Abstract

The elemental compositions present in the shells of palm kernel and coconut were determined using atomic absorption spectrophotometer (AAS) and flame photometer after digestion. The concentration of the elements in coconut shell were; calcium (24.00±0.26 mg/kg), iron (27.41±0.21 mg/kg), zinc (17.05±0.26 mg/kg) and magnesium (125.20±0.21 mg/kg) were higher when compared to their compositions in palm kernel shell with calcium (15.00±0.03 mg/kg), iron (14.57±0.03 mg/kg), zinc (10.00±0.26 mg/kg) and magnesium (98.20±0.03 mg/kg). Other element concentrations were; potassium (220.20±0.03 mg/kg), sodium (10.40±0.01 mg/kg) and copper (4.64±0.03 mg/kg) in palm kernel shell were higher as compared to coconut shell with potassium (198.05±0.17 mg/kg), sodium (15.40±0.32 mg/kg) and copper (3.00±0.21 mg/kg). However, lead was below detectable limit. Palm kernel and coconuts shell have similar metals present although in different concentrations. This study revealed that the shells of palm kernel and coconut contains substantial amount of mineral elements which make them suitable alternative cheap sources for these minerals element.
