Industrialization and urbanization have led to the release of increasing amounts of heavy metals into the environment. Metal ion contamination of drinking water and waste water is a serious ongoing problem especially with high toxic metals such as lead and cadmium and less toxic metals such as copper and zinc. Several biological materials have attracted many researchers and scientists as they offer both cheap and effective removal of heavy metals from waste water. Therefore it is urgent to study and explore all possible sources of agrobased inexpensive adsorbents for their feasibility in the removal of heavy metals. The objective was to study inexpensive adsorbents like various agricultural wastes such as sugarcane bagasse, rice husk, oil palm shell, coconut shell, and coconut husk in eliminating heavy metals from waste water and their utilization possibilities based on our research and literature survey. It also shows the significance of developing and evaluating new potential biosorbents in the near future with higher adsorption capacity and greater reusable options.
工业化和城市化导致越来越多的重金属释放到环境中。饮用水和废水的金属离子污染是一个严重的持续问题，尤其是铅和镉等高毒性金属以及铜和锌等低毒性金属。几种生物材料吸引了许多研究人员和科学家，因为它们能以低成本有效去除废水中的重金属。因此，迫切需要研究和探索所有可能的农业基廉价吸附剂来源，以评估其去除重金属的可行性。目的是基于我们的研究和文献调查，研究甘蔗渣、稻壳、油棕壳、椰壳和椰 husk 等各种农业废弃物等廉价吸附剂在去除废水中重金属方面的作用及其利用可能性。它还表明了在不久的将来开发和评估具有更高吸附容量和更多可重复使用选项的新型潜在生物吸附剂的重要性。 （注：原文中“椰 husk”未准确表述，可能影响理解）
