Application of Electroanalytical Chemistry in Heteropoly Compounds System-Redox Property of Isomor of Silicomolybdic Heteropoly Compound

本文系统地研究了α和β_i-K_5SiM(H_2O)W_(11)O_(39)·nH_2O(略写为α,β_i-SiW_(11)M,M=Al.Ga,i=1.2.3)的氧化还原性质,提出其还原机理,讨论了杂多酸阴离子的结构对其氧化还原性质的影响,确定了极谱第1波半波电位的顺序。

The redox properties of a- and β_i-K_5[SiM(H_2O)W_11O_39 ]·nH2O are systematically studied, and their reaction mechanism has been discussed. The effection of structure on the redox was investigated, the half-wave potential (E_(1/2)) sequence of the first polarographic wave has been compared.
