Thermal Upcycling of Spent Molasses Concentrate for Malachite Green Removal: Multilayer Adsorption Mechanism and Economic Potential

Waste basalt quarry dust for efficient adsorptive removal of malachite green dye: experimental and modeling studies

This study investigates the adsorption performance of waste basalt quarry dust (BQD) for the removal of malachite green (MG) from aqueous solutions. The physicochemical properties of BQD were characterized using FTIR, SEM, EDS, zeta potential, BET, TGA, and XRD analyses. Single-parameter batch adsorption experiments we...

Adsorption Kinetics and Performance of Methylene Blue onto Alkali-Treated Sugarcane Bagasse Biochar

Sugarcane bagasse (SCB), an abundant agricultural byproduct, was utilized to synthesize an effective biochar adsorbent via NaOH pretreatment and muffle furnace pyrolysis at 500 °C for the removal of methylene blue (MB) dye from aqueous solutions. Surface characterization using Fourier-Transform Infrared (FTIR) spectros...

Sustainable Valorization of Sewage Sludge Into NaOH‐Activated Biochar for Malachite Green Removal From Wastewater

This work investigates a circular economy strategy by converting sewage sludge into efficient adsorbents for malachite green (MG) removal. The adsorption performance of raw sludge (RS) was compared with NaOH‐activated biochar (NAB) prepared by pyrolysis and chemical activation. Physicochemical characterization (XRF...

Soursop Biomass-Based Activated Carbon as a Textile Dye Adsorbent

Textile industries discharge vast amounts of polluted wastewater, with dyes being major contributors to severe environmental issues. Activated carbon (SBAC) was synthesized from residual soursop biomass via ZnCl2 chemical activation at 450 °C for 1 h to remove Remazol Black B dye from aqueous media. Activation increase...

Removal of Malachite Green via X-Faujasite Adsorption: A Multi-Model Investigation of Adsorption Kinetics and Thermodynamics

Industrial effluents containing synthetic dyes, such as Malachite Green Oxalate (MG) from tanneries, pose a major ecological challenge. In this work, we investigate the potential of a newly developed X-Faujasite (X-FAU) as an effective sorbent for MG, prepared through hydrothermal synthesis. The obtained material was t...
