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6.55 mg/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.
Abstract
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.
