| Abstract: | Ni~(2+) in the nickel-containing electroplating wastewater was recovered by chemical precipitation process, and the factors affecting the recovery effect were studied. The optimum process conditions for Ni~(2+) recovery are as follows: reaction temperature 30 ℃, wastewater pH 12-13, 0.1 mol/L NaOH solution dosage 70 mL, sodium polyacrylate used as flocculant, stirring speed 1 250 r/min and stirring time 2 min. The product Ni(OH)_2 can be used as additive in lubricating oil and significantly improve its antifriction and antiwear properties. |
