Sequestration of Brilliant Green Dye by Coriander Leaf: Isotherm and Kinetic Studies
نویسندگان
چکیده
Adsorption process has been performed to investigate the potentiality of coriander leaf sequester brilliant green (BG) dye from aqueous phase. Coriander 75-micron size characterized by SEM, BET, FTIR etc. In present study, emphasis given on removal BG under different conditions viz. dose biomaterial (10.0 - 100.0 mg), pH (2.0 12.0) and concentration mg/L) Taguchi optimization. The batch experiments have conducted at 25 ℃ with stirring speed 120.0 rpm. kinetic study is two temperatures, 30 40 ℃. adsorption for sequestration followed pseudo-2nd order kinetics (R2 = 0.99). also reveals that Freundlich isotherm best fitted 0.96) model. capacity 68.49 mg/g overall efficiency above 80.0 %.
