Abstract：
Presence of heavy metal (HM) ions in wastewater have emerged as among the most prominent issues for improving water quality and reducing it\'s consequences for the environment, animal and public health. This paper mainly focuses on the remediation of HM ions from wastewater utilizing the relatively inexpensive and widely accessible agricultural waste-Sugarcane Bagasse (SCB). For this, a brief understanding of HMs was discussed (by understanding the sources and toxicity of HM, advantages and shortcomings of conventional processes). Apart from that, to understand the potential of SCB, this review would provide vital information on employing SCB biosorbent in natural and modified forms for HM removal. Therefore, various ways of SCB modifications (including physical, chemical, and composite formation), essential optimal operational conditions (solution pH, dosage of biosorbent, initial metal concentration, contact time, agitation speed, temperature, suitable isotherm and kinetic model) and involving adsorption mechanism were also studied. Finally, significant study gaps were identified to facilitate future research since SCB has been confirmed as a potential bio-adsorbent for removing HM ions.
摘要：
废水中重金属（HM）离子的存在已成为改善水质和减少其对环境的影响的最突出问题之一。动物和公共卫生。本文主要研究利用相对便宜且可广泛使用的农业废物甘蔗渣（SCB）对废水中的HM离子进行修复。为此，讨论了对HM的简要了解(通过了解HM的来源和毒性，传统工艺的优点和缺点)。除此之外,为了了解SCB的潜力，这篇综述将提供有关使用天然和改良形式的SCB生物吸附剂去除HM的重要信息。因此,SCB修改的各种方式(包括物理、化学,和复合地层)，基本最佳操作条件(溶液pH，生物吸附剂的用量，初始金属浓度,接触时间,搅拌速度,温度,还研究了合适的等温线和动力学模型）以及涉及的吸附机理。最后,由于SCB已被确认为去除HM离子的潜在生物吸附剂，因此确定了重要的研究空白以促进未来的研究。
