  • The optimization of the reductant and acid concentration for stannane($SnH_4$) generation was investigated by using a continuous flow hydride generator combined with an inductively coupled plasma-atomic emission spectrometer. Several different prereductants were studied to remove the interfering effect of fluoride ion on the hydride generating of tin. The optimum acid concentration was 0.5-1.0 M for the 1-2% $NaBH_4$ and 1.0 M NaOH and the interfering effect of fluoride ion was minimized using boric acid and L-cysteine mixed solution as a prereductant. The reconveries of tin at 20 ng/mL level in the solution containing fluoride ion were 100~108 %.
