The absorption maximum and molar absorptivity of the red coloured species are 500 nm and 6.4 x 105 litre mole-1 cm-1 for FPH, and 510 nm and 6.3 x 103 litre mole-1 cm-1 for TPH. Beer's law is valid over the concentration range 0.2-11.52 ppm of ruthenium(III) for FPH, and 0.5-9 ppm of ruthenium(III) for TPH. The proposed methods offer the advantages of simplicity, sensitivity, stability and rapidity without the need for extraction.
