Study on adsorption characteristics of sepia melanin adsorbing Pb2+

Ocean Institute of Ningbo University

摘要

摘要: 以乌贼墨黑色素作为吸附剂对Pb2+进行吸附,分别考察初始离子浓度、溶液pH、吸附温度、吸附作用时间、乌贼墨黑色素添加量对吸附的影响。结果表明,pH4⁵时,吸附率最高,温度对吸附基本不产生影响,乌贼墨黑色素对Pb2+的吸附率随初始离子浓度增大而下降,随吸附时间延长和吸附剂添加量增加而增加直至吸附饱和。乌贼墨黑色素对Pb2+的吸附过程符合Langmuir等温线方程和准二级动力学方程,吸附过程以单层吸附为主。

Abstract: Sepia melanin was used as adsorbent for absorbing Pb2+ from water. The influences of Pb2+ initial concenration, pH value, adsorbing temperature, adsorbing time and sepia melanin contents on the adsorption effect of sepia melanin onto Pb2+ were discussed. The results indicated that when pH value was 4⁵, the Pb2+ absorbing amount reached the highest. The temperature almost didn't affect the adsorption. The absorbing rate decreased against the increase of Pb2+ initial concenration, while it increased with the increasing of adsorbing time and sepia melanin contents until it reached saturation adsorption. Adsorption process of Pb2+ by sepia melanin was in accordance with the Langmuir models and pseudo-second-order reaction equation and obeyed to the rule of single element layer.
