常量铝的测定历史上虽然曾应用过重量法及8—羧基喹啉——溴酸盐法或酸碱滴定等法,但目前最主要、最普遍的还是用 EDTA 作为络合剂的络合滴定法。络合滴定测定铝的选择性并不很高,自 Sajo提出以氟化物置换铝—EDTA 络合物后,使络合滴定测定铝的选择性进入新阶段,曾经有专文对络合滴定测定铝及利用 Although the determination of constant aluminum has been used in the history of weight method and 8-carboxyquinoline - bromate method or acid-base titration method, but at present the most important and most commonly used complexing EDTA titration complexation law. Complexometric titration determination of aluminum selectivity is not very high, since Sajo proposed fluoride replacement of aluminum-EDTA complex, the complexation titration determination of the selectivity of aluminum into a new phase, there have been articles on complexometric titration aluminum And use
