Abstract:Sodium sulfide was used in the precipitation treatment of nickel wastewater. The effects of chemicals dosage, reaction time and p H value on the removal rate of the nickel ions in the wastewater were investigated. The results show that the excess ratio of Na2S is 1.1, with stiring 30 min at a rate of about30 r/min, the removal rate of nickel is 95.2%, XRD analysis showes a dense nickel hydroxide precipitate. The hydrogen sulfide produced during the process can be used to treat the wastewater.

Keywords: sodium sulfide; nickel wastewater; nickel precipitation
