BACKGROUND: Arsenic in drinking water poses serious potential health risks in more than 30 countries with total affected population of around 100 million people. The present study is devoted to the development of innovative sorbents based on zeolite materials for As(V) sorption by modifying raw materials with iron oxyhydroxide and manganese oxychloride. Natural clinoptilolite and synthetic zeolite A were modified in order to obtain improved sorption of As(V). Sorption properties of newly developed sorbentswere studied. Zeolites containing natural clinoptilolite are chosen due to relatively lowcost and their broad use in industrial production as well as characteristic large surface area.
