微波消解-电感耦合等离子体质谱法测定生活饮用水中镉含量

Determination of Cadmium in Drinking Water by Microwave Digestion-Inductively Coupled Plasma Mass Spectrometry

采用微波消解法对生活饮用水进行前处理,并用电感耦合等离子体质谱法(ICP-MS)测定镉含量。该消解方法安全高效,节约试剂,污染少,可防止试样中待测元素损失。试验结果可靠,加标回收率为?99%～102%。

The pretreatment of drinking water by microwave digestion and the determination by inductively coupled plasma mass spectrometry (ICP-MS). The digestion method was safe and efficient, saves reagents, reduces pollution, and prevents the loss of elements to be measured in the sample. The test results were reliable, and the recovery of standard addition was 99%~ 102%.
