| description | According to the present invention, magnetic shell charcoal is prepared by using agricultural and forestry waste walnut shell as a main raw material, such that the problem that the existing active carbon adsorbent is difficult to recycle is solved; treated walnut shell charcoal powder is soaked with a ferric chloride and ferrous chloride mixing solution activator, and sodium hydroxide is adopted as a precipitant to prepare the novel adsorbent; and the conventional shell charcoal is magnetized in the present invention compared to the conventional shell charcoal, such that the adsorbent can quickly perform solid-liquid separation through the effect of the external magnetic field so as to eliminate centrifugation and other cumbersome steps.
本发明以农林废弃物核桃壳为主要原料制备磁性壳炭，解决现有活性炭吸附剂难以回收利用的问题。通过将已处理好的核桃壳炭粉经氯化铁和氯化亚铁混合溶液活化剂进行浸泡，以氢氧化钠为沉淀剂，制备成种新型的吸附剂。与普通壳炭相比，本发明对普通壳炭进行了磁化，致使该吸附剂通过外界磁场的作用能够迅速地进行固液分离，省去了离心等繁琐的步骤。 |
