Abstract:

游离酸度的测量是在经过合适的方法去除水解离子干扰后用碱量滴定法进行的，这些方法包括离子交换、沉淀分离、溶剂萃取和配位剂抑制。配位掩蔽法操作简单、快速、准确、重现性好和实用，特别适用于快速化学分析水解离子干扰的溶液酸度。本文综述了过去几十年文献中报道游离酸度测定时抑制水解离子的配位剂的种类和应用，以及配位剂在酸度测定中的重要性，并结合实际提出了今后的发展前景。
The determination of free acidity is carried out using alkalimetric titration after the removal of the hydrolysable ion by a suitable method such as ion exchange, precipitation or solvent extraction or suppression by complexing the metal ions. The method for masking hydrolysable ions with complexing agent is simple, fast, accurate, reproducible and practical. It is especially applicable to fast chemical analysis for the free acidity measurement of solutions containing hydrolysable metal ions. The present review gives an overview of the literature which reported categories and appli-cations of complexing agent for the suppression of hydrolysis over the past several decades. Im-portance of complexing agent has been given to free acidity measurement in the presence of hy-drolysable metal ions. According to the actual situation, the application status and the developing prospect of complexing agent is put forward.
