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.
The effects of common ions in water on phosphorus in the adsorption solution of eggshell powder were studied.The results showed that the presence of SO2-4, Cl- and NO-3 had a synergistic effect on the adsorption of phosphorus by natural eggshell powder, but the synergistic effect was not found Obviously; HCO-3 showed adsorption inhibition; Ca2 + and Mg2 + showed more significant synergistic effect of adsorption, of which Ca2 + was the most significant; NH4 + ion had almost no effect, enrichment coefficient and adsorption equilibrium descent rate Effective expression of common ions on the eggshell powder adsorption process of phosphorus extent.
