Abstract

Cassava peel has become conspicuous environmental waste which affects the natural integrity of the environment. Several works have extracted wax from agro-wastes such as sugarcane bagasse, banana peel, apple pomace etc. In this study wax was extracted from cassava peel using soxhlet extraction method with a mixture of benzene and methanol as the extracting solvents. The percentage yield of crude wax was 8.51 % on wet basis. The wax extracted was characterised using Fourier transformed infrared spectroscopy (FT-IR) and ultraviolet-visible spectroscopy (UV-Vis). The physicochemical properties were also 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 the 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 values, respectively. This study revealed that wax obtained from cassava peel is a potent product for diverse industrial applications.
