摘要
利用柠檬酸对甘蔗渣进行改性,研究改性后甘蔗渣上重金属吸附及再生性能,并采用TG-DSC,电镜扫描与红外光谱对改性前后的甘蔗渣进行表征。结果表明,经柠檬酸改性后大量羧基官能团引入甘蔗渣内部,增加了甘蔗渣表面活性位点的数量,赋予吸附剂更为理想的吸附能力。
Regeneration properties of citric acid modified bagasse and its adsorption activity for heavy metals were studied.The bagasse was characterized by TG-DSC,SEM and IR before and after modification.The results showed that a large number of carboxyl functional groups were introduced into bagasse after modification,which increased the number of active sites on the surface of bagasse and endowed the adsorbent with more ideal adsorption capacity.
