Abstract The manufacture and industrial use of dyes generate highly colored, often non-biodegradable effluents that pose serious environmental and public health risks.The aim of this study was to evaluate the capacity of ferula stems from the Saida region to serve as a biosorbent in the treatment of water synthetically contaminated with two dyes, Congo Red (CR) and Methylene Blue (MB). The results of XRD, FTIR, SEM, and EDS analyses confirm that ferula stems biomass has an amorphous lignocellulosic structure with functional groups and surface characteristics that favor dye adsorption. MB shows a higher adsorption capacity than CR, with a maximum retention of 33.83 mg/g versus 21.0 mg/g for CR. In competitive adsorption, the biomass showed a greater affinity for MB with 85% at higher concentrations. Adsorption data were well described by the Langmuir isotherm (R2 ≈ 0.95). These results demonstrate the promising applicability of Ferula biomass for treating dye-contaminated waters.
Industrial dye pollution poses a serious threat to aquatic ecosystems and public health, necessitating the development of efficient and sustainable remediation strategies. In this study, a biomass‐based adsorbent was prepared from

Methylene blue (mb) is a synthetic dye used in many industries due to its unique color and characteristics. Due to its usage on a large scale substantial amounts of this dye are constantly released into different environmental compartments, which have posed severe threats to the environment. As effective adsorbent...

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...

This study explores the adsorption performance of clean peanut husk (CPH) as a sustainable and low-cost biosorbent for removing methylene blue (MB) from aqueous solutions. Batch experiments investigated the effects of dye concentration, biosorbent dosage, pH, particle size, and temperature. FT-IR analysis confirmed the...
