Clean water resources are becoming increasingly limited and advances in toxic ion removal technology are essential. Sorption using adsorbent materials have been used to remove toxic ions from water. However, the ion selectivity and absorption capacity of these materials still need to be improved to clean up water more effectively and sustainably. In this study, we synthesized a metal organic frameworks consisting of terbium and oxalate (TOF) and the ion absorptivity of the TOF was investigated by sorption tests. The crystal structure of the TOF before and after ion adsorption provided useful insights into the ion selectivity of the adsorbent.
