摘要: 研究了多组分背景下2种煤质颗粒状活性炭D1220、R08S对人尿中4种药活性化合物(PhACs)(1 mg/L)——苯扎贝特(BEZ)、卡马西平(CAR)、布洛芬(IBU)和美托洛尔(MET)——的吸附去除。结果表明,D1220(R08S)对4种PhAC的吸附均符合Freundlich等温式,均为优惠吸附;D1220(R08S)对各PhAC的吸附作用强弱顺序为BEZ>CAR>MET>IBU(BEZ>CAR>IBU>MET);PhACs平衡浓度小于3.01(0.91)μg/L时,D1220(R08S)对4种PhACs中的BEZ的吸附性能最好,平衡浓度大于3.01(1.93)μg/L时,D1220(R08S)则对MET的吸附性能最好;活性炭投加量为2 g/L时,D1220(R08S)对4种PhAC的去除率均在88%以上;总体吸附性能D1220优于R08S。

Abstract: Considering the fact that human urine is probably the main source of PhACs present in aquatic environment which could pose potential risks to aquatic organisms or even humans, the removal of Bezafibrate (BEZ), Carbamazepine (CAR), Ibuprofen (IBU) and Metoprolol (MET) from human urine by two coal-based granular activated carbons (GACs), D1220 and R08S, was studied. The results showed that all the adsorption processes obeyed the Freundlich isotherm and were favorable. The strength of adsorption of PhACs onto D1220 (R08S) followed the sequence: BEZ>CAR>MET>IBU (BEZ>CAR>IBU>MET). While the equilibrium concentration of each PhAC was less than 3.01 (0.91) μg/L, D1220 (R08S) showed the best adsorption performance on BEZ, and while the equilibrium concentration was greater than 3.01 (1.93) μg/L, D1220 (R08S) showed the best adsorption performance on MET. As concentration of D1220 (R08S) was 2 g/L, removal rates of all PhACs at least 88% were achieved. Overall, in comparison with R08S, D1220 showed a better adsorption performance.
