The extraction chromatography technique has been developed as the minor actinides (MA) recovering method from high radioactive liquid waste using porous silica covered with polymer and MA extractant. In the process, Mo and Zr occupy the adsorption site and disturb other FP elements to be adsorbed, therefore pretreatment procedure to remove these elements was evaluated.
