研究了水体中常见离子对蛋壳粉吸附溶液中磷的影响。实验结果表明，SO2－4、Cl－和NO－3的存在，对天然蛋壳粉吸附磷过程产生协同作用，但协同作用不明显；HCO－3表现出吸附抑制作用；Ca2＋和Mg2＋表现出较为显著的吸附协同作用，其中Ca2＋最为显著；NH＋4离子存在时，几乎不产生影响。富集系数和吸附平衡下降率均可有效表述常见离子对蛋壳粉吸附磷过程的影响程度。
This work investigated the effects of common irons on phosphorous adsorption by eggshell. The experimental results suggest that the uptake of phosphorous on eggshell increased slightly in the presence of SO2-4 , Cl-and NO-3 , yet declined sharply with the existence of HCO-3 . Meanwhile, Ca2+and Mg2+ increased the loading of phosphorous on eggshell dramatically, especially in the case of Ca2+. On the other hand, adding NH+4 into the solution did not show any effect on phosphorous adsorption. Enrichment factor and ratio of adsorption equilibrium both can illustrate the effect of common ions on phosphorous adsorption by eggshell.
