应用液闪分析手段,简要地研究了pH值对63Ni在泥煤中吸附的影响。结果表明,63Ni迅速地被泥煤吸附而达到吸附平衡,水相pH值的增加有利于泥煤的吸附。63Ni在泥煤上吸附动力学行为可以很好地用假二级反应进行描述。
The effect of pH value on the adsorption of 63Ni in peat was studied briefly by means of liquid-flash analysis. The results showed that 63Ni was quickly adsorbed by peat to reach adsorption equilibrium, and the increase of pH in aqueous phase was favorable to the adsorption of peat. The adsorption kinetics of 63Ni on peat is well described by pseudo-secondary reactions.
