研究了橙子皮对酸性紫17的吸附效果，考察了搅拌时间、吸附剂用量、染料初始浓度和pH值对吸附效果的影响。初始pH为6.3时，吸附容量Q 0为19.88 mg/g。当染料浓度分别为10、20、30和40 mg/L时，平衡时间为80 min。当染料浓度为10 mg/L，吸附剂投加量为600 mg/50 ml时，在pH = 2.0时，染料的最大去除率为87%。吸附随pH值的增加而增加。在pH 10.0的水介质中实现了60%的最大解吸。
The effectiveness of orange peel in adsorbing Acid violet 17 from aqueous solutions has been studied as a function of agitation time, adsorbent dosage, initial dye concentration and pH. The adsorption follows both Langmuir and Freundlich isotherms. The adsorption capacity Q0was 19.88 mg/g at initial pH 6.3. The equilibrium time was found to be 80 min for 10, 20, 30 and 40 mg/L, dye concentration respectively. A maximum removal of 87% was obtained at pH 2.0 for an adsorbent dose of 600 mg/50 ml of 10 mg/L dye concentration. Adsorption increases with increase in pH. Maximum desorption of 60% was achieved in water medium at pH 10.0.
