The HG-ASF is adopted to measure the content ofselenium in environmental water and experimental water. Four kinds of cations are measuredusing High Performance Capillary Electrophoresis(HPCE), therefore the accuracy of thisexperiment is ensured.

• 对环境水与实验用水采用湿法消解原子荧光光度法测定硒含量、采用高效毛细管电泳测定了四种阳离子浓度,保证了实验精确性。
