摘　　要：为高效解决选矿废水残余浮选药剂浓度高的问题,将活性炭和钙基膨润土分别作为吸附剂,系统探究了吸附剂用量、吸附时间、反应温度、溶液初始pH值等因素对废水中丁基黄药吸附性能的影响。试验结果表明:活性炭对丁基黄药的吸附量和去除率最大值分别为6.55mg/g和98.32%,而钙基膨润土对丁基黄药的吸附量和去除率最大值分别为2.73 mg/g和40.95%。通过X射线衍射(XRD)和傅里叶红外光谱(FTIR)对吸附材料吸附前后的结构变化进行对比表明,活性炭和钙基膨润土对丁基黄药的去除机制主要为物理吸附。In order to effectively solve the problem of high concentration of residual flotation reagents in mineral processing wastewater,activated carbon and calcium bentonite were used as adsorbents respec⁃tively.The effects of adsorbent dosage,adsorption time,reaction temperature and initial pH value of solu⁃tion on the adsorption performance of butyl xanthate in wastewater were systematically investigated.The re⁃sults showed that the maximum adsorption capacity and removal rate of butyl xanthate by activated carbon were 6.55 mg/g and 98.32%respectively,while the maximum adsorption capacity and removal rate of butyl xanthate by calcium bentonite were 2.73 mg/g and 40.95%respectively.The structural changes of the adsorp⁃tion materials before and after adsorption were compared by X-ray diffraction(XRD)and Fourier transform infrared spectroscopy(FTIR).The results showed that the removal mechanism of butyl xanthate by activated carbon and calcium bentonite was mainly physical adsorption.
