新型环保清洗剂中的无磷清洗剂
如今盛行的清洗剂中，一直都以含磷的聚合物为主，例如用得对比多的三聚磷酸钠，既有软化水的效果，也有乳化效果等，且本钱还对比低。可是由于过量的磷对水体有严峻的污染，简单导致湖水等的富营养化而损坏水资源的生态平衡，现已被列为限制运用的化学品。在这种状况之下，开发无磷的清洗剂就成为了重要的课题。选用不含任何磷元素的化学品制成无磷的清洗剂即是无磷清洗剂。
当前能够用来制作无磷清洗剂的有机酸主要是有机羧酸，而有机羧酸又能够分为以下三大类可供选用。
(1)氨基羧酸类
比方氨三乙酸钠(NTA)、乙二胺四乙酸钠(EDTA)、羟乙基乙二胺三乙酸钠(HEDTA)、二亚乙基三胺五乙酸钠(DTPA)等,；
(2)羟基羧酸类
如乳酸钠、酒石酸钠、乙醇酸钠、柠檬酸三钠、葡萄糖酸钠等；
(3)二元羟酸类
如草酸钠、马来酸钠、丙二酸钠、琥珀酸钠等。
从当前的状况看，选用柠檬酸三钠对比可行，无论是从性能上仍是从本钱方面的思考，其都与三聚磷酸钠有适当的才能,。
