The basis of the method is the formation of stable complex of `soft base' FBIMMT with `soft acid' ruthenium(M). The reagent FBIMMT in n-butanol easily forms extractable yellow coloured complex with ruthenium(III) in acetate buffer of pH 4.8. The absorbance of [Ru(III)-FBIMMT] complex is measured at 394 nm against the reagent blank. Good linearity range of concentration up to 27.0 mu g mL(-1) of ruthenium(III) is attained with correlation coefficient R-2 = 0.998. The optimum concentration range is 6 to 27.0 mu g mL(-1) which is deduced by Ringbom's plot. The apparent molar absorptivity found to be 2.75 x 10(3) L mol(-1) cm(-1). Some additional characteristics such as limit of detection (LOD = 0.48 mu g mL(-1)), limit of quantification (LOQ = 1.19 mu g mL(-1)), and Sandell's sensitivity (SS = of 0.0367 mu g cm(-2)) arc also estimated. The composition of [Ru (III)-FBIMMT1 complex has been established from Job's continuous variation method, mole ratio method, and log-log plot method. The specificity towards ruthenium(III) is well studied and appropriate masking agents are applied wherever required to boost it. The intra-day and inter-day precision values are found to be brilliant with % relative standard deviation of 0.52 and 0.68 respectively with % accuracy within the range of 99.00-100. The method is effectively used for determination of ruthenium(III) from water samples, binary and ternary synthetic mixtures, fissium alloy samples and catalyst materials. A scheme for sequential group separation of ruthenium(III), palladium(II) and osmium (VIII) has also been developed. The reproducible results of the present method confirm that the method has a good potential for quantitative determination of ruthenium(III) from various matrices. (C) 2020 Elsevier B.V.
