通过样品中共存元素干扰和酸度效应的研究 ,采用干扰系数法和标准加入法分别校正了光谱重叠干扰和非光谱干扰 ,建立了ICP AES测定水性墙面涂料中可溶性重金属铅、镉和铬的方法。该方法准确 ,检出限低 。

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.
