摘要: AbstractThis study aims to separate various forms of inorganic phosphorus as well determining the total in river sediments city Ibadan. Inorganic was fractionated using appropriate extractants obtain: loosely bound, Al-P, Fe-P, reductant and Ca-P. Results for ranged from 379 1156 μg P g-1. found be major constituent extractable all rivers surveyed. Ca-P dominant form 18 27 samples analysed. Al-P identified minor least significant non-apatitic sediment samples. The Bray-P1 available 11 100 results analysis are indicative high pollution some rivers. Speciation reveal that most is fixed apatitic form.
