摘要

《2030年议程》包含17项可持续发展目标（sdg），其中一些目标支持循环和可持续的生产和消费，如可持续发展目标11和12。主要目标之一也是减少和管理废物。在循环生物经济方法下，农业废弃物是一个具有高潜力的新价值产品的重大障碍。再利用和再循环对循环经济至关重要，有可能提高废物价值并减少对环境的危害。利用生物废物，包括纸浆、残茬、种子、叶子和甘蔗渣，来合成纳米粒子是一种经济、低能耗和环保的方法。方法为了解决废水处理问题，近年来的研究主要集中在从农业废弃物中开发高效环保的生物吸附剂上。因此，寻找当地可获得的农业副产品来去除染料和重金属变得更加重要。利用纳米技术是提高废水处理和修复的一种创新和可靠的方法。这包括制造纳米粒子、混合纳米复合材料，以降解或去除废水中的污染物，因为它们改善了表面特性和化学反应性。重大发现农业废弃物管理的研究最近有了显著的增长，在过去的四年里发表了4688篇论文，其中77%是研究论文，23%是评论论文。本文综述了提高生物吸附剂效能的方法，以及为最大限度地去除污染物而对吸附剂进行改性的最新进展。纳米生物吸附剂在室温下的最大吸附量大于400 mg/g。根据数据，BET/N2比表面积在1.311 ~ 23.9 m2/g之间变化。结果表明，该方法对污染物的去除率在85% ~ 99.0%之间。这项研究将有助于开发更有效的污染物去除系统，缩小实验室结果与工业应用之间的差距，并应对其缓解措施带来的挑战。

Strategic engineering and functional mechanism elucidation of advanced materials in detoxification of contaminated water matrices

Background

The 2030 Agenda contained 17 Sustainable Development Goals (SDGs), some of which support circular and sustainable production and consumption such as SDGs 11 and 12. One of the primary goals is also waste reduction and management. Agricultural waste is a significant obstacle with high potential for new value products under the circular bioeconomy approach. Reuse and recycling are essential to the circular economy, potentially enhancing waste value and reducing environmental harm. Using bio-waste, including pulp, stubble, seeds, leaves, and bagasse, to synthesise nanoparticles is an economical, low-energy, and ecofriendly method.

Methods

In order to solve wastewater treatment issues, recent research has concentrated on developing efficient and environmentally friendly biosorbents from agricultural waste. Finding locally accessible agricultural byproducts to remove dyes, and heavy metals has therefore become more crucial. An innovative and dependable way to enhance wastewater treatment and remediation is using nanotechnology. This includes making nanoparticles, hybrid nanocomposites in degrading or getting rid of contaminants from wastewater because of their improved surface characteristics and chemical reactivity.

Significant Findings

Research on agricultural waste management has had a significant increase recently, with 4688 publications published over the previous four years—comprising 77 % research articles and 23 % review papers. This review focus towards the methods to increase the effectiveness of biosorbents, recent progress made in the modification of adsorbents for the maximum removal of remove contaminants. The maximum adsorption capacities for nanobiosorbents at room temperature were found to be greater than 400 mg/g. According to the data, the BET/N2 specific surface varies from 1.311 m2/g to 23.9 m2/g. It was found that percentage removal of pollutants ranges from 85 % to 99.0 %. This study will contribute to developing more effective pollutant removal systems by bridging the gap between laboratory results and industrial applications and also the challenges with their mitigation measures.
