Batch technique was carried out for discovering adsorption of Br.G, To.B and Tr.B dyes onto [email protected] Different volume of dyes were taken from stock solution and diluted to 25 ml water at the same pH. 25 ml of these dyes were added to specific amount of [email protected] and shacked for 1 h at room temperature. The absorbance of dye solution remained were measured spectrophotometrically at maximum wavelength for Br.G, To.B and Tr.B dyes. By knowing C? (initial concentration, mg/L) and Ce (concentration of dye remains, mg/L), V is the volume of Br.G, To.B and Tr.B dyes and m is amount of [email protected] added (g). The percentage removal (%E) of dyes and capacity of [email protected] was calculated by equations:
%E=(C?-C_e)/C?×100 (1)
Q=C?EV?m (2)
