本文应用阴、阳离子交抉树脂交换吸附小分子盐类的特点来纯化大分子磺化产品,并用电导滴定法测量磺基含量,从而计算出产品的磺化度或磺化容量。实测了八种磺化型泥浆处理剂,并与燃烧法定硫的一些结果进行了比较。本法测量标准样相对偏差0.3％,操作方便、迅速。 In this paper, the anion exchange resin cation exchange resin adsorption characteristics of small molecules to purify macromolecular sulfonated products, and measured by conductivity titration sulfonic content to calculate the degree of sulfonation products or sulfonation capacity. Eight sulfonated mud treatment agents were measured and compared with some results from the combustion of the prescribed sulfur. This standard measurement of relative deviation of 0.3% standard, easy to operate, fast.
