The invention relates to the technical field of composite materials, and provides a molecular sieve based composite material for purifying phosphorous acid and a method for preparing the same.
本发明涉及一种复合材料技术领域的亚磷酸提纯用分子筛基复合材料及其制备方法。
Phosphor - gypsum is the industrial waste discharged from wet process phosphorous acid production.
磷石膏为湿法生产磷酸排放的工业废渣,因含可溶磷杂质,不能直接使用。
Double-tracer technique was used to determine chlorhydric acid and phosphorous acid in the recovered solution of glycine, N-(canboxymethyl)-N-(phosphoromethyl).
