摘要
研究了茶叶渣对Ni(Ⅱ)的吸附动力学特性。在茶叶渣量1.2 g、pH5.5、温度25℃、吸附时间1 h条件下,研究了不同Ni(Ⅱ)初始浓度(120 mg/L、200 mg/L、320 mg/L、600 mg/L、800 mg/L、1 000 mg/L)的等温吸附曲线。得出了Langmuir、Freun-dlich及Temkin方程的有关参数。研究结果表明,Temkin等温吸附模型符合得更好。
The adsorption kinetics character of Ni（Ⅱ） with tea dust has been studied. The thermal adsorption model of Ni（Ⅱ） in the initial concentration of 120 rag/L,200 rag/L,320 rag/L,600 mg/L,800 rag/L, 1 000 mg/L has been investigated in the condition of waste tea dosage of 1.2 g, pH value of 5.5, temperature of 25 ~C, adsorp- tion time 1 h. The relative parameters of Langmuir, Freundlich and Temkin thermal adsorption equation were ob- tained. The result shows that the adsorption behavior of Ni（Ⅱ） with waste tea dust accords with Temkin model bet- ter.
