Document Type and Number:
Japanese Patent JPH0472581
Kind Code:
B2
Abstract:
PURPOSE:To recover efficiently the residual liquid without diluting it by extrud ing the liquid to be adsorbed or the liquid to be eluted which remains in a column by means of air after an adsorption process or an elution process of components contained in the liquid for the column. CONSTITUTION:In case of chelate resin adsorbed selectively with Bi and Sb dissolved into, for example, a copper electrolyte, after this resin is washed with water and eluted by using 6N-HCl, air is blown into so as to attain about <=19.7cm<3>/cross-sectional area of column (m<2>)/min. The extrusion can be performed by controlling it to the extrusion velocity such as this method without a affecting throughly the adsorption capacity of resin for Bi plus Sb and the elution characteristics due to 6N-HCl. In addition to this, the extraction velocity of liquid from the column is quick and uniform and also the discharged quantity of liquid is made much.
