摘要
利用合成的针铁矿对水中硫酸根离子进行吸附试验。试验表明 ,吸附量主要受pH值和硫酸根离子浓度影响。通过配位体交换理论 ,很好地解释了吸附量随pH下降而增加 ,随硫酸根离子浓度的下降而减少。
Sulfate is removed from aqueous solutions adsorbed on synthetic goethite during laboratory. Experimental results show that the amount of adsorption is mainly affected by pH value and sulfate concentrations. Based on ligand exchange theory,it can be explained that the amount of adsorption increases with decrease of pH value and reduces with decrease of sulfate concentrations.
