摘要: 以松树锯末为吸附剂,研究其对水中Pb(II)和Ni(II)的吸附性能,研究了锯末用量、搅拌速度、溶液初始pH值等对吸附效果的影响及其吸附动力学和热力学性能。研究结果表明,锯末对Pb(II)和Ni(II)具有良好的吸附能力。锯末对Pb(II)和Ni(II)吸附过程均符合拟二级吸附动力学模型(R2≥0.997 7),锯末吸附Pb(II)和Ni(II)的活化能分别为9.808 7 kJ/mol和2.859 4 kJ/mol;锯末对Pb(II)和Ni(II)等温吸附符合Langmuir模型(R2≥0.999 2)。热力学研究表明,锯末对Pb(II)和Ni(II)的吸附是自发的放热过程。

关键词: Ni(II), 动力学, 热力学, 吸附, Pb(II), 锯末

Abstract: Sawdust was used to remove Pb(II) and Ni(II) from water as an absorbent. Effects of sawdust dosage, stirring speed and pH on the adsorption capacity, adsorption kinetics and thermodynamics were discussed. The results showed that sawdust had a good adsorption capacity for Pb(II) and Ni(II). The adsorption process corresponded with pseudo-second-order kinetic model (R2≥0.997 7), the activation energy were 9.808 7 kJ/mol for Pb(II) and 2.859 4 kJ/mol for Ni(II), respectively. The adsorption isotherms of Pb(II) and Ni(II) were consistent well with the Langmuir isotherm (R2≥0.999 2). Thermodynamics analysis showed that the adsorption process was spontaneous and exothermic.

Key words: sawdust, Pb(II), Ni(II), adsorption, thermodynamics, kinetics
