The separation and reclaiming of various metal ions from acid ,tin, plating ,wastewater, were achieved based on the fact that different metal ions form hydroxide precipitates at different pHs. The influent has a pH of 0.45 and contains Sn 137.3 mg/L, Ni 46.1 mg/L, Fe 11.4 mg/L, and Co 8.6 mg/L. Sn was precipitated as Sn(OH) 2 by adjusting the influent pH to 4.7 with 10% NaOH solution.
