This investigation was undertaken to develop a rapid and accurate differential spectrophotometric method for the determination of titanium in titanium metals. The reaction between titanium and salicylic acid in pH 5±0.5 solution to produce the yellow-colored complex was chosen for this application. The reference standard solution contained 1.20 mg of titanium per 100 mL of pH 5±0.5 solution. Beer’s law was conformed to within the range of 1.20 to 1.50 mg of titanium per 100 mL of pH 5±0.5 solution. At pH 5±0.5 molybdenum, niobium, thorium tungsten, manganese, aluminum, lead, cobalt, nickel, chromium, vanadium, calcium, and magnesium do not interfere. Iron and copper may be masked by the addition of EDTA.
