25/5/2020, · At concentration 1.09 mg/L, the composite removed completely Cr(III) at 15 min. The removal process depends on ionic strength, initial concentration of pollutants, pH and presence of other anions. The experiment was allowed to run for 4 h and found complete removal of dichromate ions and other anions at their high concentrations (Lv et al. 2011).
