Formation of Thallium Sulphide Layers on Polyethylene (PE) Sulphurised in a Solution of Higher Polythionic Acid

摘要

Thallium sulphide layers of different composition were obtained on the surface of polyethylene when it was sulphurised in a solution of higher polythionic acid, H2S33O O Is and S 2p showed the bond of thallium with sulphur in T1S and TI2S , but TI2SO4, Tl(0H)3, Ss and TI2O3 were also found on the surface of the layers. Five thallium sulphide phases T1S, Tl2S, TI2S2, TI4S3 and TI2S5 have also been identified in the layers by X-ray diffraction. The peaks of the T1S phase predominate in the diffractograms.
