在黄河水中空气飞尘对磷酸盐吸附行为的研究

The Study of Adsorption Rule of Air-Dust on the Phosphata in the Yellow River Water

本文采用呼和浩特市空气飞尘与黄河水反应的吸附等温线方法来研究其吸附作用的规律,并对EPC0值定量数值进行了分析。研究表明,随着磷酸盐浓度的升高,空气飞尘对磷酸盐的吸附量呈线形的增加,飞尘的零平衡时磷酸盐浓度(EPC0值)在0.02~0.35m g/L之间;随固体浓度的升高,吸附等温线有所不同。飞尘的等温线是与坐标轴交叉的河流新型等温线,线性吸附系数(K)值在0.05~0.13L/g之间。

The adsorption rule of air-dust to the phosphate was studied with the method of adsorption uniform temperature line of air-flying to the phosphate,and the EPC0 value quota value was analysised.The research indicated that the adsorption capacity of the air of dust on phosphate was linear increased with the concentration of phosphate increased,when the dust was in the zero balance the concentration of phosphate(EPC0 value) was between 0.02 and 0.35mg/L;the adsorption uniform temperature line was different as ...
