| description | Dyes are widely used in different industrial dying purpose such as textiles, food, cosmetics and paper printing, Leather etc. Among those dyes, Methylene blue (MB) is the most common one which isused in various industries. Moreover, Tea is one of the most popular beverages and about 3.5 million tons of tea was consumed annually in the world (Kumar and al., 2005). In this study, Tea Waste (TW)has been used as an absorbent for the removal of MB. Varying experimental conditionsare tested at different ranges such asadsorbent dosage,pHandcontact time. Adsorption equilibrium of tea waste reached within 2 hours for methylene blue concentrations of 30ppmand pH value of 4. The efficiency of dye extraction increased with increasing time and the decreasing of pH value of adsorption. The maximum removal efficiency was found on the addition of 0.7gm doses. It removed maximum dye at pH4 in which removal efficiency was 97.87%. On the other hand, that the percentage of removal efficiency maximum when the testing time 120 min.The results revealed that tea waste appears as a very low-cost adsorbent for the removal of methylene blue. |
