Notes	The removal treatment of Cr(VI)- contaminated water by UV photocatalysis was investigated by using synthesized $TiO_2$-coated silica granules in a batch method with an initial Cr(VI) concentration of 5mg $L^(-1)$. In the UV photocatalysis process with 10g of $TiO_2$-coated granules, Cr(VI) concentrations were observed to decrease below the detection limit (<0.05 mg $L^(-1)$) in 300 min in the 10-mL solution, and also gradually decreased with time in the other large volume solutions. The capacity of the UV photocatalysis process to remove Cr(VI) did not fluctuate with the solution volume for samples. The low initial pH of the solution and the addition of chloride ions to the solutions accelerated the removal of Cr(VI) by UV photocatalysis.
