微波-浸渍联合改性活性炭对CS2吸附性能的研究
Adsorbility of CS2 on Modified Activated Carbon by Impregnation-Microwave
摘要
Abstract
Activated carbon (AC) was modified through microwave radiation and then impregnation with transition metal (Fe3+ , Cu2+) and ammonia with orthogonal experimental design. The modified activated carbon was used in adsorbing CS2. The effects of microwave power, radiation time and activated carbon dosage in the modification on adsorption of CS2 on the modified activated carbon were investigated. Under the optimal conditions of microwave power 400 W, radiation time 3 min and AC dosage 5 g, the adsorptive capacity of the activated carbon(AC1) modified only by microwave for CS2 in stable state and dynamic state increased to 0. 564 and 0. 542 g/g, respectively. When AC1 was improved by impregnation with 0. 005 mol/L Fe( NO3) 3 solution, 0.020 mol/L Cu( NO3) 2 solution or 30% (w) ammonia solution, its adsorptive capacity for CS2 was heightened, among which, the adsorptive capacity of AC1 obtained by impregnation with 30% (w) ammonia solution was the highest, 0. 587 g/g in the stable state and 0. 572 g/g in dynamic state. The modified activated carbon was characterized by means of BET, SEM and FTIR. The results showed that both the numbers of the surface basic groups and the micropores of the modified activated carbon increased.关键词
