摘要
研究了柚子皮对甲基橙(MO)的吸附行为,考察了吸附时间、溶液p H值、柚皮粉用量和MO初始浓度等因素对吸附效果的影响。结果表明,在MO溶液p H值为5.0,初始浓度为10 mg/L的条件下,25 m L溶液中添加0.05 g的柚子皮粉,以120 r/min振荡吸附60 min后,MO吸附率可达77.65%,酸性环境有利于MO吸附。一定范围内,柚子皮用量的增加以及MO初始浓度的升高都会导致吸附率升高,柚子皮粉对MO的吸附过程以物理吸附为主,符合Langmuir吸附等温方程。
The adsorption performance of pomelo condition of pomelo peel to the dye waste water were pomelo Peel to 25 mL 10 mg/L MO reached about adsorption pattern of pomelo peel to MO was physical describe the adsorption process of pomelo peel to MO. peel to the MO was studied, the adsorption regulation and optional analyzed. The results showed that the MO removal rate of 0. 05 g 77.65% under the condition of pH 5.0 and 60 rain. The main adsorption, adsorption rate equation of Langmuir could be used to
