Adsorption of brilliant green

Adsorption of brilliant green, toluidine blue and trypan blue dyes onto [email protected] was investigated by Batch technique. Known concentration 25 ml of dye solution in different tubes at the same pH with Constant amount of [email protected] was added for pumping 1h. The residual dye solution was measured by UV-vis spectrophotometer at ? max specializes for Br.G, To.B and Tr.B dyes to get absorbance. 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 gram added from [email protected] 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)
