重金属污染已严重威胁环境和人类健康。本文研究陶瓷膜错流扰动对Zr-MOFs吸附重金属Cu(Ⅱ)的促进作用。间歇烧杯吸附表明,Zr-MOFs能很好地吸附Cu(Ⅱ),pH为6、温度40℃时,最大吸附量达61.4mg·g~(-1)。利用陶瓷膜连续错流扰动促进Zr-MOFs对Cu(Ⅱ)的吸附,结果表明相同温度下,50nm膜错流扰动时Cu(Ⅱ)吸附量可达809.6mg·g~(-1)。可见,陶瓷膜错流扰动可显著提高Zr-MOFs对重金属Cu(Ⅱ)的吸附量。
Heavy metal pollution has posed a serious threat to the environment and human health. In this paper, the promotion of Zr (superscript 2 +) on the adsorption of heavy metal Cu (Ⅱ) by ceramic membrane cross-flow perturbation was studied. Intermittent beaker adsorption shows that Zr-MOFs can adsorb Cu (Ⅱ) well, and the maximum adsorption capacity is 61.4mg · g -1 at 40 ℃. The adsorption of Cu (Ⅱ) by Zr-MOFs was promoted by continuous cross-current disturbance of ceramic membrane. The results showed that the adsorption capacity of Cu (Ⅱ) reached 809.6mg · g -1 at the same temperature. Visible, ceramic membrane cross-flow disturbance can significantly increase the Zr-MOFs of heavy metal Cu (Ⅱ) adsorption.
