- Abstract
- This study investigated the effect of pH and the presence of coexisting (competitive) anions on the removal of phosphate by titanium mesostructures synthesized using do- or hexadecyltrimethylammonium bromide. To address these research objectives, experiments were conducted (1) under controlled initial pH values (2 to 10); and (2) through injection of nitrate, fluoride, chloride, or sulfate anions into a phosphate solution. Based on the experimental results, an initial of pH of 2 was found to be optimal for use of titanium mesostructures. The presence of fluoride anions in solution significantly decreased the removal efficiency of phosphate removal (3.56% at 3.95 mg/g). However, the addition of nitrate, chloride, and sulfate anions did not affect phosphate removal. Water Environ. Res., 84, 596 (2012).
