| 内容記述 | In order to confirm directly the adsorptive behavior of the trace elements in the isolated undisturbed mountain pond "Yasha-ga-Ike" onto the sedimentary grains of chert by experimental techniques, both the surface rubbing-off and the nitric acid leach for the grain samples were carried out. In the former case, the grain sample was rubbed gently in an agate mortar by paste and the sieved fractions were analyzed by neutron activation in order to compare the element concentrations on and near the grain surface and the inner porton. In the latter case, the grain sample was leached with 8N nitirc acid near the boiling point, and the leached amount was obtained either by ICPMS analysis of the leached solution or by taking the difference of the element concentrations of the particle, obtained by the neutron activation, before and after the leach. The experimental results showed that (1) the concentration of element on and near the particle surface are clearly higher than that of the particle matrix and (2) the concentration of leached element is fairly close to that of adsorbed element over a wide range of particle diameter. These results are considered to give confirmative evidences of element adsorption on the surface of the particles. The concentration of adsorbed element can be obtained by subtracting the concentration of grain matrix, which is obtained by extrapolating the particle size to an infinitive, from the whole concentration of constituent element in the particle. | |||||
