Abstract

This study aimed to investigate Egyptian date pits' potential to remove a cationic dye, specifically methylene blue (MB), from aqueous solutions. Characteristics of methylene blue and interaction between methylene blue and Egyptian date pits were characterized using the Fourier transform infrared spectrometer, scanning electron microscope, and Brunauer– Emmett–Teller analysis. The effect of several parameters including, adsorbent dose, and contact time, temperature and pH solution were assessed. The adsorption was increased by decreasing dye concentration, temperature, increasing contact time and dosage up to equilibrium values which was 25 °C, 20 min, and 0.1 g adsorbent, respectively. At high pH, the adsorption was promising. The results demonstrated that the Egyptian date pits are an effective and good adsorbent for removing Methylene blue in wastewater.
