Abstract This research focuses on the effective removal of methylene blue dye using silica gel synthesized from chemical
glass bottle waste as an environmentally friendly and cost-effective adsorbent. The adsorption process was optimized using Box-Behnken Design (BBD) and Response Surface Methodology (RSM) to investigate the influence
of pH (6; 8 and 10), contact time (15; 30 and 45 min), adsorbent mass (30; 50 and 70 mg), and initial concentration (20; 50 and 80 mg/L) of the adsorbate on the adsorption efficiency. The BBD was conducted using Google
Colaboratory software, which encompassed 27 experiments with randomly assigned combinations. The silica gel
synthesized… More >
