[Determination of bismuth in little sample by FAAS with home-made hydride generator].
In order to determine Bi in little sample a simple hydride generator was designed, which was made easily and operated conveniently. The generator consumed sample of 0.5-1.0mL with the content of Bi of 10-100ng/mL, the precision, senstivity and detection limit were shown to be satisfactory. With this apparatus the Bi in little sample was determined by FAAS and the regression equation c = -30.17 + 190.6A, relation coefficient r = 0.9934, residual standard deviation of A for fixed c,SA.C = 2.737, standard error of regression SB = 4.001 and t-test result, where alpha = 0.001, showed that the equation was significant in statistics. The detection limit in this method was 3.69ng/mL.
