“…e main advantage of these oxidized materials (SBox and Cox) comparing to other carboxylated materials prepared by our research group [14,15,20,22,[42][43][44][45] is that carboxylic acid functions in SBox and Cox are mainly from the oxidation of primary hydroxyl groups (R-CH 2 OH) of cellulose (in SB or Cel). On the contrary, when carboxylic acid groups are introduced in the Cel or SB through esteri cation reaction with cyclic carboxylic acid anhydrides, the application of esteri ed Cel or SB is limited to a pH range where the ester groups may not be easily hydrolyzed in the aqueous phase, e.g., 2-9 [46].…”

“…Agroindustrial residues mainly consist of lignocellulose biomass (LB), which can be applied in the adsorption of toxic metal species as an alternative to conventional adsorbents as activated carbons and styrene-divinylbenzene ion-exchange resins, since agroindustrial residues are cheap and e cient metal ion accumulators [14]. However, LB can be chemically modi ed to increase their attraction towards speci c pollutants or to be applied to speci c processes, enhancing their physicochemical properties, such as adsorption capacity, chemical resistance to acidic and basic media, and selectivity [15,16].…”

Batch and continuous adsorption of Co2+ and Cu2+ from aqueous solutions by oxidized sugarcane bagasse (SBox) and oxidized cellulose (Cox) were investigated. The oxidation reaction of sugarcane bagasse and cellulose was made with a mixture of H3PO4‒NaNO2 to obtain SBox and Cox, with the introduction of high number of carboxylic acid functions, 4.5 and 4.8 mmol/g, respectively. The adsorption kinetics of Co2+ and Cu2+ on SBox and Cox were modeled using two models (pseudo-first-order and pseudo-second-order) and the rate-limiting step controlling the adsorption was evaluated by Boyd and intraparticle diffusion models. The Sips and Langmuir models better fitted the isotherms with values of maximum adsorption capacity Qmax of 0.68 and 0.37 mmol/g for Co2+ and 1.20 and 0.57 mmol/g for Cu2+ adsorption on Cox and SBox, respectively. The reuse of both spent adsorbents was evaluated. Adsorption of Cu2+ and Co2+ on SBox in continuous was evaluated using a 22 factorial design with spatial time and initial metal concentration as independent variables and Qmax and effective use of the bed as responses. The breakthrough curves were very well described by the Bohart–Adams original model and the Qmax values for Co2+ and Cu2+ were 0.22 and 0.55 mmol/g. SBox confirmed to be a promising biomaterial for application on a large scale.

“…In this way, different kinds of adsorbents including inorganic-organic, bio-based, and their mixed-configuration adsorbents have been used for Ni(II) and Co(II) removal from aqueous solutions. Furthermore, there are other kinds of adsorbents called lowcost alternative adsorbents [16][17][18][19][20][21][22][23][24][25][26][27]. Recently, there is a challenge between various adsorbents in view of adsorption capacities and economic issues.…”

A novel polyvinyl alcohol/alginate/zeolite nanohybrid adsorbent for the adsorption of Ni(II) and Co(II) metal ions was prepared by the casting method. The prepared adsorbent was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy as well as Barrett-Joyner-Halenda and Brunauer-Emmett-Teller analyses. The optimum adsorption conditions in terms of content of zeolite nanoparticles, adsorbent dosage, and initial pH were determined. The kinetic data for both ions were well described by the double-exponential kinetic model. The obtained Langmuir maximum adsorption capacities of Ni(II) and Co(II) metal ions were 81.51 and 79.58 mg g -1 , respectively. The adsorption/ desorption experiments showed a good performance after 5 cycles of adsorption.

“…24 The aim of this study was to carry out a thoroughly investigation of the adsorption of Cu(II) ions by AL from EHR, 25 including the adsorption kinetic, adsorption isotherm 26 and factors which could make a difference to the adsorption of Cu(II) ions onto AL such as pH, reaction temperature, reaction time and initial concentration of Cu(II) ions. 27 The relationship between the adsorption capacity and adsorption mechanisms was studied by Langmuir and Freundlich isotherms models. 28,29 Lignin from EHR of corn stalks in cellulosic ethanol process could be modied and then used to remove heavy metal ions which can maximize the economic value of the residues.…”
