| 摘 要： | 将颗粒活性炭碾磨处理后用于吸附乳酸钠,并采用单因子实验考察溶液pH值、温度对活性炭吸附量的影响。对吸附等温线的分析表明,碾磨时间不同的活性炭对乳酸钠的吸附行为均可用Freundlich方程描述,对比吸附常数和固相-水分配系数发现,碾磨30 min后活性炭的吸附能力最强;碾磨活性炭吸附乳酸钠的最佳pH为7.0,且吸附量受温度的影响不大。

| Abstract: | Four kinds of milled granule active carbons were used to adsorb sodium lactate through batch experiments.The adsorption isothermal curve,pH value of solution,and temperature were studied using one-factor experiment.The adsorption isotherms were analyzed.The results show that with the regression analysis of data,the adsorption behaviors of sodium lactate can be well described by Freundlich equation.The adsorption constant and distribution coefficient show that the adsorption capacity of granular active carbon(GAC) milled for 30 min is the strongest,the best pH value is 7.0,and the effect of temperature on adsorption capacity is little. |
