Adsorption of hazardous Acid Violet 17 on Vachellia nilotica biochar: experimental and statistical physics modelling

Inadequate management of chemical industrial effluents necessitates the development of high-capacity, sustainable wastewater treatment technologies. This study investigates the adsorptive removal of hazardous Acid Violet 17 (AV17) dye using a novel biochar derived from Vachellia nilotica stems (VNBB). Characteriz...

Efficient Adsorptive Removal of Methyl Violet Dye from Wastewater Using Functionalized Groundnut Shell Biochar: Application, Mechanism, Modeling, and Optimization Study

This investigation focuses on the abatement of methyl violet (MV) dye from industrial effluents using the deployment of functionalized biochar prepared from methanol‐extracted groundnut shell residue. The biochar was functionalized by 30% tartaric acid(C4H4O6) to boost the surface functionality and adsorption performan...

Adsorption behavior of tetracycline and methylene blue onto microwave-assisted pine bark biochar

The widespread occurrence of antibiotics and synthetic dyes in aquatic environments poses serious environmental challenges due to their persistence and potential ecological impacts. This study evaluated the adsorption performance of tetracycline (TC) and methylene blue (MB) onto pine bark-derived biochar prepared via m...

Model-Based and Molecular-Level Evaluation of Methyl Orange Adsorption onto a Hazelnut Shell-Based Carbonaceous Adsorbent

This study presents a combined model-based and molecular-level assessment of methyl orange uptake by a hazelnut shell-based carbonaceous adsorbent. Batch experiments were conducted under previously optimized conditions, namely a dye concentration of 42.65 mg/L, adsorbent loading of 1.29 g/L, temperature of 30.4 °C, and...
