聚丙烯酰胺浓度测量方法综述

A REVIEW ON METHODS FOR DETERMING HPAM CONCENTRATION OF AQUEOUS SOLUTIONS

本文综述了１１类测量ＨＰＡＭ浓度的方法，讨论了每一种方法的原理、特点、干扰因素和应用范围。除沉淀方法之外，所有分析方法都受ＨＰＡＭ水解度的影响。ＳＥＣ方法和淀粉－碘化镉方法，特别是采用了流动注射分析技术（ＦＩＡ）的淀粉－碘化镉方法。

Eleven methods for determing HPAM concentration in aqueous solutions are reviewed in this article. These are: SEC, starch triiodide, turbidimetric, fluoispectrophotometric, radioisotopic, viscosity, organic carbon content, UV/visible ionchromatographic, precipitation, calorimetric and ionchromatographic. For every method presented, the principles, advantages and limitations, and interferencing factors are discussed. The determinations of HPAM obtained by all but one (precipitation) methods are based on its hydrolysis degree known. SEC and starch triiodide methods and, especially, starch triiodide method in combination with FIA technique are most suitable to determing HPAM in oil field produced waters.
