| Abstract: | To test the lead in feed enzymes, the samples were treated by the wet digestion, detected by the graphite furnace atomization, matrix modifier and standard addition method were also used to get the satisfied re- sults. The recoveries were in the range of 98.45%-107.9% for standard rice, and 90.5% -114.0% for samples, the RSD was less than 5.0%. |
