Adsorption of brilliant green
Adsorption of brilliant green, toluidine blue and trypan blue dyes onto SVTPUP@ZnONPs was investigated by Batch technique. Well- Known concentration 25 mL of dye solution in different tubes at the same pH with Constant amount of SVTPUP@ZnONPs was mixed 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 (volume of Br.G, To.B and Tr.B dyes, L) and m (gram added from SVTPUP@ZnONPs). The percentage removal (%E) of dyes and capacity of SVTPUP@ZnONPs was calculated by equations:
%E=(C?-C_e)/C?×100 (1)
Q=C?EV?m
