文摘The extraction behavior of thallium (Tl￣+ , Tl￣(3+) ) with D_2EHMTPA di-(2-ethythexyl) monothiophcos-phoric acid from sulfuric acid has been studied and compared with D_2EHPA. The solid complex of Tl[(RO)_2PSO] has been synthesised. Its composition was determined by scanning electron microscopy, energydispersion X-ray spectrometry and slope method. The IR and NMR spectra studies showed that thallium coordi-nates with P=S bond. The heating stability of the complex has been studied by TG-DTA analysis.
