Research into the synthesis and use of a novel copyright compound, thiazoethyl methyl eugenoxyacetic acid (TMEAA) for selective transport of Cu(II), Cd(II) and Cr(III) metal ions in the bulk liquid membrane (BLM) technique was Choline/Inositol conducted.TMEAA was synthesized from eugenol.Eugenol was acidified into eugenoxyacetic acid and subsequently esterified using 4-methyl-5-thiazoethanol.
Analysis of the result was performed using GC-MS and FTIR.The TMEAA obtained was liquid, viscous, blackish-brown and fragrant, with a yield of 88%.This compound was soluble in benzene and chloroform but insoluble in methanol.
The GC-MS analysis result showed the presence of a single peak, with a retention time of 26.5 min and an area of 100%, while the disappearance of vibration mode at 1727 cm-1 was attributed to acid absorption and the FTIR spectrum indicated that formation of an ester group had occurred.TMEAA was used as a copyright compound in the BLM technique to transport Cu(II), Cd(II) and Cr(III), Sun Cap using chloroform as a solvent.
The results showed that TMEAA was more selective for Cu(II) and Cd(II) than Cr(III).Moreover, the research proved that N and S groups of TMEAA were selective for Cu (II) and Cd (II).
