【摘要】 Al与 8羟基喹啉反应生成的黄色三（ 8羟基喹啉根）合铝 ?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 40∶ 20∶ 40)为流动相，于 390 nm处测定。拟定了金属配合物的萃取高效液相色谱法，对萃取条件和萃取百分率，色谱分离条件进行了研究。进行了饮用水中总 Al的含量（ 20～ 700μ g· L－ 1）的测定，讨论了测定的灵敏度、选择性和重现性。更多还原

【Abstract】 Tri(8 quinolinolato)aluminum? , 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 UV detector detecting at 390 nm. The mobile phase is a mixture of methyl alcohol and ethyl acetate and water(40∶ 20∶ 20, v/v). As a HPLC method of metal coordinate, the conditions of extraction, extraction efficiency and chromatographic separation conditions have been discussed. The contents of aluminum in drinking water were determined in a range of 20～ 700μ g· L－ 1. The sensitivity, selectivity and reproducibility of determination are satisfactory.更多还原
