【摘要】 用三氯化铁或硫酸铝作沉淀剂 ,沉淀腐植酸钠 ,实验发现当腐植酸钠与三氯化铁或硫酸铝的质量比分别为 1∶ 0 .6 4和 1∶ 0 .6 0时 ,沉淀效果最好。并且用腐植酸钠配合三氯化铁或硫酸铝作絮凝剂 ,处理高岭土悬浊液 ,实验表明 ,其除浊效果比单独用三氯化铁或硫酸铝处理该悬浊液时更好。更多还原

【Abstract】 Iron trichloride or aluminium sulfate was used as a precipitating agent to precipitate sodium humic acid.It was found in experiment thatwhen the mass ratio of sodium humic acid with iron trichloride or aluminium sulfate was1 to0 .6 4 or1 to0 .6 0 ,the precipital effect was the best.And sodium humic acid was used as flocculant agent mixed with iron trichloride or aluminium sulfate to treat aqueous suspension of kaolin.Itshowed that the effect of turbidicy removal is superior to that of using only iron trichloride or aluminium sulfate to treat the aqueous suspension.更多还原
