ABSTRACT

The paper presents an optical study of the binary system Rh(III)-1,2,3-cyclohexanetrionedioxime. The formation conditions and the analytical application of the formed complex for spectrophotometric determination of  Rh(III) were studied. The composition of the Rh(III) complex with this particular ?-dioxime was determined by the continuous variation method. Its instability constant is Kinst = 3.70?10-10mol2L-2.
