1-苯基-3-甲基-4-甲酰基吡唑酮[5](PMBP)在分析化学上已得到广泛应用。有人在研究铌(V)-邻苯二酚(PC)-PMBP有色络合物时,提到钛有类似反应。但迄今尚未见用于测定微量钛。本文主要研究了Ti-PC-PMBP萃取光度法测定微量钛的有关条件。
1-Phenyl-3-methyl-4-formylpyrazolone [5] (PMBP) has been widely used in analytical chemistry. Some people in the study of niobium (C) - pyrocatechol (PC) -PMBP colored complex, mentioned a similar reaction of titanium. But so far it has not been used for the determination of trace titanium. In this paper, Ti-PC-PMBP extraction spectrophotometric determination of trace titanium conditions.
