Competitive biosorption of Cd(II), Cr(III) and Ni(II) on unmodified shelled Moringa oleifera seeds (SMOS) present in ternary mixture were compared with the single metal solution. The extent of adsorption capacity of the ternary metal ions tested on unmodified SMOS was low (10-20%) as compared to single metal ions. SMOS removed the target metal ions in the selectivity order of Cd(II) > Cr(III) > Ni(II). Sorption equilibria, calculated from adsorption data, explained favorable performance of biosorption system. Regeneration of exhausted biomass was also attempted for several cycles with a view to restore the sorbent to its original state.
将未改性的带壳辣木籽（SMOS）对三元混合物中Cd(II)、Cr(III)和Ni(II)的竞争性生物吸附与单一金属溶液进行了比较。与单一金属离子相比，在未改性的SMOS上测试的三元金属离子的吸附容量较低（10-20%）。SMOS以Cd(II) > Cr(III) > Ni(II)的选择性顺序去除目标金属离子。根据吸附数据计算的吸附平衡解释了生物吸附系统的良好性能。还尝试对耗尽的生物质进行了几个循环的再生，以期将吸附剂恢复到其原始状态。
