Activated carbon from melamine-impregnated paper

Activated carbon was prepared from waste melamine-impregnated paper (MIP) by pyrolysis with activation NaOH. The adsorption parameters such as carbonization temperature (300, 350, 400, 450 °C), NaOH to C ratio (2:1, 3:1, 4:1, 5:1), and initial methylene blue (MB) dye concentration (20 600 mg/L) were studied. results fit the Langmuir isotherm model pseudo-second order kinetics. It found that activated MIP had a maximum capacity of 497 mg/g at 400 °C (carbonization temperature) (2:1). highest removal via 99.4%. π-π interaction between molecules active proposed be primary driving force for adsorption. This adsorbent based on shown highly promising water decontamination applications.
