ABSTRACT The proximate compositions of African elemi nut were investigated by analyzing the moisture content, crude fat, ash content, crude fibre, crude protein and total carbohydrates in the nut. The associations of official analytical chemist (AOAC, 2000) methods were used. The values obtained from the proximate analysis were; moisture content... Continue Reading
Sorption and desorption of rifampicin was assessed on three different soil. Sorption mechanism was studied in terms of equilibrium and kinetics at different pH. Linear, Freundlich and Langmuir isotherm models were adopted to study the isotherm. The experimental data were best described by pseudo-second order kinetics (R 2 = 1.00). It was observed...
