【Abstract】 In this paper the authors have studied coexisting element interference and acidity effect in sample, corrected spectral overlapping interference and non-spectral interference by interference coefficient method and standard addition method respectively, and established a method for the determination of soluble heavy metal Pb, Cd and Cr in water based architectural coatings by ICP-AES. The method is accurate and of low detection limit, and can be applied to the inspection work of water based architectural coatings.更多还原
