One of the main Egyptian monazite ore project targets is to find a new economical and local liquid and solid materials for uranium and thorium separation, extraction and/ or purification.For this reason, we thought of using chelation with heterocyclic ring systems and ion exchange resins, therefore, we decided to synthesize some novel heterocyclic system containing chelating groups like NH2, SH, OH or C=O in addition to the synthesis of glycine modified cross-linked chitosan resin from laboratory available, cheap and easily obtainable starting materials.
