Untersuchungen über die Löslichkeit von Molybdatophosphaten. I. Löslichkeit von Chinoliniummolybdatophosphat
Authors:G Schulze  S Noack
Abstract:Studies on the Solubility of Molybdatophosphates. I. Solubility of Quinolinium Molybdatophosphate The solubility of quinolinium molybdatophosphate was determined radiochemically under conditions of the gravimetric determination of phosphate in hydrochloric acid as well as in nitric acid media. The residue concentration of phosphate variies in the range of 10?8 to 10?9 mol/I. The dependence of the solubility on the reagent concentration and on the concentration of solution components was investigated and discussed variing the pore width of the filters used for separating the precipitate. The accuracy and the precision of the determination of phosphate was not influenced in practice by the solubility.
