的线性范围为0～100ng.mL-1、线性相关系数R2=0.9997、检出限为0.02ng.mL-1（3δ）、加标回收率为88%～105%,相对标准偏差≤5%。
The Cr6+ content in wastewater was detected by ICP-MS after it was separated by H-732 type strong acidic cationic exchange resin and concentrated.The results showed that the linear range was 0-100 ng·mL-1,the linear correlation coefficient R2 = 0.9997,the detection limit 0.02 ng·mL-1（3δ）,the average recovery was 88%-105%,and relative standard deviation ≤5%.
