Abstract In this work, abundant natural and industrial materials were used in concert to create a new nanocomposite made of Nanocellulose (NCW) hydrolyzed by nitric acid cobalt tungstate (CoWO4) prepared precipitation methods from sodium chloride. The result was cost-effective as an adsorbent photo-degradation with exceptional organic pollutants (OP) refinery wastewater (RWW). This composite exhibited outstanding mechanical stability eliminated oxidation adsorbent. All comprehensively characterized through XRD, FTIR, DRS, TGA, BET, EDX, FE-SEM analyses. A comparison between the nanocomposite's UV solar light performance, considering factors like temperature, pH, time, dose, so on. best conditions identified: pH levels 8–9, time 120 minutes, temperature 70°C, dose 1.0 gm. Upon applying these optimized RWW samples, high removal ratios achieved: 97.4, 90.3, 64.2, 49% for CoWO4/NCW, NCW, NaOH/CW, CW respectively. These findings underscore composite's potential economical efficient biosorbent OP elimination, alongside its effectiveness solar-assisted degradation processes.

This study presents two modified polymers for Cu2+ ion removal from aqueous media. Shredded maize stalk (MC) and a strong-base anionic resin (SAX) were with indigo carmine (IC) in order to obtain different complexing polymers, i.e., IC-MC SAX-IC. Initially, the complex reaction between IC solution was studied. Additionally, formation Cu2+-IC liquid solutions evaluated at pH ranges of 1.5, 4.0, 6.0, 8.0, 10.0, respectively. For ions, adsorption onto IC-SAX batch experiments conducted. The contact time evaluating optimum ions on materials established 1 h. Efficient SAX-IC = 10 achieved. depends quantity retained MC SAX. At 2.63 mg IC/g MC(S4) 22 SAX(SR2), high amount reported. highest capacity (Qe) obtained 0.73 mg/g, IC-SAX, it attained 10.8 mg/g. Reusability performed using HCl (0.5 M) solution. High regeneration reusability studies confirmed, suggesting that they can be used many times remove matrices. Therefore, development could suitable wastewater.

For sustainable development, wastewater treatment and recycling are inevitable; using adsorbents to treat is widely accepted. This article aimed synthesize (novel biochars) from agricultural wastes investigate the adsorption behaviours of Pb(II) Cd(II) on novel biochars. Nitrogen purged biochar (NPBC) was synthesized by pyrolysis with nitrogen purgation wheat straw; whereas, steam activated (SABC) pyrolysis-cum-hydrothermal (steam) activation. Synthesized NPBC SABC were characterized physical, chemical, XRD, FTIR, SEM–EDX methods. more porous amorphous in nature higher specific surface area (SSA), but consisted relatively less polar functional groups than that NPBC. The external layer both negatively charged (pH > pHPZC). Results revealed exhibited 97% 80% recovery efficiency Cd(II), respectively, while demonstrated removal efficiencies 87.6% 69.4%, at initial concentrations 50 5 mg L−1. Adsorption upon occurred spontaneously, also exothermically, decreased increased reaction temperature. maximum capacities (qmax) for 452.13 1117 g−1, whereas those 314.9 470.43 according Langmuir isotherm approach (R2 0.989). So, performed better removing metals wastewater. Both exhibit substantial prospects regeneration consequent adsorbent recovery. Hence, designed can be very effective towards cationic toxic heavy metal
