Abstract：
Abstract: The experimental conditions for the simultaneous determination of molybdenum and tin by standard additiondual wavelength spectrophotometry with trimethoxyphenylfluorone were studied. Meanwhile, the synthetic sample of molybdenum and tin and aluminum alloy samples were determined. In the presence of sulfuric acid medium and surfactant OP10, the determination wavelength and reference wavelength for spectrophotometric determination of molybdenum and tin with trimethoxyphenylfluorone are 524 nm and 503 nm, respectively. The ranges obeying Beer's law were 020 μg/25 mL and 015 μg/25 mL, respectively. This method was applied to the simultaneous determination of molybdenum and tin in synthetic sample of molybdenum and tin and aluminum alloy actual samples. The recoveries were 97 %106 %, and the relative standard deviations (RSD) were less than 3 %.
