| Abstract: | For the purpose of treating silver-containing electroplating wastewater and recycling silver, P204 levextrel resin was used to adsorb silver ions. The influences of pH value, temperature, dosage of resin and flow velocity on adsorption effect were studied. The results showed that, the maximum static adsorption quantity could reach 145 mg/g, the optimized adsorption condition was： the pH value was 3, the temperature was 20℃, the flow velocity was 5 BV/h. The proper elute was aqueous ammonia（20% ）, when its volume was 8 BV, and the flow velocity was 5 BV/h, the desorption rate of silver ions could reach 87%. Therefore, the said elute could be used to reclaim silver, and through the treatment by the said process, the effluent water could meet the discharge standard. |
