摘要
研究了羟基磷灰石对水溶液中锌离子的吸附动力学.研究结果表明羟基磷灰石对水溶液中锌离子的吸附符合Langmiur等温吸附:ρR/q=0.15297ρR+0.12247;该吸附反应符合二级反应动力学方程:1/ρR=0.01084t+0.49689;反应速率k1和温度T之间的关系符合阿仑尼乌斯(Arrhenius)公式:lnk1=-0.89525×1/T+0.15541,吸附的活化能为Ea=7.444J/mol.
The adsorption kinetics of aqueous zinc on hydroxyapatite is researched in this paper. The results show, that the adsorption isotherm fitted well with Langmiur equation. ρR/q=0.15297 ρR＋0.12247 the reaction of adsorption is the second reaction kinetics equation. 1/ρR=0.01084T＋0.49689 the relationship between reaction rate constant kl and temperature T accords with Arrhenius equation. lnk1=-0.89525×1/T＋0.15541 ,the activation energy Eα is 7. 444 J/mol.
