文摘
- •
A new method for determination of selenium species in radix puerariae is described.
- •
Sample was pre-concentrated using 5-sulfosalicylic acid –SMNPs.
- •
The detection limits of this method were improved by 10 times.
- •
The selenium species was extracted using ultrasonic extraction system.
- •
The Se sensitivity is the highest when CH4 was used for reaction gas.
