| Abstract: | A new fluorimetric method for determination of trace lead in fresh apple was established. The linear range for the determination of lead is 0.03～2.00 mg/mL, the detection limit is 9.1×10~-3mg/mL, the method is applied to determine trace lead in apple, and the recovery is 96.22%～100.04%. |
