铬天菁S作为光度法测定铝的试剂已有二十多年的历史.较早是??应用于钢中铝的测定,相继发表的论文不少.特别自六十年代后期“胶束增溶光度法”的出现,以铬天菁S“胶束增溶光度法”测定铝颇受重视.我国七十年代初也对该法进行过研究.许多分析工作者在实验研究的基础上提出一些具有一定特点的实验方案.但是,由于光度法测定铝的适宜pH值正是铝离子水介,聚合以及沉淀 Chromium cyanine S as a photometric method for the determination of aluminum reagent has more than two decades of history is used in the determination of aluminum in the steel, have published a number of papers, especially since the late sixties “micellar increase Solubility method ”appears, the determination of aluminum by chitosan S“ Micellar solubilization spectrophotometry ”is very important.At the beginning of 1970s, this law was also studied.Many analytical workers proposed on the basis of experimental research Some experiments with some characteristics.However, due to the photometric determination of aluminum is the appropriate pH value of aluminum ions, water, polymerization and precipitation
