摘要
研究了焦磷酸钛-磷钼酸铵新型复合无机离子交换剂制备条件及交换性能.用化学分离、差热分析、X 衍射分析和红外分析测定了交换剂的组成和结构.研究结果表明,由于在2种交换剂表层生成新的化学键而使它们牢固结合在一起,组成一种复合无机离子交换剂.
A new complex inorganic ion exchanger-titaniumpyrophosp- hate-ammonium molybdophosphate is synthesized.This material is investigated by thermoanalytical,electron microscopic,X-ray diffraction and chemical analysis methods.Chemical composition,structure and some related proper- ties of this ion exchanger are reported.At the same time,complex mecharics is studied by infrared spetrometry,and it is found that complex strength is due to producing a new chemical bond.As was known earlier,in parallel with this ebemical bond van der Waals forces are acting on the interface (between the new chemical bond layers) of crystallites of pure inorganic ion exchangers.
