Pristine corn kernels as a pH-responsive biosorbent for selective removal of cationic and anionic dyes.

ABSTRACT: Wastewater treatment is of utmost importance in providing equitable and safe drinking water. The present study uses pristine corn kernel (CK) biosorbent to remove the anionic Acid Green 20 (AG20) and the cationic Crystal Violet (CV) dyes from different water samples. The CK biosorbent was thoroughly characterized with elemental analysis, Scanning electron microscopy (SEM), N₂ adsorption/desorption isotherm, Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FTIR), point of zero charge (pH_PZC), and Thermogravimetric analysis (TGA). The adsorption of dyes onto CK biosorbent was studied in batch and column modes. The experimental variables influencing the adsorption process were evaluated including the dose of CK biosorbent, contact time, pH, temperat
