ABSTRACT:
In a process for the separation of elements by chromatography in which a front zone and a rear zone are present in front of and in rear of an adsorption band of elements, a high column efficiency can be attained by developing the adsorption band of elements without causing the entry of a main eluent having a relatively high concentration into the front zone. According to the present invention, elements can be separated into individual species not only in a high state of purity but also in a high state of concentration, so that the productivity of elements may be extremely increased as compared with that of conventional methods. In addition, according to the present invention, the amount of eluent employed is remarkably small as compared with that in conventional methods. Therefore, the present invention is very advantageous for the separation of elements from an industrial standpoint.
