摘　　要：建立紫外分光光度法定量测定一氯三（三苯基膦）合铑（Ⅰ）的方法。测定波长为350 nm,溶剂为三氯甲烷,线性范围为0.03~0.17 mg/mL,γ=0.9990,平均回收率为99.1%,RSD=2.0%（n=6）。该方法具有简单、灵敏、准确的特点,适合于一氯三（三苯基膦）合铑（I）的快速测定。A spectrophotometric method has been established for the determination of chlorotris-（triphenyphosphine）rhodium（Ⅰ）.The detection wavelength was 350 nm and chloroform was chosen as solvent.The linear range of chlorotris（triphenyphosphine）rhodium（Ⅰ） was found to be 0.03～0.17 mg/mL（γ= 0.9990）,and the average recovery was 99.13% with RSD being 2.0%.The method is simple,sensitive,and accurate and suitable for quick determination of chlorotris（triphenyphosphine）rhodium（Ⅰ）.
