EQUILIBRIUM AND ISOTHERMAL STUDIES ON REMOVAL OF BISMARCK BROWN DYE USING MAGNESIUM NANOPARTICLES BY ADDING BACTERIAL CULTURE TO NANOPARTICLES
Abstract
The research had been done on the removal of dyes from wastewater using low-cost and eco-friendly biosorbent options. A cheap and effective biosorbent for removing Bismarck Brown dye from aqueous solutions using magnesium nanoparticles by adding pseudomonas Aeruginosa culture to it, which is widely accessible. The equilibrium stirring time for BB dye sorption is 40 minutes. The optimum dosage for sorption is 2.6 g/L. Maximum extent of sorption is noted at pH = 7. The maximum uptake capacity of 6.6153 mg/g is obtained at 303 K. The experimental data are well represented by Langmuir (R2 = 0.994), Freundlich (R2 = 0.988) and Temkin (R2 = 0.994) isotherms.
