Abstract
A new spectrophotometric method for the microgram determination of Ti from rock samples in the presence of commonly occurring metal ions has been developed. Ti is extracted from a 1-hexanol solution of benzohydroxamic acid (BHA) at pH < 2. The yellow extract has the maximum absorbance at 370 nm. The extraction was quantitative and obeys Beer's law at 370 nm over the range of 5-20 ppm Ti and the molar absorptivity is 2.4×103 l mol-1 cm-1.
