Mansonia wood sawdust is applied as a biosorbent for the removal of copper and lead ions from single and binary aqueous solution. The effect of solution pH, electrolyte, metal ion competition and temperature were examined to obtain insight of its application for industrial waste water treatment. The Langmuir isotherm provided a better fit to experimental data for lead ion sorption with a higher monolayer capacity, while copper ion sorption was best described by the Freundlich and BET isotherms. The combined effect of adsorbing one metal ion in the presence of the other metal ion reduced the adsorption capacity of either metal ion. In a binary solution, removal of lead ions in the presence of copper ions followed the Langmuir isotherm model while the removal of copper ions in presence of lead ions followed both the Langmuir and BET isotherm models.
曼索尼亚木屑被用作生物吸附剂，用于从单一组分和双组分水溶液中去除铜和铅离子。考察了溶液 pH 值、电解质、金属离子竞争和温度的影响，以了解其在工业废水处理中的应用。对于铅离子的吸附，Langmuir 等温线提供了更好的拟合实验数据，具有更高的单层容量，而铜离子的吸附则最好由 Freundlich 和 BET 等温线来描述。在存在另一种金属离子的情况下，吸附一种金属离子的共同作用降低了任一种金属离子的吸附容量。在二元溶液中，在存在铜离子的情况下去除铅离子遵循 Langmuir 等温线模型，而在存在铅离子的情况下去除铜离子则遵循 Langmuir 和 BET 等温线模型。
