Abstract
- A series of novel resin-based MOF composites Co-MOF@D113-N (N = 1, 6) were prepared using 2-methylimidazole, cobalt acetate and D113 resin, through the layer-by-layer self-assembly method. The Co-MOF presented an amorphous form with the inducement of resin groups and the loading capacity increased with the number of self-assembled layers. The strong anchoring effect between Co and N effectively improved the thermal stability of the composites. The adsorption experiments showed that the adsorption capacity of the Co-MOF@D113-6 resin for Cu(II) increased with temperature in the range of 283ā303 K. The adsorption capacity of Co-MOF@D113-6 for Cu(II) increased under the synergistic effect of MOFs and D113. The maximum adsorption capacity of Co-MOF@D113-6 was 273.88 mg gā1. The fitting results showed that the adsorption of Cu(II) by the Co-MOF@D113-6 conformed to the pseudo-second-order kinetic model dominated by chemisorption, and also conformed to the preferential Freundlich adsorption isotherm model. A low cost resin carrier combined with a high efficiency MOF composite adsorption material provided high efficiency and low consumption for promising development. [ABSTRACT FROM AUTHOR]
