研究了用浸渍了腐植酸的活性炭(AC)从水生环境中去除汞(Ⅱ)。AC的汞吸附容量受比表面积和表面的官能团控制,在这项研究中,汞吸附过程对应于一个Lagergren的准二级模型,表明在AC上的吸附是化学吸附而不是物理吸附。此
The removal of mercury (II) from aquatic environments by activated carbon impregnated with humic acid (AC) was studied. The mercury adsorption capacity of AC is controlled by the specific surface area and the surface functional groups. In this study, the mercury adsorption process corresponds to a Lagergren quasi-second-order model, indicating that the adsorption on AC is not chemical adsorption but physical adsorption. this
