A study was carried out to verify the pH at which the surface charge of the residues of the taiti lemon peel was zero (pHPCZ) and, in artificial aqueous systems, the adsorption capacity of methylene blue by this biomass, washed with distilled water and chemically modified with NaOH 0,10 M. The experiments were carried out in triplicate, using a batch system and the methylene blue contents, adsorbed by the fibers, by UV-Vis spectrophotometry determinations. The zero load points (pHPCZ) of the two biomasses no differ statistically, presenting an average value of 5.72. The maximum adsorption rate was 99.58% (49.691 mg / g) in the modified biomass, 17.79% higher than in the washed biomass. The adsorption of methylene blue by the studied fibers was adjusted to the Freundlich isotherm model.Downloads
