“…The Methylene Blue adsorption capacity for various lignocellulosic materials found in the literature was compared to the coffee residues adsorption capacity estimated in the present work (see Table 1). The adsorption capacity of the coffee residue was better than the adsorption capacity of other waste biomass such as peanut husk [14], turbinaria turbinate alga [12], and wheat straw. The coffee residues adsorption capacity found in the present work was close to the …”

“…Hence, it is of pivotal importance thence of low-cost substitute absorbents to replace activated carbons. Various types of untreated biomass have been reported to have a use in dye removal: peanut husk [11], palm kernel fibre [11], Turbinaria turbinate alga [12], graphene [13], defatted jojoba [14] and sugar bet pulp [15]. Further, numerous pretreated lignocellulosic materials are used to remove dyes in water and wastewater.…”

This paper contributes to the Industrial Ecology Concept by using a common urban solid waste, i.e., coffee residues, to clean industrial wastewaters polluted by basic dyes, e.g., Methylene Blue. For the data from the continuous fixed-bed column system, two common models, namely (a) Bohart and Adams and (b) Clark were implemented. The Bohart and Adams capacity was up to N = 46,166 mg·L -1 or q 0 = 104.5 mg·g -1 for bed-depth 15 cm, initial dye concentration 800 mg·L -1 and flow rate 20 mL·min -1 . The results revealed that the Methylene Blue is fairly adsorbed on coffee residues. Consequently, this process can be applied as a low cost technique for cleaning basic dyes from the aquatic environment.

“…The adsorption kinetic studies were used to determine the adsorption behavior such as the adsorption type, rate and the capacity of the adsorption of the system (Malekbala et al, 2012). In order to investigate the adsorption behavior, three kinetic models pseudo first order, second order and intraparticle diffusion models were used.…”

The present study investigates the ability of formaldehyde treated Simarouba glauca seed shell powder for removal of methylene blue (MB) from aqueous solutions. Batch adsorption studies were carried out under various experimental conditions such as agitation time, dye concentration, adsorbent dose and pH. The adsorbent was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), XRD, BET and CHNS analysis. The adsorption data were analysed using Langmuir, Freundlich, Temkin and Dubinin -Radushkevich isotherms. Equilibrium data fitted well to Langmuir isotherm with maximum adsorption capacity of 111.1 mg g -1. Adsorption kinetic data were verified using pseudo first order, pseudo second order and Intraparticle diffusion model. The kinetic data were found to fit well with pseudo second order model.

Chitosan graft poly(acrylic acid-co-2-acrylamide-2-methyl propane sulfonic acid) (CTS-g-P(AA-co-AMPS)) hydrogel is prepared and used to remove methylene blue (MB) and rhodamine B (RB) mixed dyes from aqueous solutions. The effect of adsorption conditions, including the initial concentrations of dye solutions, contact time, initial pH values, ionic strength, and the adsorbent dosage, on the adsorption capacities is investigated. The maximal adsorption capacity for MB and RB is 936.0 and 556.9 mg/g, respectively. The adsorption isotherms of the mixed dyes are discussed using the extended Langmuir (EL) and the extended Freundlich (EF) isotherm equations. It indicates that the adsorption of both dyes is in good agreement with the extended Freundlich isotherm. Meanwhile, the adsorption processes of both dyes are spontaneous. Adsorption kinetics is in accordance with the pseudo-secondorder kinetic equation. It is concluded that the available adsorption sites are shared by both kinds of the dye molecules. The difference of the maximal adsorption capacities of the two dyes is due to their different affinity to the adsorbent.
