Biosorption is an emerging technique for water treatment utilizing abundantly available biomaterials (especially agricultural wastes). Among several agricultural wastes studied as biosorbents for water treatment, coconut has been of great importance as various parts of this tree (e.g. coir, shell, etc.) have been extensively studied as biosorbents for the removal of diverse type of pollutants from water. Coconut-based agricultural wastes have gained wide attention as effective biosorbents due to low-cost and significant adsorption potential for the removal of various aquatic pollutants. In this review, an extensive list of coconut-based biosorbents from vast literature has been compiled and their adsorption capacities for various aquatic pollutants as available in the literature are presented. Available abundantly, high biosorption capacity, cost-effectiveness and renewability are the important factors making these materials as economical alternatives for water treatment and waste remediation. This paper presents a state of the art review of coconut-based biosorbents used for water pollution control, highlighting and discussing key advancement on the preparation of novel adsorbents utilizing coconut wastes, its major challenges together with the future prospective. It is evident from the literature survey that coconut-based biosorbents have shown good potential for the removal of various aquatic pollutants. However, still there is a need to find out the practical utility of such developed adsorbents on commercial scale, leading to the superior improvement of pollution control and environmental preservation.
生物吸附是一种新兴的水处理技术，利用丰富的生物材料（特别是农业废物）。在被研究为水处理用生物吸附剂的几种农业废物中，椰子因其作为树的各个部分（如椰壳纤维、椰壳等）被广泛研究为从水中去除各种类型污染物的生物吸附剂而具有重要意义。基于椰子的农业废物作为有效的生物吸附剂引起了广泛关注，因为它们具有低成本和去除各种水生污染物的显著吸附潜力。在这篇综述中，从大量文献中编译了广泛的基于椰子的生物吸附剂列表，并展示了文献中可用的它们对各种水生污染物的吸附能力。这些材料具有丰富的可用性、高生物吸附能力、成本效益和可再生性，是水处理和废物修复的经济替代品的重要因素。本文对用于水污染控制的基于椰子的生物吸附剂进行了综述，强调和讨论了利用椰子废物制备新型吸附剂的关键进展、主要挑战以及未来前景。从文献调查中可以明显看出，基于椰子的生物吸附剂在去除各种水生污染物方面显示出了良好的潜力。然而，仍然需要在商业规模上找出这些开发的吸附剂的实际应用，从而更好地改善污染控制和环境保护。
