“…It was also found that with the increase in the carbon content in biochar, biosorption capacity-q eq2 also increased. This relationship was also observed for biocomposites produced from different cellulosic substrates (barley husk, peanut shells and sawdust), i.e., biosorbents with a higher percentage of carbon showed higher capacities [9].…”

“…Gokulan et al (2019) showed that the sorption of dye by the biochar from green seaweed Ulva lactuca was rapid and occurred within the first hour, which was caused by easily available binding groups (functional groups) on biochar surface [37]. The kinetics of metal ions biosorption is generally described by the pseudo-first (Equation (3)) and the pseudo-second order model (Equation (4)) [7,9,24,33,37]:…”

“…where qeq1, qeq2 and qt are the amounts of adsorbed metal ions on the biosorbent at equilibrium and at time t (mg g −1 ), and k1 and k2 are the rate constants of the pseudo-first (min −1 ) and pseudo-second order model of biosorption (g mg −1 min −1 ). From the linear form of Equations (3), (Equation (5)) and (4) (Equation (6)) it was possible to determine the parameters of qeq1, k1, qeq2 and k2, respectively: The kinetics of metal ions biosorption is generally described by the pseudo-first (Equation (3)) and the pseudo-second order model (Equation (4)) [7,9,24,33,37]:…”

The multi-elemental composition, surface texture and morphology of biochar, produced by pyrolysis at 300, 350, 400 and 450 °C from freshwater macroalga Cladophora glomerata, as a biosorbent of toxic metals was examined with Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FT-IR) techniques. It was found that the yield of pyrolysis was inversely proportional to temperature: for 300 °C it was 63%, whereas for 450 °C—47%. The proximate analysis revealed that also biochar’s moisture and volatile matter was inversely proportional to temperature. The content of ash increased with temperature. All biochars were characterized by a similar total pore area of about 20 m2 g−1. FT-IR analysis showed that all biochars peaked at 3500–3100 cm−1 which was attributed to O–H stretching of the hydroxyl groups, at 2850–2970 cm−1, stretching vibrations of C–H bonds in aliphatic CH2 and CH groups, at 1605 cm−1, stretching vibrations from C=C of aromatics, at 1420 cm−1, bending oscillations from CH2, at about 1111 cm−1, stretching vibrations of Si–O, at 618 cm−1, vibrations from Fe–O bonds, and at 475 cm−1—Si–O–Si deformation vibrations. The biosorption properties of biochar towards Cr(III) ions were examined in kinetic studies. The biosorption capacity of biochar increased with an increase of pyrolysis temperature: the highest was for biochar obtained at 450 °C—87.1 mg Cr(III) g−1 and the lowest at 300 °C—45.9 mg g−1. Cladophora biochar also demonstrated a good ability to simultaneously remove metal ions from a multi-metal system, e.g., wastewater. The removal efficiency for Cr(III) was 89.9%, for Cu(II) 97.1% and for Zn(II) 93.7%. The biochar derived from waste-freshwater macroalgae can be a potent and eco-friendly alternative adsorptive material.

“…Hameed and El-Khaiary [8] successfully used pumpkin seed hulls for the removal of methylene blue from aqueous solutions. Peanut shells were already effectively used as an adsorbent for dye [9] and heavy metals [10].

Agricultural waste products including sunflower seed hulls, pumpkin seed shells, walnut shells and peanut shells were used as low-cost adsorbents for the removal of 2,4,6-trichlorophenol (TCP) from aqueous solutions. The effects of adsorbent dosage, pH and ionic strength on the adsorption of TCP were investigated. The results showed that the adsorption of TCP was pH dependent and increased upon increasing the ionic strength of the solution. The adsorption kinetics was found to follow a pseudo-second order kinetics. The equilibrium adsorption data were fitted to the Langmuir, Freundlich and Sips isotherms and the best results were achieved with the Freundlich model. The desorption of TCP using deionized water, water/methanol mixture or 5% sodium hydroxide was also studied. The results suggest that the tested materials may be used as an effective adsorbents without any treatment or any other modification for removal of TCP from the aqueous medium.

“…To further understand the adsorption mechanism of the CL powders toward the investigated dyes, three kinetic models including the pseudo-first order, pseudo-second order, and intraparticle diffusion kinetic models were considered. These kinetic models are expressed as Equations (6)–(8), respectively [57,58,59,60,61]. lnfalse(Qe−Qtfalse)=lnQt−k1t tQt=1k2Qe2+tQe Qt=kpt1/2+C where k 1 (g·mg −1 ·min −1 ) and k 2 (g·mg −1 ·min −1 ) are the rate constants of the pseudo-first order and second order models; Q e (mg·g −1 ) and Q t (mg·g −1 ) are the adsorption capacities at equilibrium and at time t (min); h (mg·g −1 ·min −1 ) is the initial adsorption rate of the pseudo-second order kinetics; k p (g·mg −1 ·min −1 ) is the rate constant of the intraparticle diffusion model; and C is a constant characterizing boundary layer thickness.…”

As a natural polymer, leather and its associated industries are known to be the leading economic sector in many countries. However, the huge amounts of leather waste generated from the leather industry causes severe environmental pollution. Herein, cow leather (CL) powders were prepared using a homemade machine and used as a low-cost adsorbent for the effective removal of reactive dyes from wastewater. The as-prepared CL powders exhibited dot-like, rod-like, and fiber-like morphologies. A Fourier transform infrared analysis and an x-ray diffraction analysis demonstrated that the CL powders retained the main structure of the protein contained in it. In addition, an improvement in thermal stability was also observed for the CL powders. Dye adsorption experiments indicate that the CL powders showed the highly effective removal of C.I. Reactive Red 120 (RR120), C.I. Reactive Yellow 127 (RY127), and C.I. Reactive Blue 222 (RB222) with the adsorption capacity of 167.0, 178.9, and 129.6 mg·g−1, respectively. The Langmuir, pseudo-second order, and intraparticle diffusion models could well depict the adsorption equilibrium and kinetics of CL powders toward the investigated reactive dyes. The as-prepared CL powders can be used as a potential adsorbent in the treatment of dye contaminated wastewater. Future studies will mainly focus on the application of the adsorbed CL powders for the pigment printing of textile materials.
