The differential pulse anodic stripping voltammetry (DPASV) method described is based on the one reported by Hasse et al., but adapted to normal laboratory conditions. The values obtained in the estimation of the analytical parameters (linearity, detection and quantification limits, precision and accuracy) show that in the conditions described the method is sensitive enough, reliable and useful for determining these elements in infant formulas. A comparison between DPASV and atomic absorption spectroscopy (AAS) methods in the conditions described here shows that the former is less sensitive but that they are similar in precision. The cadmium, copper, lead and zinc contents of different types of infant formulas marketed in Spain are reported.
所描述的差分脉冲阳极溶出伏安法（DPASV）基于哈瑟等人报道的方法，但适用于常规实验室条件。在分析参数（线性、检测限和定量限、精密度和准确度）评估中获得的值表明，在所描述的条件下，该方法对于测定婴儿配方奶粉中的这些元素足够灵敏、可靠且有用。在此处描述的条件下，DPASV与原子吸收光谱法（AAS）的比较表明，前者灵敏度较低，但精密度相似。报告了西班牙市场上不同类型婴儿配方奶粉的镉、铜、铅和锌含量。
