摘要
利用硫酸镁和造纸草浆黑液制备含镁氧化合物的吸附剂,通过化学分析、表面性质分析、X射线衍射和红外光谱等对吸附剂进行了表征。考察了吸附剂焙烧温度、投加量、吸附时间以及pH值等因素对活性黄ST-4RFN吸附性能的影响,吸附过程可用Freundlich模型来描述。
An absorbent containing magnesia oxides has been prepared from straw pulp black liquid and magnesium sulfate, and the characters of the absorbent have been tested by chemical analysis, surface analysis, X- ray diffraction （XRD） and infrared ray （IR）. The factors influencing its adsorption of Reactive yellow ST- 4RFN, such as calcination temperature, dosage, adsorption time, and adsorption temperature, have been examined, and the adsorption process was found to be in accord with the Freundlich model.
