Biosorption of heavy metals such as Pb2+, Ni2+, Cd2+, Cu2+, Cr3+ and Zn2+ by petiolar felt-sheath of palm (PFP) from contaminated water was examined. PFP was found to efficiently remove all the toxic metal ions with selectivity order of Pb2+ > Cd2+ > Cu2+ > Zn2+ > Ni2+ > Cr3+. The uptake was rapid, with more than 70% completed within 15 min. The bound metal ions were successfully desorbed and the PFP fibrous-biomass remained effective after several adsorption-desorption cycles.
研究了棕榈叶柄毡状鞘（PFP）对污染水中Pb2+、Ni2+、Cd2+、Cu2+、Cr3+和Zn2+等重金属的生物吸附作用。结果发现，PFP能有效去除所有有毒金属离子，其选择性顺序为Pb2+>Cd2+>Cu2+>Zn2+>Ni2+>Cr3+。吸附过程迅速，15分钟内完成了70%以上的吸附。结合的金属离子能够成功解吸，并且经过几次吸附-解吸循环后，PFP纤维生物质仍保持有效。
