Abstract
Abstract
This paper studies the adsorbent efficiency of a modified polypropylene membrane, functionalized with carboxyl groups, to remove the As(V) from an aqueous solution. The carboxyl groups interact with arsenate in acid media by hydrogen bonds. Response surface methodology was used to optimize and evaluate parameters such as the initial concentration of As(V), contact time, and the membrane grafting degree. We found that the optimal working conditions of the membrane occurred at an initial concentration of 0.98 mg/L of As(V) and 11.8 hours of contact time, achieving a removal percentage of 68.4%. The adsorbent membrane is a potential alternative to removing arsenic from contaminated water.
