摘要
探讨了原料配比、ｐＨ值对产品焦磷钒酸锆（ＺＶＰＰ）性能的影响。通过Ｘ射线衍射、红外光谱、差热及热重分析和离子交换性能的测定，表明ＺＶＰＰ是一种离子交换容量大（３．９ａｍｍｏｌ／ｇ）、热稳定性和化学稳定性优良的非晶态阳离子交换剂，对Ｒｂ（Ⅰ）、Ｃｓ（Ⅰ）、Ａｇ（Ⅰ）、Ｐｂ（Ⅱ）和ＲＥ（Ⅲ）等离子具有很高的选择性。
A new inorganic ion exchanger-Zr(Ⅳ) vanadopyrophospha (ZVPP) was synthe-sized.The effect of reactant prescription and pH on characteristics of products vVas studied. The physico-chemical properties was investigated by using XRD,IR spectrum and DTA-TGA. The results show that it is a cation exchanger with high ion exchange capacity(3.96 mmol/g),good thermal and chemical stabilities, and also high selectivity for Rb(Ⅰ), Cs(Ⅰ),Ag(Ⅰ),Pb(Ⅱ)and Re(Ⅲ).
