On the other hand, when the dose was greater than 4 mg L −1 as Al, the high-purity PACl showed great UV 254-absorbance removal capacity; which was even much greater at high does (e.g., 10 mg L −1). This could be partly attributed to the charge effect where a relative high zeta potential in the test water was achieved by dosing high-purity PACl.
