Retention of molybdate by three Finnish mineral soils from 10-4 and 10-5 M sodium molybdate solutions at room temperature was investigated at pH 2.3-7.5. In the adsorption experiments 0.02 M KCl was used as ionic medium, and the samples were left to equilibrate for 72 h. The solid: solution ratio was 1:100 (w: v). Maximum adsorption occurred below pH 4.5, where about 60-80 % of added molybdenum was retained. Desorption of the adsorbed molybdenum was measured by adding 50 ml of 0.02 M KCl into weighed soil samples and shaking for 17 h in an apparatus with a mechanical stirrer. In each soil an appreciable amount of Mo was so tightly bound that it could not be removed by KCl treatment. |
