表面活性剂在固液界面上的吸附作用是十分重要的课题,为此我们开展了这方面的研究。沸石结构规则,孔大小均匀,具有特殊的吸附性质。近年来由于作为合成洗涤剂助剂的三聚磷酸钠可使水质富营养化,故国内外都在研究洗涤剂的低磷化措施。4A沸石具有成本低、无毒性等优点,现已作为洗涤剂助剂使用。4A沸石可使水质软化,其作用是4A沸石中的Na~+为硬水中的ca~(2+)、Mg~(2+)等交换。因此,研究大部分的Na~+已被Ca~(2+)交换而形成的5A沸石自水溶液中吸附表面活性剂就具有一定的实际意义.
The adsorption of surfactant on the solid-liquid interface is a very important issue, for which we conducted this research. Zeolite structure rules, uniform pore size, with special adsorption properties. In recent years, as a synthetic detergent additives sodium tripolyphosphate water eutrophication, it is at home and abroad are studying the low-phosphate detergent measures. 4A zeolite with low cost, non-toxic, etc., is now used as a detergent builder. 4A zeolite can soften the water quality, the role of 4A zeolite Na ~ + hard water ca ~ (2 +), Mg ~ (2+) exchange. Therefore, the study of most of Na ~ + has been Ca ~ (2 +) exchange formed 5A zeolite adsorbed surfactant from aqueous solution has some practical significance.
