摘要
以樱桃月桂(Laurocerasus officinalisRoem.)种子(CLSAC)为原料，采用ZnCl2化学活化法制备了一种新型活性炭作为吸附剂去除水中的Cr(VI)离子。采用多种技术对CLSAC进行了表征，并在间歇式模型吸附技术下进行了吸附实验。考察了不同实验参数对溶液pH、接触时间、初始Cr(VI)浓度、CLSAC浓度和温度的影响。当CLSAC浓度为5.0 g L-1时，CLSAC的单层吸附量为41.67 mg g-1，可以作为一种有效的水、废水中Cr(VI)的吸附剂。
Application of cherry laurel seeds activated carbon as a new adsorbent for Cr(VI) removal
A novel activated carbon produced from cherry laurel (Laurocerasus officinalisRoem.) seeds (CLSAC) by chemical activation with ZnCl2 was used as an adsorbent to remove Cr(VI) ions from aqueous solutions. CLSAC was characterized by several techniques and the adsorption experiments were performed in a batch model adsorption technique. The effects of various experimental parameters were investigated as a function of solution pH, contact time, initial Cr(VI) concentration, CLSAC concentration, and temperature. The monolayer adsorption capacity of CLSAC was found to be 41.67 mg g-1 for 5.0 g L-1 of CLSAC concentration and, it was concluded that CLSAC can be used as an effective adsorbent for removal of Cr(VI) from waters and wastewaters.
