用柚子皮作为吸附剂对染料废水进行脱色吸附研究,分析了吸附剂用量、初始pH、反应时间、反应温度、染液质量浓度等因素对柚子皮脱色吸附能力的影响.结果表明：废水初始质量浓度为20 mg/L、柚子皮用量为20 g/L、初始pH=11、反应温度为35℃,反应时间为15 min时,脱色率达到79.62%,吸附容量为3.1726 mg/g.%Using pomelo peel as adsorbent for dye wastewater, the adsorption and decolorization were studied. The effects of adsorbent dosage, the initial pH, reaction time, reaction temperature and dye concentra⁃tion on the decolorization and adsorption ability of pomelo peel were analyzed. The experimental results showed that initial concentration of wastewater was 20 mg/L, the amount of pomelo peel was 20 g/L, the ini⁃tial pH was 11, the reaction temperature was 35 ℃, and the reaction time was 15 min. Under the above condi⁃tion the decolorization rate reached 79.62%and the adsorption capacity was 3.172 6 mg/g.
