摘要：Batch process was performed to remove the reactive yellow 145 dye by using white quartz. Different operating parameters such as shaking speed, concentration of quartz, adsorbate concentration, pH values, contact time and temperature were evaluated to find maximum level of adsorption. The maximum adsorption efficiency was observed at pH 1. Increase in temperature and contact time showed positive effect on adsorption while optimum adsorption was recorded as 60 °C and 15 minutes, respectively. Moreover, concentration of the adsorbate was directly related to increase in adsorption process and the highest adsorption was achieved at 25 ppm. By contrast, increasing absorbent level showed a gradual decrease in adsorption efficiency. In a nutshell, results obtained from this study elucidate that white quartz can be considered as an efficient absorbent for the removal of reactive dye yellow 145.
