    Efficient removal of crystal violet dye from aqueous solutions using sodium hydroxide-modified avocado shells: kinetics and isotherms modeling by Mohamed Ait Haki, Abdelaziz Imgharn, Nouh Aarab, Abdelghani Hsini, Abdelillah Essekri, Mohamed Laabd, Habiba El Jazouli, Maria Elamine, Rajae Lakhmiri, Abdallah Albourine

    Published 2022-01-01
    “…The main objective of this study is to optimize a new composite for the depollution of contaminated water. The sodium hydroxide-modified avocado shells (NaOH-AS) were firstly prepared, characterized by field-emission-scanning-electron-microscopy (FE-SEM), X-ray energy dispersive spectroscopy (EDS) and Fourier transforms infrared (FT-IR) spectroscopy, and applied for efficient removal of crystal violet dye (CV) in wastewater. …”
