摘要:
通过柠檬酸对酒糟改性后制备出改性酒糟,系统研究了改性酒糟对水溶液中重金属Cd的吸附性能.研究发现,质量浓度0.5%的柠檬酸改性酒糟对Cd2+的吸附量由改性前的4.09 mg/g提高到9.13 mg/g;酒糟改性后比表面积增大,微孔容积增加,且电负性增强.红外光谱分析表明,经过柠檬酸改性后酒糟有效官能团数目增多.改性酒糟对Cd2+的吸附量随pH值的升高先增加后略有降低,在2 h时达到吸附平衡,吸附饱和后随震荡时间的延长,Cd2+析出量很小.当pH值为6、初始Cd浓度为100 mg/L、改性酒糟投加量为10 g/L、吸附120 min时,改性酒糟对Cd2+的去除率达到 91.50%,吸附量为9.15 mg/g.吸附等温线研究表明,Langmuir模型能更好地描述改性酒糟对Cd2+的吸附过程.
Abstract:
The modified distiller grain(MDG)was prepared by using citric acid and the adsorption property of MDG on the heavy metal cadmium ions in aqueous solution was investigated. The results show that the adsorption capacity of the distiller grain modified by the citric acid with the concentration of 0.5% on the cadmium ions increases from 4.09 mg/g before modification to 9.13 mg/g. The specific surface area, micropore volume and the electro-negativity of MDG increase after modification. Infrared spectrum analyses indicate that the number of effective groups of the distiller grain modified by citric acid increase. The adsorption quantity of cadmium ions increases at first and then slightly decreases with the increasing of pH value, reaching adsorption equilibrium after 2 h. After adsorption saturation, the dissolved quantity of cadmium ions is very small with the prolonging of time. When the pH value is 6, the initial concentration of cadmium ions is100 mg/L, the MDG dosage is 10 g/L, and the adsorption time is 120 min, the removal rate and adsorption quantity of cadmium ions by MDG can reach 91.50% and 9.15 mg/g, respectively. Results of adsorption isotherm show that the Langmuir model can well describe the adsorption process of MDG on the cadmium ions well.
