摘要
采用多细胞藻类裙带菜对重金属镍离子进行吸附,研究溶液的pH值,初始Ni2+浓度,裙带菜的粒度、处理温度及不同生长时期等因素对Ni2+的吸附特性的影响。得到最佳pH值4-6及最大吸附量0.7591mmol/g,并用Langmuir和Freundlich方程对裙带菜的吸附等温线进行了拟合。
Undaria pinnatifida as a biosorbent was investigated at different pH, initial nickel concentration, particle sizes, treated temperature and different period of growth. Nickel adsorption was strongly depent on pH and has a wide range of proper pH of 4-6. A maximum of nickel uptake was 0.7591mmol/g derived ,which ishigher than that of other algae reported in literatures .In addition,the adsorption process was fitted well with Freundlich and Langmuir equation.
