Abstract
Studies on the reduction of aqueous solutions of titanium tetrachloride were performed to give titanium trichloride. Experimental data on the anodic dissolution of aluminum in 2.5–10.0 % aqueous solutions of titanium tetrachloride were obtained. It was shown that the reduction of titanium tetrachloride in aqueous solutions increases the pH value and the consumption of the aluminum electrode over the stoichiometric level. It is concluded that it is expedient to use the obtained solutions for wastewater treatment after electrodeposition and effective removal of chromium (VI) compounds at the level of 90–95 % of the stoichiometric amount due to additional effects of coagulation and polycondensation of titanium compounds.
