摘要 介绍了31 P核磁共振监测下 ,MOH(M =Li+ ,Na+ ,K+ ,Mg+ ,Ca2 + )滴定不同浓度的H3PW1 2 O4 0(简称PW1 2 )的水解情况 .从中得出由PW1 2 制备PW1 1 M适宜的 The titration of aqueous solutions of heteropoly acid H 3PW 12 O 40 (PW 12 ) with bases MOH(M=Li +,Na +,K +,Mg +,Ca 2+ ) was monitored by 31 P NMR. From this,the most feasible pH condition from PW 12 to PW 11 M can gain.
