SELEKTIVITAS LIGAN DI-2-ETILHEKSIL FOSFAT (D2EHPA) UNTUK EKSTRAKSI LOGAM TANAH JARANG DENGAN SIMULASI DINAMIKA MOLEKULER
Abstract
Rare Earth Metals (REEs) are useful in a variety of high-tech applications. The need for LTJ is increasing over time. Separating and purifying REEs is difficult because REEs have similar properties to one another. So it is necessary to develop methods for separating and purifying REEs from their minerals. One of the separation methods uses the ligand Di-(2-ethylhexyl)phosphoric acid (D2EHPA) which has many advantages as an extractant in extraction. The aim of this research is to find out the ligand with the highest selectivity for REE separation using molecular dynamics and to find out which ligand can be better distributed into the organic phase. The methodology was carried out using BIOVIA Discovery Studio 2016 molecular modeling and energy optimization using the AMBER18 program. Computational studies can be performed to find starting points for synthesis in the laboratory. The REE complex with the D2EHPA ligand and three waters can be used in REE separation because it is more efficient and the stability of the complex is greater.
