| Abstract: | The treatment of zinc bearing waste water by a soluble dithiocarbamate chelate resin (DTCR) is studied. The effects of the concentration of DTCR, the quantity of FeCI 3, reaction time and pH value of the system on the removal efficiency of zinc are discussed. The experimental results show that when ρ(Zn)=10.6mg/L, pH=9, t =60min, ν(FeCI 3):ν(DTCR)=1.7∶1.0, the content of zinc in the waste water can be decreased to 0.13mg/L, which is less than the national effluent standard of 1.0mg/L. The removal efficiency of zinc reaches to above 98%. The mechanism of removing zinc in the waste water by DTCR is also discussed. |
