Abstract

Stains are extremely utilized in various industrial dying aims like materials, food, cosmetics, paper print, Leather, etc. Among those stains, Methylene blue is the most typical one that is utilized in different industries. Furthermore, Tea is one of the most popular beverages and about 3.5 million tons tea has been used yearly in the world (Kumar and al., 2005). In this investigation, Tea Wastage has been employed as an adsorbent for the deduction of Methylene blue. Differing empirical situations have experimented in various rang like absorbent dose, PH, and contact time. Absorbent tea waste balance aimed in two hours for methylene blue concentrations of thirty ppm and pH amount of four. The performance of stain exploitation improved by raising time and the diminishing PH amount of absorption. The highest reduction performance has been found in the expansion of 0.7gm dose. It dismissed the highest stain at PH 4 the removal performance has been 97.87percent. Furthermore, the percent of reduction performance is highest while the test time is 120 minutes. The outcomes demonstrated that tea wastage appears as a so low-cost absorbent for the methylene blue reduction.
