摘要
研究了溶液中硬脂酸改性磁铁矿的改性条件,确定了改性时间、温度、改性剂用量等。对改性磁铁矿进行了活化指数、吸油量、透水时间等的测定,并通过红外图谱及扫描电镜图谱的分析,探讨了改性及吸附机理。
The characteristics of oil adsorption by stearic acid - modified magnetite in aqueous solution, and the effect of factors （ time, modifier dosage, temperature ） on modification. The modified magnetite were measured activation index, oil absorption, permeability and etc. Meanwhile, under analysis of infared spectrum and scanning electron microscope, the mechanism of modification and adsorption was discussed.
