[0003] Tin chloride or oxychloride is one of the impurities in titanium tetrachloride. Usually, after production, the tin content of titanium tetrachloride will be tested to determine whether titanium tetrachloride meets the standard, thereby ensuring the quality of titanium sponge. The method of tin in titanium chloride mostly is traditional chemical analysis method, such as, complexometric titration, its step is simple, easy to operate, but accuracy is lower, easily pollutes environment; Spectrophotometry, its detection accuracy is high, but The process is complicated, cumbersome, time-consuming and labor-intensive, and it is easy to cause sample contamination, and then pollute the environment; nuclear magnetic resonance method has high accuracy and is easy to operate, but requires high equipment requirements, high energy consumption, and high detection costs. In addition, Currently commonly used detection methods, the interference of titanium, aluminum, vanadium, iron, and silicon metal elements has a greater impact on the detection results, especially the interference of titanium elements is the largest
