| Abstract: | A new method for the determination the trace amounts of lead in Aloe by GFAAS with on line solvent extraction flow injection was proposed, APDC/MIBK were used as extraction solvent in this method. Extraction condition, manifold parameters and interference of the coexist component were investigated .The precision (RSD) is 3.74%, the detectable limit (3σ) is 3.2×10 12 g, the recovery of standard addition is 93～99% .Samples of aloe were detected , and the result is satisfactory. |
