Abstract

Cassava peel has become conspicuous environmental waste which affects the natural integrity of the environment. Several researchers have extracted wax from agro-wastes such as sugarcane bagasse, banana peel, apple pomace etc. The present study extracted wax from cassava peel using soxhlet extraction method with a mixture of benzene and methanol as the extracting solvents. The percentage yield of crude wax from cassava peel was 8.51%. The wax extracted was characterised using fourier transformed infrared spectroscopy (FT-IR), ultraviolet-visible spectroscopy (UV-Vis) and scanning electron microscopy (SEM). The physicochemical properties were studied; acid value, saponification value, ester value, melting point and iodine value. The FT-IR prominent peaks were obtained at 3224(–OH), 2928 (–CH2), 1376.96 (–CH3), 1708 (–CHO), 1035 and 885, indicating presence of alcohols, alkanes, aldehydes, and lignin compounds, respectively. The UV-Vis analysis showed fatty acids, conjugated dienes, and hydroperoxides at 232 nm and conjugated trienes at about 255 nm. The results of the physicochemical properties were evaluated; acid value, saponification value, ester value, melting point and iodine value as 23.4 mg/KOH/g, 103.42 mg/KOH/g, 80.02 mg/KOH/g, 63.5°C and 90.3 g/100g, respectively. This study revealed that wax obtained from cassava peel is a potent product for diverse industrial applications.
