摘要:
为解决电镀废水中重金属铅污染问题，通过碳化对混凝土微粉(WCP)进行活化制备了碳化混凝土微粉(CWCP)吸附材料，通过XRD、傅里叶变换红外光谱(FT-IR)、SEM以及热重(TG)和微分热重(DTG)表征了CWCP的物相晶型、化学组成、微观形貌和热失重过程。以Pb(NO3)2溶液作为模拟重金属Pb(Ⅱ)废水，评价了碳化时间、投加量和初始pH对CWCP吸附性能的影响，探讨了吸附机制。结果表明：碳化可有效提高CWCP吸附Pb(Ⅱ)能力，碳化48 h的CWCP对Pb(Ⅱ)吸附量相比WCP提高了25.23%。在Pb(Ⅱ)初始浓度为500 mg/L，CWCP投加量为1.0 g/L，初始pH为5.0和吸附温度为25 ℃条件下经过1 440 min的吸附，CWCP对Pb(Ⅱ)吸附量和去除率分别为499.82 mg/g和99.96%，表现出优异的吸附能力。准二级动力学模型和Freundlich等温吸附模型可以较好地反映吸附过程，吸附过程以化学吸附为主，溶液中Pb(Ⅱ)和CWCP的主要组成Ca(OH)2和CaCO3发生沉淀反应生成白铅矿。
Abstract:
In order to solve the problem of heavy metal lead pollution in electroplating wastewater. The carbonized concrete powder(CWCP) adsorbent material was prepared by activating concrete powder (WCP) through carbonization. The phase crystal form, chemical group, microstructure and thermal weight loss process of CWCP were characterized by XRD, Fourier transform infrared spectroscopy (FT-IR), SEM, thermogravimetric(TG) and differential thermogravimetric (DTG). The Pb (NO3)2 solution was used as a simulated heavy metal Pb(II) wastewater. The effects of carbonization time, dosage and initial pH on the adsorption performance of CWCP were evaluated, and the adsorption mechanism was analyzed. The results show that carbonization can effectively improve the adsorption capacity of CWCP for Pb(II). The adsorption capacity of CWCP for Pb(II) after carbonization for 48 h is 25.23% higher than that of WCP. Under the conditions of initial Pb(II) concentration of 500 mg/L, CWCP dosage of 1.0 g/L, initial pH of 5.0 and adsorption temperature of 25 ℃, the adsorption capacity and removal rate of CWCP for Pb (II) were 499.82 mg/g and 99.96%, respectively, after 1 440 min of adsorption, showing excellent adsorption capacity. The pseudo-second-order kinetic model and Freundlich isothermal adsorption model can betterly reflect the adsorption process. The adsorption process is mainly chemical adsorption. The main components of Pb(II) and CWCP in the solution, Ca(OH)2 and CaCO 3, precipitated to form cerussite
