| Abstract: | Determination of tin in ores by oscillopolarography in the system of H2SO4-VitC-NaCl.Its half wave potential appeared at-0.43V（vs SCE） Linear relationship beween the peak current and the concentration of Sn was obtained in the range of 0.25-7.5mg/L Relative standard deviation（RSD） was in the range of 0.5%-6.91%.The detection limit was 0.25 mg/L |
