摘要
本文叙述了两性高分子水处理剂在水溶液中有别于一般的阴、阳离子型水处理剂的独特性质,介绍了国内外常见的两性高分子水处理药剂,及其在水处理应用中的独特优势。预测在今后的水处理研究应用中,两性高分子水处理剂将取得突破性进展,而天然改性类两性高分子水处理剂在我国将占有较重要的地位。
The research and development of amphoteric polyelectrolytes for water treatment, which can be classified as synthetic organic macromolecules and modified natural organic macromolecules, are described and evaluated in this paper, including their unique characteristics in aqueous solutions. The polyampholytes find a wide range of uses as floccu-lants, sludge dewatering agents, adsorbents, ion exchangers and chelate agents, and they are superior to traditional electrolytes in water processing. Considering of environmental aspects, much attention has been given to modified natural organic macromolecules in china.
