| Abstract: | Zirconium pillared montmorillonite (Zr-pmnt) with basal spacing of 1. 87 nm was used as adsorbent to study its adsorption technology conditions on Cu2+. Results show that under conditions of Cu2+ concentration of 100 mg/L,0. 1 g Zr-pmnt was added into 50 mL Cu2+ solution and solution pH is 7,constant temperature water bath oscillation at 20 ℃ for 120 min,adsorption saturated capacity of Cu2+on Zr-pmnt is 44. 26 mg/g and Cu2+ removal rate is 88. 52%. |
