Starova T. Spectrophotometric and sorption-spectroscopic determination of the arsenic and phosphorus with heteropolyanions using

The regularities of ion associates (IA) of arsenic and phosphorus reduced heteropolyanions (HPA) with organic dyes (OD) formation and sorption on hard sorbents, their using for the different objects analysis. The study of the conditions of IA sorption on polyurethane foam (PUF) and paper, and motivation of the their using possibility for development of the high sensitive methods of the As(V) and P(V) small contents determination. Spectrophotometry, UV-, IR-spectroscopy, spectroscopy of diffuse reflection. For the first time theoretically using possibility of HPA-OD as analytical forms for preconcentration on PUF and paper is motivated. And the methods of quantitative, visual test and colourmetric determination of the As(V) and P(V) microamount in the different objects are developed . The designed methods complex can use in chemical laboratories for this elements determination in different types of waters and for arsenic determination in minerals, food-stuffs. Theoretical and experimental data are recommended to use for other elements forming HPA determination methods development.
