The United Nations adopted the Sustainable Development Goals on September 25th, 2015, the sixth of which is to ensure access to clean water and sanitation for all people. When this goal was put into place, there were approximately 2.1 billion people without access to an improved water source, meaning a water source located on premises (or within a 30 min walking distance), available when needed, and free from contamination. Arsenic (As), a natural water contaminant, is abundant in many countries worldwide. Most methods used to remove (As)from water are expensive, not readily available, or not accepted culturally by different regions. The research presented in this paper looks at finding an affordable and efficient method of arsenic removal for use in developing areas. Specifically, the work focused on modifying Potters for Peace style ceramic filters, used for water filtration, by adjusting filter mix and manufacturing methods and examining various iron oxide coatings to adsorb both As(III) and As(V)from drinking water. Three ferric salts were examined (i.e., ferric nitrate, ferric sulfate, and ferric chloride), as well as zero-valent iron nanoparticles for their absorptive capacity. Two types of filters were examined 1) filters fabricated in Nicaragua and 2) filters fabricated at Saint Louis University (SLU). A 1-M ferric nitrate coating has shown the greatest reduction to date, giving the user approximately 85 uses, before As breakthrough occurred. A modified mixture for formation of a more porous SLU fabricated filter, with a 33% burnout material ratio and an ideal firing temperature of 1050 °C, has been identified. Tests are ongoing with results showing promise for moving towards the objective of a ceramic filter that removes arsenic for 150 to 600 runs without breakthrough.
