摘要
介绍了31P核磁共振监测下,MOH(M=Li+,Na+,K+,Mg+,Ca2+)滴定不同浓度的H3PW12O40(简称PW12)的水解情况.从中得出由PW12制备PW11M适宜的pH条件.

Abstract:
The titration of aqueous solutions of heteropoly acid H3PW12O40 (PW12) with bases MOH(M=Li+,Na+,K+Mg+,Ca2+) was monitored by 31P NMR. From this,the most feasible pH condition from PW12 to PW11M can gain.
Key words: PW12; PW11; hydrolysis;
