Abstract
α-Cellulose reacted with TiCl4 was hydrolyzed to obtain a TiO2 coating on the biopolymer surface. CrVI in a concentration range between 10 and 50 ppb was separated from CrIII using a column packed with this material. The presence of other ions such as CuII, MnII, HgII, and FeIII, and the anions VO3- 3, MoO2- 4, PO3- 4, and SO2- 4, did not interfere significantly in the separation process.Keywords
