“…However, the MRES has exhibited almost 100% DR for MB up to 600 mg/L and for RR‐120 up to 300 mg/L, respectively. It is known that the dye concentration in textile industry wastewater varies between 10 and 250 mg/L depending on the type of dye and the performed process 65 . In a wide concentration range for both basic and acidic dyes, these high DR ratios make MRES an advantageous adsorbent.…”

This study reports the synthesis and characterization of a new amphoteric resin, which can be used for the removal of both cationic, methylene blue (MB) and anionic dyes, reactive red‐120 (RR‐120). The amphoteric resin was characterized by ATR‐FTIR, SEM–EDX, TGA/DTA, DLS, BET analysis and also its surface pHpzc was determined. The prepared resin has micro porous structure and its particle size was at the nano level. The prepared amphoteric resin showed high removal affinity for MB in both acidic and basic medium, while for RR‐120 high removal affinity in acidic medium. Moreover, it was observed that the amphoteric resin has exhibited almost 100% dye removal up to 600 ppm for MB and up to 300 ppm for RR‐120, respectively. The adsorption behavior of both dyes on the amphoteric resin is in agreement with the Langmuir isotherm and the pseudo‐second order kinetic model and also electrostatic interaction is dominant in adsorption. Its capacity was slightly low for the MB than that of the commercial activated carbon, but higher for the RR‐120. Furthermore, it was observed that the amphoteric resin almost did not lose its high removal efficiency in the concentrated matrix environment for both dyes. After five repeated adsorption–desorption cycles, the high removal efficiency of the resin for the MB (almost 100%) unchanged, but for the RR‐120 decreased to 83%.

“…The study of PBNPs and ionic organic pollutants, such as dyes, has been largely limited to PBNP-magnetic composites for the purpose of dye collection and recycling. The interaction between the cationic and anionic organic pollutants (methylene blue and reactive red, respectively) and magnetic activated carbon (MAC) nanoparticles is principally a function of pH (Abuzerr et al 2017 ). Those authors observed that methylene blue was optimally removed from aqueous solution at pH 10, whereas reactive red was most efficiently removed at pH 5.5.…”

Nanoparticles are abundant in the subsurface, soil, streams, and water bodies, and are often a critical control on elemental speciation, transport and cycling in the natural environment. This review provides an overview of pyrolyzed biomass-derived nanoparticles (PBNPs), their surface properties and reactivity towards aqueous species. We focus specifically on biochar-derived nanoparticles and activated carbon-derived nanoparticles which fall under our classification of PBNPs. Activated carbon-iron (nano)composites are included in some instances where there are significant gaps in literature because of their environmental relevance. Increased use of activated carbon, along with a resurgence in the manufacture and application of biochar for water treatment and soil amendment, has generated significant concerns about the mobility and toxicity of PBNPs derived from the bulk material in environmental applications. Recent examples are discussed to highlight current progress in understanding the influence of PBNPs on contaminant transport, followed by a critical discussion of gaps and future research directions.

“…Further slowing of the adsorption rate is probably due to the gradual saturation of the adsorption and adsorption active sites by the dye molecules, so increasing the contact time will not affect the adsorption capacity. Therefore, the final contact time for all experiments was 90 min [46][47][48].…”

In the present study, the study and fabrication of inorganic organic nanocomposites with Guar gam and Carboxy methyl cellulose biopolymer substrates. The synthesis nanocomposite of CMC/GG/CuO-3 is biodegradable and biocompatible, and also has a significant efficiency in removing malachite green (MG) dye from aqueous solution. Properties were evaluated by XRD, FTIR, SEM, EDX and BET analysis. Important and influential parameters on the adsorption process such as adsorbent amount, initial dye concentration, pH and contact time on the removal efficiency of contaminants from aqueous solutions were investigated. Maximum removal efficiency and adsorption capacity were 92.4% and 18.6 mg/g, respectively. In order to analyze the mechanism of experimental data, two First-order and Second-order kinetic models were used, which followed the second-order kinetics with R2=1. Also, the study of Freundlich and Langmuir isotherms showed that the isotherm model of Freundlich follows the R2=0.94, which indicates the non-uniformity of adsorption on the adsorbent surface.
