^aThe main composition of Chaohu lake water was 6.6 mg/L Na(I), 1.7 mg/L K(I), 34 mg/L Ca(II), 7.6 mg/L Mg(II), 3.1 mg/L Cl^–, 12 mg/L SO₄^2–, and 141 mg/L HCO₃^–. The pH values of the suspensions were kept at the initial value by adding negligible amount of NaOH solutions.

^bThe main composition of seawater was 9.8 g/L Na(I), 0.36 g/L K(I), 0.42 g/L Ca(II), 0.93 g/L Mg(II), 17 g/L Cl^–, 2.1 g/L SO₄^2–, and 0.12 g/L HCO₃^–. The pH values of the suspensions were kept at the initial value by adding negligible amount of NaOH solutions.
