摘　　要：拟定了金属配合物的萃取 -高效液相色谱法。Al与 8-羟基喹啉反应生成的黄色配合物 ,用氯仿萃取 ,在C8烷基键合固定相上 ,以甲醇 -乙酸乙酯 -水 (体积比 4 0 :2 0 :4 0 )为流动相 ,于波长390nm处测定饮用水中总Al的含量 ( 2 0 -70 0 μg/L)。对萃取条件和萃取百分率 ,色谱分离条件进行了研究 ,讨论了测定的灵敏度、选择性和重现性。The extraction and HPLC method of metal coordinate is provided.A yellow coordinate,produced from reaction of aluminum with 8-Hydroxyquinoline has been extracted with chloroform and determined with HPLC using PC-8 alkyl bonded phase and Uvdetector detecting at the wavelength of 390nm.The mobile phase is a mixture of methyl alcohol and ethyl acetate and water(40:20:40,v/v).The contents of aluminum in drinking water are determined in a range of 20-700ug/L.The conditions of extraction,extraction efficiency and chromatographic separation conditions have been studied and the sensitivity,selectivity and reproducibility of determination have been discussed.
