ABSTRACT
Water is an essential resource, and as a result of demographic and industrial growth, large masses of water around the world are contaminated. Arsenic is a common and hazardous contaminant, and even though there are various removal techniques, these are expensive and provide low yields. Therefore, there is a need to find new adsorbents with better yields and lower costs. In this work 5 slags sourced from metallurgical processes were characterized and used as potential adsorbents of As (III) and As (V). Some variables such as stirring time, slag amount, arsenic concentration and their effect on arsenic removal were studied. Arsenic determination was performed by pulse differential polarography and the reduction reaction from As (V) to As (III) was optimized. Results show that the Corsa slag can remove as much as the 90% of both contaminants.
