Abstract

Arsenic contamination resulted from the rapid development of various industries affecting the water resource quality worldwide. Because of the risk of arsenic exposure to both the environment and humans, specific arsenic wastewater treatment is required to meet the anticipated water quality standards. A better understanding of current technologies is crucial while addressing the limitations in order to develop more effective methods for arsenic removal. This work presents updates on adsorption by metal nanoparticles, electrocoagulation, photocatalysis, and membrane methods including nanofiltration, ultrafiltration, reverse osmosis, and microfiltration, their advantages and limitations as well as the future direction of the wastewater treatment industry. Recent strategies using combination technologies show promising potential and present windows of opportunity to be tested in real life and large scale. Further research on these technologies is still required to assess the full potential of these technologies for arsenic removal able to shift the paradigm towards sustainability of tomorrow.

回顾：废水除砷的最新技术

砷污染是由于各种工业的快速发展影响了全球的水资源质量。由于砷对环境和人类都有暴露风险，因此需要对含砷废水进行特殊处理，以达到预期的水质标准。为了开发更有效的除砷方法，更好地了解当前技术的局限性至关重要。本著作介绍了金属纳米颗粒吸附、电凝、光催化和膜方法（包括纳滤、超滤、反渗透和微滤）的最新进展、其优势和局限性以及废水处理行业的未来发展方向。采用组合技术的最新战略显示出巨大的潜力，为在现实生活中进行大规模测试提供了机会之窗。仍需对这些技术进行进一步研究，以评估这些技术在除砷方面的全部潜力，从而转变模式，实现未来的可持续发展。
