Novel adsorbent based on Argan Spinosa leaves modified with citric acid for effective removal of crystal violet dye from textile effluents

     This paper of the day develops an adsorbent based on Argan Spinosa leaves modified with citric acid for effective removal of crystal violet dye from textile effluents. The study tested the efficiency of the adsorbent to be 99.5% and the adsorption capacity of 335.06 mg/g for crystal violet at pH 7. They have optimized operational parameters such as contact time, initial concentration, pH, biosorbent dosage, and solution temperature. Additionally, the paper explained in detail the kinetics isotherms, and thermodynamics, governing the adsorption process.
