| description | The invention belongs to the field of solid waste resource utilization and environmental protection, and particularly relates to a method for preparing a magnetic Pb (II) adsorbent from coal slime. The method comprises the following steps: mixing coal slime and red mud according to a certain ratio, and carrying out high-temperature carbonization in a nitrogen atmosphere to obtain the magnetic Pb (II) adsorbent. According to the method, the coal slime and the red mud are used as raw materials, efficient resource utilization of the coal slime and the red mud can be achieved, and a new way is provided for low-cost efficient preparation of the magnetic Pb (II) adsorbent.
本发明属于固废资源化利用和环境保护领域，尤其涉及一种利用煤泥制备磁性Pb(Ⅱ)吸附剂的方法。该方法包括：将煤泥和赤泥按一定比例混合后，于氮气气氛下进行高温炭化，得到磁性Pb(Ⅱ)吸附剂。本发明方法利用煤泥和赤泥作为原料，可实现煤泥和赤泥的高效资源化利用，为低成本高效制备磁性Pb(Ⅱ)吸附剂提供了新途径。 |
