摘要
本文以龙口褐煤作吸剂,对重金属离子Ni^(2+),Mn^(2+),Hg^(2+)的单组分水溶液进行吸附研究,探讨了吸附剂的吸附性能、影响吸附的因素和吸附机理.结果表明:褐煤对Ni^(2+),Mn^(2+),Hg^(2+)的吸附均表现出Langmuir特征,pH值是影响吸附的一个重要因素.
With Longkou lignite as an adsorbent, the adsorption of Ni2 + , Mn2 + and Hg2 + ions in aqueous solution, the specific properties of adsorbent, the effect elements and the mechanism of adsorption were studied in present paper. The results indicated that the adsorption isotherms were mainly conformed to Langmuir equation and pH value was an important factor in adsorption process.
