HKUST-1@MoS2热解产物的制备及其对水中磺胺嘧啶的吸附性能
Preparation of HKUST-1@MoS2 pyrolysis products and its performance on sulfadiazine adsorption from aqueous solutions
摘要
Abstract
A type of new adsorbent(HK-M-300)was prepared by using a typical copper-based metal-organic skeleton material of HKUST-1 as the base material,MoS2 as the outer layer compounded material and a high-temperature pyrolysis method.SEM,XRD,BET,FTIR,XPS and other methods were used to characterize the physical and chemical properties of the adsorbents,the composite ratio of raw materials and pyrolysis temperature during the adsorbent preparation were optimized.The adsorption performance of sulfadiazine(SDZ)on HK-M-300 was systematically studied,and the effects of adsorbent dosage,pH,and coexisting ions(Cl-,NO3-,CO32-and PO43-)on the adsorption performance were also investigated.The results showed that the stability and adsorption performance of the prepared HK-M-300 increased significantly.When the adsorbent dosage was 0.2 g·L-1 and the mass concentration of SDZ solution was 5 mg·L-1,higher than 96％of the SDZ could be adsorbed by HK-M-300 within 180 min,which was 54％higher than that of HK-300 prepared by direct pyrolysis of HKUST-1,moreover,the leakage of Cu metal in the solution treated with HK-M-300 adsorbent was reduced to 13％of that treated with HK-300.The pseudo-second order kinetic model could better fit the adsorption process,and the adsorption isotherm could be well fitted by the Sips and Freundlich models.Hydrogen bonding and π—π interactions were the main mechanisms for the adsorption of SDZ by HK-M-300.关键词
