| 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(Ⅲ)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390nm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(20～700μg·L-1)的测定,讨论了测定的灵敏度、选择性和重现性。 |

| Abstract: Tri(8-quinolinolato)aluminum(Ⅲ), 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 20～700μg·L-1. The sensitivity, selectivity and reproducibility of determination are satisfactory. |
