The report in this paper is about the synthesis of 2,3,7 trihydroxy -9- camphenal -6- fluorone (CAF) with a new reagent. The result of this study shows that Ti(IV)-CAF-Triton X-l00 can form a ternary complex(1:1:1),which has the maximum absorption at 562 nm and the molar absorption coefficient is 7.5×0-4 L.mol-1.cm-1. If the new spectrophotometric method is used to determine titanium contents in alloy steel samples, the result will be comparatively satisfactory. The method will be poved to be simple and direct.
