Characterizations of banana peel and its efficiency for copper adsorption

บทคัดย่อ ( Abstract )

This research described the chemical and physical characterizations of banana ( Musa sapientum Linn) peel for adsorption of copper. The FT-IR spectroscopy, BET (surface area) and SEM (scanning electron microscopy) coupled with EDX (energy dispersive X-ray) analysis were used for characterizations, while copper concentration was determined by ICP spectroscopy. The different parameters: pH values 3.0 to 9.0, banana dose (0.1 g to 0.7 g) and adsorption times (30 min to 180 min) were investigated for studying an adsorption efficient. It was found that banana peel (0.1 g) was a bio-adsorbent for copper adsorption under the suitable conditions at pH 7.0 and 90 min adsorption time. The sorption pattern was additionally found to be in linear form, according to the Freundlich and Langmuir equations with R 2 = 0.966 and 0.994, respectively
