摘要
根据凝胶色谱的工作原理,介绍了凝胶色谱在腈纶聚合原液除杂、腈纶纺丝溶剂除铁、腈纶废水预处理等三个方面的应用。实践表明:凝胶色谱即使长期使用也无需用化学试剂再生,使用寿命比离子交换树脂更长,是一种比较理想的溶剂净化手段。
According to gel chromatographic working principle, three kinds of applications of gel chromatography were introduced in polymerization solution purifying, iron removing of spinning solution and waste water treatment. The practice showed chemical regent did not need to regenerate even long time use. Its using lifetime was longer than ionic exchange resin＇s, tt was ideal solvent purification measure.
