Synthesis of inorganic oxide composites with the use of postgalvanic waste solutions of copper(II) sulfate

摘要

Synthesis of inorganic oxide composites with the use of postgalvanic waste solutions of copper(II) sulfateThe study was undertaken to obtain an oxide composite (inorganic colourful pigment) in the method based on the use of postgalvanic waste solution of copper(II) sulfate. The conditions of the process of precipitation of synthetic CuOSiO2 were optimised by checking the effect of the concentration and the volume ratio of the reagents and the temperature on the physico-chemical parameters of the final product. The oxide composite obtained in the optimum conditions was characterised by high refinement of particles and large specific surface area BET of 326 m2/g.
