Effect of adsorbent dosage, initial concentration and contact time on methylene blue dye removal using bamboo-derived activated carbon

This study delves into the efficiency of Methylene Blue (MB) dye removal using bamboo-derived activated carbon, exploring key factors such as adsorbent dosage, initial dye concentration, and contact time. The unique properties of bamboo-derived activated carbon play a central role as the primary adsorbent. Through systematic experimentation, optimal adsorbent dosages are 4g, considering saturation points for cost-effective removal. Lower initial dye concentrations which were 50 mg/L positively correlate with enhanced removal efficiency. The optimum time to absorb the Methylene Blue (MB) dye is 6 hours. After adsorption, functional group involvement was confirmed by shift in the N-H stretching peak from 3343.58 cm⁻¹ to 3336.22 cm⁻¹, suggesting binding alterations following interaction with MB dye. In summary, this research provides crucial guidance for the development of efficient and sustainable water purification strategies.
