摘要
砷在自然界中普遍存在,砷酸盐及亚砷酸盐具有很强的毒性,进入环境中会对人们的生产生活造成很大的危害.综述了当前国内外砷处理技术的研究现状,介绍了铁硫化合物除砷、纳米铁(nZVI)吸附除砷、二氧化钛吸附除砷的技术条件和除砷效果,并对砷治理的发展趋势及应用前景进行了分析和展望.
Abstract
Arsenic is ubiquitous in nature.Arsenic and arsenite are highly toxic.Entering the environment can cause great harm to people's production and life.In this paper,the research status of arsenic treatment technology at home and abroad was reviewed.The technical conditions and effectivenesses of the removal of arsenic by Fe-sulfur compounds,nano-iron adsorption and titanium dioxide adsorption were introduced.The development trend and application prospects of arsenic treatment were analyzed.
