The FORMATION REDUCED HETEROPOLYCOMPLEX 10,MOLYBDO,2,TUNGSTОARSENATE DIAGRAM

– In the article  the data about  establishment  of the optimum conditions of the reduced 10,molybdo,2,tungstoarsenate formation in solution are described. On the basis of the received data the  blue geteropolycomplex formation  diagram  was obtained, the use of that allows quickly to pick up рН solutions of HPК for the set concentration molybdate, and tungstate,ions and can be useful at development of arsenic determination methodologies in different objects that contain the admixtures of molybdenum and tungsten connections, taking into account content of the last.
