Studies on the Preparation of Potassium Peroxytungstates from WPTA-H2O2-KOH System

Abstract

Abstract: Three potassium peroxytungstatesK₂W(O₂)₄(PPT-1), K₂W₂O₃(O₂)₄·4H₂O(PPT-2) and K₂W₂O₅(O₂)₂·4H₂O(PPT-3) were prepared by the disaggregation of white powdery tungstic acid with 4%-15% H₂O₂ at room temperature and adjusting pHvalues with potassium hydroxide soluti-ion.PPT-3 is a new compound, its structure has been induced.The peroxytungstates were characterized by IRspectra, UVabsorption spectra, X-ray powdery diffraction and thermogram.It is verified that there exists a new phase of K₂W₂O₇.

Key words: White powdery tungstic acid(WPTA), Hydrogen peroxide, Disaggregation, Potassium peroxytungstates
