The electrogeneration of polymeric phosphorus compounds during the anodic oxidation of aqueous solutions of phosphites on a boron-doped diamond electrode has been studied. Although the main oxidation product is orthophosphate, the results indicate the simultaneous generation of short-chain and cyclic compounds containing two and three phosphorus atoms whose evolution has been followed by ion chromatography. The effect on the reaction yield of several operative parameters such as current density, pH, temperature and initial phosphite concentration has been investigated. Consistently with the data presented, a new process for the generation of polymeric phosphates is obtained.

Abstract
The electrogeneration of polymeric phosphorus compounds during the anodic oxidation of aqueous solutions of phosphites on a boron-doped diamond electrode has been studied. Although the main oxidation product is orthophosphate, the results indicate the simultaneous generation of short-chain and cyclic compounds containing two and three phosphorus atoms whose evolution has been followed by ion chromatography. The effect on the reaction yield of several operative parameters such as current density, pH, temperature and initial phosphite concentration has been investigated. Consistently with the data presented, a new process for the generation of polymeric phosphates is obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
