| Abstract: | A method is established for determination of natrium in IP-300B by atom absorption spectrophotometry(AAS). The samples were determined after digestion with H2SO4 and cineration. A linear relationship between the concentration (range of Na+ 0.10～2.00μg/mL)and absorbency, the sensitivity(3.5×10-3μg/mL/1%),the precision(S:0.0068;CV%:3.0) and recovery of standard addition(92.3%～106.2%)were good enough for determination of trace natrium in IP-300B. |
