Calcium-Rich Biochar Derived from Cactus Feedstock and Its Efficient Adsorption Properties for Industrial Dye

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(2), P. 894 - 894

Published: Jan. 17, 2025

The leather industries are large producers of industrial wastewater. present work investigated the performance calcium-rich biochar derived from cactus cladodes (CCB) as an adsorbent in treatment this Biochar samples (CCB500, CCB600, and CCB700) were produced by slow pyrolysis at 500, 600, 700 °C tested adsorbents Repanil Blue (RB) dye. tests carried out under various experimental conditions. RB dye removal increased with contact time, dose, concentration. With concentrations between 10 125 mg/L, efficiencies 80, 80 100% reached using CCB500, CCB700, respectively. Langmuir model pseudo-second-order described chemisorption a high correlation factor (R2). highest adsorption capacity 56 mg/g was obtained CCB700 within 5 min. results strongly suggest that biochars promising for aqueous solutions.

This work aims to synthesize and characterize an easily recoverable magnetic composite (orange peel [OPC]) from orange (OP) apply it as effective adsorbent for the removal of industrial drug (diclofenac (DFC)) aqueous solutions in batch mode. The OP OPC characterization through various techniques including Fourier transform infrared, scanning electron microscopy coupled with energy-dispersive spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller, thermogravimetric analysis shows that has interesting physicochemical properties comparison numerous other adsorbents. DFC by is found be time-dependent, equilibrium state obtained after 90 min. Moreover, at a temperature 30 °C, adsorption capacity this material estimated 37.0 mg·g–1, which higher than In addition, thermodynamic study results indicate feasible, exothermic, spontaneous process. All these prove magnetized wastes can considered promising efficient under wide range experimental conditions.

Effectiveness of plant-based biosorbents in textile dye removal from aqueous solutions: isotherm, kinetic, and thermodynamic studies

Comptes Rendus Chimie, Journal Year: 2025, Volume and Issue: 28(G1), P. 339 - 348

Published: March 31, 2025

The pollution of water resources by hazardous contaminants is a major obstacle to the provision safe and potable worldwide. Cost-effective, innovative, renewable, environmentally friendly technologies are essential for wastewater treatment. In current work, potential using raw date palm petiole (DPP) removal Bezaktiv Marine S-BL (SBL) dye investigated under wide range experimental conditions in batch mode. Experimental results show that SBL DPP highly dependent on contact time, initial pH, concentration, temperature. relatively rapid where equilibrium state reached within time 120 min. Moreover, biosorbent exhibits high stability adsorption ability over pH (4–12). Furthermore, increases with increase concentration. maximum capacity evaluated be 110 mg/g, which much higher than numerous other materials. addition, thermodynamic study indicates feasible exothermic spontaneous process. findings present indicate untreated wastes can considered effective materials treatment textile dyes general particular.
