摘要

研究了活性炭和酰胺基活性炭在接触时间、吸附剂质量、pH和处理金属离子初始浓度等条件下对水溶液中Ni(II)、Zn(II)和Co(II)的吸附能力。通过批量实验考察了其吸附能力。结果表明，增加吸附剂的质量、接触时间、溶液pH和处理后金属离子的初始浓度均能提高去除率。以山毛榉木屑为原料制备活性炭，在pH=5、金属离子初始浓度为100 mg/L、振荡2 h时，提高金属离子去除率的最佳顺序为:Zn(II) 本文章由计算机程序翻译，如有差异，请以英文原文为准。

Removal of Ni(II), Zn(II) and Co(II) from Aqueous Solutions by Using Different Types of Activated Carbon

The adsorption capacity of activated carbon and activated carbon with amide group towards Ni(II), Zn(II) and Co(II) from aqueous solutions was studied in varying treatment conditions such as contact time, weight of sorbent, pH and initial concentration of treated metal ions. The adsorption capacity was investigated by batch experiments. The results showed that the removal percentages were enhanced by increasing the weight of the added sorbent, contact time, pH of the solution and the initial concentration of treated metal ions. The optimum order of increasing removal percentages of metal ions by using activated carbon (AC) prepared from sawdust of beech wood at pH=5, with an initial concentration of metal ions of 100 mg/L, and after two hours of shaking, was: Zn(II)

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
