摘要 以NaOH皂化改性的橘子皮为吸附剂,并以橘皮粉投加量(Q)、pH值、搅拌速度(n)、温度(T)、吸附时间(t)为考察因素,对自制模拟实验室含铜废液进行了吸附实验。通过原子吸收分光光度法(Atomic Absorption Spectrometry,AAS)测定了吸附前后水中Cu^(2+)的浓度,并探讨了在不同试验条件下,橘皮粉对铜离子的吸附率。最适宜吸附条件为:Q 25.00 g/L、pH值4.00、r 120 r/min、T室温(15~35℃)、t 60 min。 Na OH-modified Orange peel was used for the absorption of the copper(II) ion from the Lab-wastewater.Dosage of orange peel(Q),pH value,adsorption temperature(T),mixing rate(n) and adsorption time(t) were studied as the effection factors.Atomic Absorption Spectrometry(AAS) method was used for the measurements of the concentration of Cu^2+ and adsorption efficiency was studied under the various factors above.Optimum conditions are Q 25.00 g/L,pH4.00,n 120 r/min,T(15 ~ 35℃),t 60 min.
