摘要
In this paper, the role of pH value on the adsorption of Hg2+ on the laterite from Guizhou Province was studied. The lower pH is unfavorable to the adsorption of Hg2+ whereas the higher pH is favorable to the adsorption of Hg2+. When pH reached a certain value, the amount of Hg2+ adsorption reached the maximum. Then the amount of Hg2+ adsorption was reduced with increasing pH value.
In this paper, the role of pH value on the adsorption of Hg^2＋ on the laterite from Guizhou Province was studied. The lower pH is unfavorable to the adsorption of Hg^2＋ whereas the higher pH is favorable to the adsorption of Hg^2＋. When pH reached a certain value, the amount of Hg^2＋ adsorption reached the maximum. Then the amount of Hg^2＋ adsorption was reduced with increasing pH value.
