阴离子对Al_2O_3吸附MoO_4^(2-)的影响

Effect of Anion on the Alumina Adsorption of MoO_4^(2-)

本文报导了分别在磷酸盐、硅酸盐、硫酸盐、硝酸盐溶液中MoO_4^(2-)在中性Al_2O_3上的吸附情况,结果发现,MoO_4^(2-)的吸附量随着溶液的阴离子浓度和pH值而变化,其对吸附的影响情况与Hsu在酸性溶液中的结果是一致的.

Adsorption of MoO_4^(2-) on the neutral alumina has been carried out with the addition of phasphate, silicate, sulphatn, nitrate.It is found that the amount of the adsorbed MoO42- changed with pH and concentration of anionic solution and is proved that the adsorbed influence is agreement with Hsu's conclusion in acid solution.
