摘要
将一种淀粉基固着剂─低分子量高阳离子度淀粉(LHCS)与传统的聚胺(PA)固着剂分别作用于以树脂酸、脂肪酸组成的溶解与胶体物质(DCS)模型物,通过测定模型物Zeta电位、阳离子需求量等的变化比较了二者的不同作用效果,并通过气质联用仪(GC-MASS)分析模型物各种组分含量的变化,考察LHCS去除DCS的特性。结果表明,LHCS去除脂肪酸、树脂酸的效果优于传统的PA,另外脂肪酸相比于树脂酸更容易被LHCS和PA去除。
A type of starch-based fixing agent-low molecular weight highly cationic starch （LHCS） and a traditional polyamine （PA） fixing agent were used to control dissolved and colloidal substances （DCS） modeled by some kinds of resin acids and fatty acids, the different effects of LHCS and PA on controlling DCS were compared by measuring the Zeta potential of the colloids and the cationic demand of the filtrated liquid, and GC - MASS spec- troscopy was used to investigate the content change of the model compounds. The results showed that compared with the traditional anionic trash catcher PA, the LHCS had significantly better effects in controlling the resin and fatty acids. In addition, fatty acid was much easily to be removed by the LHCS and the PA than the resin acid was.
