Abstract

The present invention provides an easy-to-handle biopolymer composite ion-exchanger with high cesium selectivity, and method for manufacturing this ion-exchanger with ease and good reproducibility, and relates to a cesium separation/recovery agent comprising a composite ion-exchanger with high cesium selectivity by employing a calcium alginate gel as a matrix and loading this matrix with an inorganic ion-exchanger; and to a manufacturing method therefor.
