Microcrystalline cellulose (MCC) was functionalized with quaternary amine groups for use as an adsorbent to remove Congo Red dye (CR) from aqueous solution. The ultrasonic pretreatment of MCC was investigated during its functionalization. Characterization was conducted using infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The batch adsorption of the functionalized MCC was studied to evaluate the effects of dye concentration, pH of solution, temperature, and NaCl concentration on the adsorption CR. The adsorbent (FM-1) obtained using ultrasonic pretreatment of MCC under 10.8 kJ•g -1 exhibited an adsorption capacity of 304 mg•g -1 at initial pH under a dose of 0.1 g•L -1 and initial concentration of 80 mg•L -1 . After functionalization, the FT-IR and XPS results indicated that the quaternary amine group was successfully grafted onto the cellulose, the surface was transformed to be coarse and porous, and the crystalline structure of the original cellulose was disrupted. FM-1 has been shown to be a promising and efficient adsorbent for the removal of CR from an aqueous solution.

“…The process is conducted in current baths for the removal of excessive original dye, or hydrolyzed dye that has not been fixed to the fiber in the previous stages due to the low fixation rates. About 10-15% of these dyes are discarded into effluents, polluting the environment and affecting aquatic organisms [1].…”

“…The most frequently studied materials are activated charcoal [6], cellulose [7], silica [8], clay [9], zeolites [10], chitosan [11], several lignocellulosic materials, agricultural waste, such as eucalyptus [12], wheat straw [12], sugarcane bagasse [13], peanut husk [14], bamboo [15], corn grains [16] among others. The cellulose stands out for being the most abundant polysaccharide in nature, and it arouses attention specially due to its low cost [1].…”

Abstract:The cellulose matrix was characterized by FTIR, 13 C NMR, XRD, TG, SEM and applied in the removal of the reactive red RB dye in an aqueous medium, with a capacity of adsorption at a pH of 2.0, and an adsorption equilibrium time which was reached at around 200 mins. The kinetic study for the system followed the Elovich model. The adsorption isotherms for the system at temperatures of 35°C, 45°C, and 55°C were adjusted to the Langmuir, Freundlich, Sips, and Redlich-Peterson non-linear models, with a capacity of adsorption for adsorbent of 5.97 mg g , respectively. The adsorption occurred by electrostatic interactions and it was favorable and spontaneous, with the influence of temperature.

“…Another study that verified the influence of this parameter is reference [49], which also studied the adsorption of reactive red dye. This work was conducted to modify the cellulose with incorporation of quaternary ammonium groups, with the aim of adding positive charges on their surface and thus improve the adsorption capacity.…”
