| Research Abstract |
It is found from the results of copper ion adsorption experiment that the copper ion adsorption properties vary remarkably with the degree of weathering of samples. The ignition loss which has been adopted as a criterion of the degree of weathering is related to the amount of adsorbed copper ion. The slightly weathered sample shows Langmuir type and the severely weathered one is given by BET type from the sdsorption characteristics examining in detail, and the adsoption phynomenon for the severely weathered sample is confirmed as the adsorption within the pore systems caused by increasing degree of weathering by means of X ray micro analyer. Especially, the copper ion adsorption and the change of concentration for undisturbed sample of the weathered sample are charaterized by the soil fabric which is dependent on the pore size distribution.
