| 摘 要： | 研究了大洋锰结核氨浸渣脱硫产物去除废水中镉离子的多种影响因素,如接触时间、脱硫产物粒径、溶液pH值、初始镉离子浓度和吸附剂量。并利用X射线粉末衍射(XRD)、场扫描电镜(SEM)、X射线光电子能谱(XPS)对材料和产物进行了表征。结果表明减小脱硫产物粒径、增大吸附剂量等有利于提高去除效果;大洋锰结核氨浸渣脱硫产物去除水中镉离子是基于离子交换反应的原理:MnS+Cd2+→CdS+Mn2+。

| Abstract: | In this study,the removal of Cd2+ from aqueous solutions by desulfurization products of manganese nodule leached residue was carried out in consideration of the influence of various parameters,such as contact time,solution pH and initial metal concentration,and adsorbent quantity.X-ray diffraction(XRD),scanning electron microscopy(SEM)and X-ray photoelectron spectroscopy(XPS)were used to characterize the materials and products.The adsorption of Cd2+ increased with the increase of the adsorbent in solution,a... |
