| 英文摘要 | With the rapid development of industrialization, removing heavy metal ions of wastewater from the discharge of industrial sewage is a very important topic, because it will severely affect our environment and water ecosystem. in this work, we synthesize two porous adsorbents of zif-8 and zif-67 and further investigate their performance of removing pb2+ and cu2+ from wastewater. results indicate that saturated adsorption capacities of zif-8 and zif-67 for pb2+ reach 1119.80 and 1348.42 mg/g, while they are 454.72 and 617.51 mg/g for cu2+, respectively, which are greatly higher than almost all other porous materials. if we use the excessive adsorbents to treat wastewater, more than 99.4% pb2+ and 97.4% cu2+ can be removed by zif-8 and zif-67 adsorbents. moreover, the two adsorbents also show fast adsorption kinetics, and only need several decade minutes to reach adsorption equilibrium. these features indicate that zif-8 and zif-67 are excellent candidates for removal of heavy metal ions from wastewater. |
