Description
Summary:The kinetics of sorption of scandium and main impurities (iron, titanium, zirconium, aluminum and thorium) from hydrolysis sulfuric acid from titanium dioxide production by phosphorus-containing cation exchanger Purolite D5041 was investigated. The results of experiments by the limited-volume method and method of interruption showed that sorption occurred in a mixed-diffusion mode for all studied elements. Experimental data can be adequately described by a pseudo-second order model equation. This indicates that sorption was accompanied by intramolecular interaction of sorbed substances.
