ABSTRACT The article published the results of the analysis of lead content in paint by flame atomic absorption spectrophotometry (F-AAS). Results showed that the method has good repeatability (RSD = 4.74%), low detection limit and quantitative limits (LOD = 0.2157mg/l, LOQ = 0.718mg/l), linear range from 0 -20 mg/l with linear calibration curve is y = 0.0211x + 0.0145 (R2 = 0.9961), the recovery is 98.672%. The method has been applied to the analysis of lead content in some paint samples on the market for good results. Keywords: Lead, paint, F-AAS. |
