Khudyakova S. Methylthiopyronedimercaptides as the analytical forms for concentrating and determination of the Osmium.

The objects are the complexes of osmium (IV, VI) with 3-methyl-2,6-dimercapto-1,4-thiopyrone (H2M). Purpos: the obtaining of оsmium new analytical forms on the basis of its complexes for concentrating and quantitative determination. Меthods: spectrophotometric, potentiometric, ionometric, amperometric, IR-spectroscopy. Results: Proposed new analytical forms of osmium on the basis of its complexes with Н2М. Possibility the synthesis of electrode-active substances for membranes ion-selective electrodes on the basis of methyl thiopyrone dimercaptides osmium (VI) is shown. Spectrophotometric and electrochemical methods of osmium (IV, VI) determination in presence of the noble metals without separation is developed as well as hybride methods of оsmium determination which combine its concentrating by selective flotation osmium instrumental definition in real objects. Volume of providing: introduce on chemical faculties DNU. Region of utilization: analytical chemistry.
