在40年代以前,由于分析方法未能解决,聚磷酸的应用受到限制。1948年聚磷酸分析首先由Bell用化学法揭开序幕。但这方法只限于短链的聚合物,最高到三聚磷酸,并且很难推广。直到色层分析技术有了发展才使这个问题得到解决。纸上色层分析法和离子交换色层法是当前分离聚磷酸最有效的手段。前者可以分离并定量到十聚磷酸,后者可以分离并定量到十四聚磷酸,对于线状聚磷酸盐采用离子交换树脂Amberlit×E-119,Kcl冼提液(PH=5)可以分离十三聚磷酸盐自六十年代以表,薄层色谱的进展,可以定量分离到八聚磷酸盐。其他分析方法有的能定量二聚、三聚,至多四聚磷酸(盐)。本文着重介绍实用性大的分析方法。
Until the 1940s, the use of polyphosphoric acid was limited due to the failure of analytical methods. Polyphosphate analysis in 1948 by Bell with the chemical first kicked off. However, this method is limited to short-chain polymers up to tripolyphosphoric acid and is difficult to generalize. Until the development of chromatography technology has been made to solve this problem. Paper color chromatography and ion exchange chromatography is currently the most effective means of separation of polyphosphoric acid. The former can be separated and quantified to decametic acid, which can be separated and quantified to tetradecylphosphoric acid. For linear polyphosphates, ten (10) can be separated using Amberlit x E-119 ion exchange resin and Kcl extract (pH = 5) Tripolyphosphate from the sixties to the table, the progress of thin-layer chromatography, octopolyphosphate can be quantitatively isolated. Some other analytical methods can quantify dimerization, trimerization, up to tetrapolyphosphate (salt). This article focuses on practical methods of analysis.
