摘　　要：为了扩展高硫石油焦的应用领域,研究高硫石油焦基炭分子筛对铬离子的吸附性能,以高硫石油焦为原料,按照不同的粒度和碱炭比制备了一系列炭分子筛,并对模拟含铬离子废水进行了吸附性研究。结果表明,高硫石油焦基炭分子筛对Cr^(6+)吸附的最佳参数:Cr^(6+)初始质量浓度0.100 0 mg/mL,吸附时间20 min,吸附温度40℃,Cr^(6+)平衡质量浓度0.081 9 mg/mL,最大吸附量12.696 2 mg/g,最大吸附率18.1%。In order to expand the application of high sulfur petroleum coke,and to study the adsorption performance of high sulfur petroleum-coke based carbon molecular sieves for chromium ion,a series of carbon molecular sieves were prepared with high sulfur petroleum coke as raw material according to different particle sizes and alkali carbon ratios,and their adsorption properties for simulated chromium-containing wastewater were studied.The results show that the optimal Cr6+adsorption parameters of the sieves are as follows:initial Cr6+concentration of 0.1000 mg/mL,adsorption time of 20 min,adsorption temperature of 40℃,equilibrium Cr6+concentration of 0.0819 mg/ml,the maximum adsorption capacity of 12.6962 mg/g,and the maximum adsorption rate of 18.1%.
