The extract has maximum absorbance at 400-460 nm and the apparent molar absorptivity is 1.8 × 104l · mole−1 · cm−1 at 420 nm. The system obeys Beer's law at 420 nm in the range 0.16-3.20 mg/1 Ti, the detection limit being 0.1 mg/1. The method is found suitable for determination of titanium in aluminium alloys and silicate rocks.
