METHOD FOR PURIFYING ALUMINIUM-CONTAINING CHLORIDE SOLUTIONS Russian patent published in 2017 - IPC C01F7/62 C01F7/20 C22B3/10 

Abstract RU 2625470 C1

FIELD: chemistry.

SUBSTANCE: method for purifying aluminium-containing chloride solutions from iron involves, at least, one stage of electrochemical purification of aluminium chloride solutions. Electrochemical purification is carried out at pH of 1.0-3.0, the cathode current density of 0.001-0.150 A/cm2 and the anodic current density of 0.015-0.200 A/cm2. Herewith the process temperature is 20-97°C.

EFFECT: invention allows to increase the purification degree of aluminium-containing chloride solutions from iron, increase the efficiency of the process and reduce consumption of electricity.
