摘要：

A simple voltammetric method for the determination of phosphonate ion is described. A 12-molybdodiphosphonate complex is formed in a 50mM Mo(VI)-0.5M HCl-70% (v/v) CH3CN system containing phosphonate ion. The yellow heteropolyanion undergoes apparent two-step reductions at a glassy carbon electrode. The voltammetric reduction currents depend linearly on the phosphonate concentration in the range 1 × 10-5-1 × 10-3M. © 1990.
