摘　　要：为了开发利用钢渣的吸附性能,研究了钢渣细度、用量、溶液温度、pH值对钢渣吸附去除淀粉的影响以及钢渣吸附淀粉的动力学曲线和等温吸附方程,试验结果表明,钢渣对可溶性淀粉的吸附速度快,吸附容量大,吸附过程符合Langmuir等温吸附方程,动力学过程可用Langergen准一级反应动力学方程描述。The effects of steel slag granularity and dosage, solution temperature and pH on the adsorption ratio of soluble starch with steel slag were discussed, and its kinetics was studied, and the adsorption isotherm was determined. The result indicates that the adsorption speed of soluble starch with steel slag is rapid and the adsorption capability is high, the adsorption isotherm of soluble starch with steel slag follows the Langmuir model, its kinetics equation can be described by pseudo-first order reaction.
