| Summary: | In the present work, an evaluation was made of clam (Polymesoda sp.), oyster (Crassostrea rhizophorae) and coral rock (Coquina) shells as bioadsorbent materials for dye removal in wastewater from the textile industry. These materials were prepared and brought to different particle diameters (300 um and less than 300 um). Subsequently, a thermal modification of the bio-adsorbent material was carried out using an initial drying at 120°C and then a calcination at temperatures: 200°C, 400°C and 600°C, to later be analyzed through different characterization techniques. (PZC, XRD, FTIR, TGA and BET). Mounts were made in the laboratory using a brilliant green dye stock solution. From this solution solutions were prepared at different concentrations (25, 50 and 75 mg/L) which were put in contact with the bioadsorbent at different pH values (between 2 and 12) with different doses of adsorbent material (between 0.2 at 0.6 g/L) and kept under constant stirring. Aliquots were taken from each experiment at different time intervals and the dye adsorption process was measured by visible ultraviolet radiation at a wavelength of 640 nm. Coquina rock was selected as the best material at a temperature of 120ºC and with a diameter greater than 300 um, with which a removal percentage of 90% was obtained in a given time between 15 and 20 minutes at pH 7. The foregoing allows us to conclude that Coquina rock is a viable and easily accessible bioadsorbent material for dye removal in textile wastewater. |
