摘要

包括重金属在内的各种污染物存在于饮用水中,造成许多健康危害。砷被研究为对人类和其他种类生命的主要有害重元素之一。砷作为地壳的天然成分存在于通过各种自然过程沉积的矿物岩石中。此外,砷还通过燃烧化石燃料、含砷农用化学品、木材防腐剂等人为方式被添加到地下水中。As III和As V是水溶液中的有毒无机形态,与癌症、砷中毒、血管疾病以及与基因、细胞、流行病学等相关的毒性有关。鉴于这些问题,对饮用水砷污染进行检测和净化势在必行。本文简要介绍了电化学方法鲁棒、快速、准确、简单等优点,以及DPV、SWV、SCP、ASV、CV等技术使电化学方法保持了传感技术的多样性和先进性。此外,还详细介绍了通过电化学过程对饮用水中砷的测定和去污,重点介绍了SWV和CV。

Assessment of toxicity and electrochemical sensing of arsenic in aqueous sources
A variety of contaminants including heavy metals present in potable water cause numerous health hazards. Arsenic is studied as one of the chief hazardous heavy elements for human beings and other categories of life. Arsenic as a natural constituent of the earth’s crust is present in mineral rocks which are deposited via various natural processes. Apart, Arsenic is also added to groundwater anthropogenically via the burning of fossil fuels, arsenical agrochemicals, wood preservatives, etc. As III and As V are the toxic inorganic forms in aqueous solution and are responsible for cancer, arsenicosis, vascular diseases, and toxicity related to genes, cells, epidemiology, etc. In view of these problems, it is obligatory to detect and decontaminate the potable water from Arsenic contaminations. In this article, a brief description has been given of the most significant electrochemical method due to its advantages like robust, fast, accurate, and less complicated, also techniques such as DPV, SWV, SCP, ASV, and CV had kept the electrochemical method as a diverse and advance technique for sensing process. In addition, the details of the determination and decontamination of Arsenic in potable water via an electrochemical process with a particular focus on SWV and CV.
