Abstract：To treat wastewater containing Cu²⁺ by NaX molecular sieves powders,NaX molecular sieves were added into the simulated wastewater containing Cu²⁺ for processing.The experimental factors effecting Cu²⁺ removal ratio were studied,and the suitable process conditions were obtained.The results show that under the conditions that the temperature is 25 ℃,pH is about 7 and the exchange time is 20 min,the mass concentration of Cu²⁺in the wastewater reduces from 46 to 1.63 mg/L.The wastewater is up to the national emission standard.The used NaX molecular sieves can be regenerated by NaCl saturated solution and the effect is close to original NaX molecular sieves powders.
