| Abstract：The meanwhile analysis of As and Sb in the geochemical exploration sample were reported by double-channel atomic fluorophotometer of AFS-1201 type.NH 4NO 3-(NH 4) 2SO 4-and ammonium salt were used to digest the sample and grow into AsH 3 and SbH 3 gas in HCl solution with two Perlent KBH 4. The gas which is led to quartz combustion tube burner is atomized. The hot atomic steam As and Sb sends out fluo rescence after absorbing definite wavelength of exciting line.The intensity of fluorescence and the... |
