The use of ceramic waste to treat dye waste water has been studied. Ceramic tile waste from construction site was washed, dried, and ground in a ball mill.

摘要

The use of ceramic waste to treat dye waste water has been studied. Ceramic tile waste from construction site was washed, dried, and ground in a ball mill. After sieving, 120 mesh undersize material was dried at 1300C for 6 h to remove the water content. The resultant powder was used as the adsorbent. 1 gm of adsorbent was added to 100 ml of 5 ppm methylene blue dye solution and stirred on a magnetic stirrer at 500 rpm under ambient conditions. The change in absorbance was recorded on Ultraviolet (UV) Spectrophotometer at 15-min intervals for 90 min. The maximum dye removal efficiency was 90.74%. The system exhibited pseudo-second-order kinetics. The effect of particle size on the adsorption capacity was studied too. It was found that the adsorption capacity decreased with increasing particle size but remained constant above 1 mm. The used adsorbent was regenerated by heating it to a temperature of 5500C in an oven for a period of 1 h. The above experiments were performed on different tile grades and the efficiencies were compared. The characterization of the powders was done by the SEM (Scanning Electron Microscopy). The results indicate that using ceramic tile waste can be effectively used as an adsorbent for dye waste water treatment. It also provides an environmentally friendly way of recycling ceramic waste.
