【Abstract】 The synthesis (including its purification and identification) of a new water soluble polymeric-reagent, polyvinyl alcohol condensed p-formylarsenazo (abbreviated as PV-pFASA), is reported for the first time in this paper. As proved by experiments, the analytical properties, esp, its sensitivity and extractivity, of the polymeric reagent are remarkably improved as compared with the non-polymeric species. A preliminary discussion is also given for its application to photometry and to extraction-separation without using organic solvents.更多还原
