摘要
介绍了将羽毛非织造布作为新兴的吸附剂,经过NaOH碱溶液处理后,可去除Cu2+等重金属离子,并研究了吸附平衡线和吸附过程中如温度、时间、pH值、吸附材料的含量和被吸附的离子浓度等参数对吸附效果的影响。
Poultry feathers can be manufactured to nonwoven-webs which have enough mechanical capacity through airlaid, needle punching and thermal bonding processes. These webs, as bio-sorbents, were utilized in filtrating waste water to remove calcium, magnesium, copper and zinc ect metal ions. Treated with alkaline solutions, the webs were tested for their ability, as adsorbent, for removal of cooper ions. The paper incorporates effect of temperature, contact time, pH, amount of adsorbent, concentration of adsorbate etc. The adsorption data validates Freundtich adsorption isotherms.
