摘　　要：在此以ZnFe2O4为磁性内核,利用液体石蜡作有机分散介质、甲醛、戊二醛作交联剂,通过反相悬液交联法制备出了单分散、窄分布的磁性ZnFe2O4壳聚糖核壳微球,并利用其吸附作用来处理苯酚废水溶液,同时使用紫外分光光度计来测其吸光度的变化。分吸附剂的投加量,pH值的变化,吸附时间不同的3种情况来讨论。Taking ZnFe2O4 as the magnetic core, the liquid paraffin as organic dispersion medium, and the formaldehyde, the glutaric dialdehyde as the crosslinking agent, through the crosslinking method of antiphase suspensions, the mono disperse and the narrow distribution magnetic ZnFe2O4 chitosan microsphere is prepared, which adsorptive function is applied to process the phenol wastewater, simultaneously the change of absorbance is measured used the ultravioletspectrophotometer. Three different conditions, including dosage of absorbent, pH value and adsorption time are discussed in this article respectively.
