Activated carbons were prepared from the agricultural solid wastes, silk cotton hull, coconut tree sawdust, sago waste, maize cob and banana pith and used to eliminate heavy metals and dyes from aqueous solution. Adsorption of all dyes and metal ions required a very short time and gave quantitative removal. Experimental results show all carbons were effective for the removal of pollutants from water. Since all agricultural solid wastes used in this investigation are freely, abundantly and locally available, the resulting carbons are expected to be economically viable for wastewater treatment.
活性炭由农业固体废物、木棉壳、椰子木屑、西米废料、玉米芯和香蕉髓制备而成，并用于去除水溶液中的重金属和染料。所有染料和金属离子的吸附所需时间很短，且能实现定量去除。实验结果表明，所有的碳对水中污染物的去除都是有效的。由于本研究中使用的所有农业固体废物都可免费、大量且就地获取，因此所得的碳有望在废水处理方面具有经济可行性。
