摘    要:对几种大型海藻作国吸附剂,吸附重金属废水中Pb^@+、Cu^2+、Cd^2+的吸附容量和吸附速度进行了研究,得出了它们对Pb^2+、Cu^2+、Cd^2=平衡吸附的等温曲线。实验表明,海藻的最大吸附容量在0.8~1.6mmol/g(干重)之间,吸附容量比其他种类的生物体高得多。吸附速度较快,10min内,重金属从溶液中的去除率可达到90%。实验结果还表明,大型海藻适合于发展成为高效的生物吸附材料用

关 键 词:生物吸附  重金属  海藻  废水处理

Abstract:Biozorption of heavy metals is an effective technology for the treatment of industrial. The uptake capacities and kinetics of macro alga nine of the marine macro algae for the heavy metal ions (cadmium,copper and lead )were evaluated.Equilibrium isotherms for each macro alga-heavy metal system were obtained from batch adsorption rxperiments .The maximum uptake capacities of the macro alga ranged from around 0.8 to 1.6mmol/g(DW),which were much higher than those of other tyupes of macro alga.The kinetics under the conditions studied is relatively fast.The kinetics profiles followed the typical fast then slow process in the adsorption system.About 90% of the heavy metal ions uptake occurred within 10 min and an equilibrium was reached in 40 min. The results indicated that the marine algae are suitable for the development of the effcient biosorbents to remove and recover the heavy metals from wastewater
Keywords:biosorption  removal heavy metal  marine algae  waste water treatment
