| Abstract: | To adopt the method of flowing injection of atoms to absorb spectrum to determine the trace selenium in the rich selenium vegetables, the test should be conducted on the condition of a lamp electric current of 10mA, seam of 0.5nm, wave length of 196.0nm, electric heating atomic machine's heating electric pressure of 80V and gas flow (argon) of 240 mL/min. A good linear relation can be obtained within a density range of 0～350.00 μg/L, and the tropic equation is A=0.00293C (Se) + 0.0216 and the relative coefficient r=0.9988. Easy to handle, the method carries high automation degree, fine sensitivity and strong practicality. |
