摘要
以巯基泥炭为分离富集剂 ,对重金属离子的单组分或多组分溶液进行吸附研究 ,探讨了吸附剂的吸附性能、影响吸附因素和吸附机理。实验表明 :巯基泥炭是一种价廉、高效的重金属固体吸附剂 ,在pH =5 ,低温下较未处理泥炭吸附量提高 5倍左右 ;对重金属离子的吸附均表现出Langmuir特征。
With sulfhydryl peat as adsorbent,the adsorption of heavy metal ions in aqueous solution was studied.The specific properties of adsorbent,the influencing factors and mechanism of adsorption were investigated.The results indicated that the adsorption isotherms conformed mainly to Langmuir equation and the adsorbent had high capability of concentration.
