“…Pure cellulose has very low adsorption capacity, where the removal of trace level of metals is impossible; however, chemical modification can improve adsorption capacities. Studies have reported that introducing functional groups such as a carboxyl, amine, sulfur, and amino groups onto the surface of cellulose can improve the adsorption ability of cellulose 9–17 …”

Heavy metals pollutants are nonbiodegradable and their bioaccumulation results in detrimental environmental consequences. Therefore, it is important to effectively remove toxic heavy metal waste from industrial sewage. Thus, the main goal of this research is to synthesize an ideal cellulose‐based adsorbent from palm‐based waste materials (agro waste) in order to be utilized in real‐life practical applications with low cost as such removing common toxic heavy metals from industrial effluents. A poly(methyl acrylate) grafted palm cellulose was synthesized via a free‐radical initiation process, followed by an oximation reaction to yield poly(hydroxamic acid) ligands. The adsorption capacity (qe) of poly(hydroxamic acid) ligands for metal ions such as copper (Cu2+), iron (Fe3+), and lead (Pb2+) were 325, 220, and 300 mg g−1, respectively at pH 6. In addition, the X‐ray photoelectron spectrometry results are to be proved the binding of metal ions, for instance, Cu(II) ions showed typically significant BEs of 932.7 and 952.0 eV corresponding to the Cu2p3/2 and Cu2p1/2 species. The heavy metal ions adsorption followed a pseudo‐first‐order kinetic model pathway. The adsorption capacity (qm) is also derived from the Langmuir isotherm linear plot, which does not showed good correction coefficients. However, the results were correlated to the Freundlich isotherm model, where the R2 value showed significance (>0.98), indicating that multiple layer adsorption occurs on the synthesized ligand. The synthesized polymeric ligand is an excellent adsorbent for the removal of heavy metals from the industrial wastewater. In addition, the metal analysis results showed that about 98% removal of copper and iron ions from electroplating wastewater including lead, nickel, and chromium can be removed up to 85–97%.

“…7 Typical examples of biopolymers used for the removal of methylene blue from aqueous solutions include carboxymethyl cellulose, 8 immobilized microcrystalline cellulose, 9 chitosan/sepiolite composite, 10 chitin, 11 magnetic carboxymethyl cellulose microspheres, 12 polyacrylamide-sodium alginate microspheres, 13 starch, 14 graphene oxide/calcium alginate composites 15 and activated biomass/alginate beads. 16 To date, graphene oxide (GO), the oxidized form of graphite, 17 has been widely and intensively used as a promising adsorbent for the removal of organic molecules from aqueous solutions. Its unique physicochemical and morphological properties such as large surface area, abundant oxygencontaining functional groups 18 enable it to be used as an alternative adsorbent for dyes and heavy metals.…”

“…During the dyeing process, over 12%–15% of dyes are being wasted as effluents by the industries. Such industrial activity contaminates the water, which mainly affects the photosynthesis of aquatic lives 2,3 . In addition, such contaminants and their degradation products are mutagenic, teratogenic, and carcinogenic.…”

“…Among these techniques, adsorption is the most effective and economically viable process because of its simple design, easy operation, and low cost investment, which does not produce destructive byproducts 12 . There are several reports available for porous and nonporous solid materials including carbon material, silica‐based material, zeolite, and so forth which work as adsorbent 3 . However, these methods have some limitations such as high cost, requirement of high temperature and expensive regeneration 13 .…”

Agaraldehyde and chitosan (CHI) functional beads as dye adsorbent were prepared under aqueous medium under ambient temperature and used for removing seven dyes from aqueous solutions. The resulting porous CHI‐Aald (R‐Aald‐CHI) bio‐beads were characterized by X‐ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscope. The dye removal efficiency was studied using seven dyes (amido black [AB], bromophenol blue, crystal violet, bismarck brown, cotton blue, methyl orange, methylene blue), but detail study was done on AB. AB adsorption was followed the Langmuir‐isotherm and pseudo‐second order kinetics. The effects of adsorption parameters were investigated, and maximum AB 1506 mg/g was adsorbed under the optimum conditions. The linear and nonlinear forms of Langmuir and Freundlich isotherms and two kinetic models pseudo‐first‐order and pseudo‐second‐order were studied. The results show that adsorption follow both isotherm model while for kinetics of adsorption follow pseudo‐second‐order. The results of this work showed that R‐Aald‐CHI was encouraging adsorbent to remove dyes from wastewater, especially AB.
