Abstract:
OBJECTIVE:To establish atomic absorption spectrometry for the assaying of the microelement manganese in Changtong oral liquid.METHODS:The light source was hollow-cathode lamp with wavelength at 279.5nm,the electric current of the light was 3.0mA,the slit-width was 1.2nm,the air flow rate was 5.0L/min and the flow rate of acetylene was 1.0L/min.RESULTS:The calibration curves was in linear correlation with adsorption when the detection concentration range of manganese was 0.5～2.5?g/ml(r=0.9 997),the average recovery was 99.24%(RSD=2.06%,n=5).CONCLUSION:This method is simple,fast,accurate,sensitive and precise.
