Optimization of Chromium Adsorption using Central Composite Design
Original language description
The tannery industry has traditionally been associated to environmental problems caused mainly by the discharge of effluents containing chromium. This study suggests a tannery wastewater treatment as an ecological alternative to the pollution generated by the presence of chromium in the environment, which is a highly toxic element when it is in the hexavalent form. For this purpose, a novel adsorbent obtained from waste building material (quarry stone) mixed with silica gel or activated carbon was tested to evaluate the adsorption capacity of chromium using mixtures of these materials. After an activation process the quarry stone surface has the capacity to remove efficiently chromium when it is combined with other adsorbent materials. An optimizationprocess by means of central composite design was performed to find optimum conditions of pH (8.9), quarry stone: silica gel ratio (0.75:0.25), and particle size (1895 ?m) for chromium adsorption. The water that was filtrated by the adsorb
