差动脉冲阳极溶出伏安测量法可用来 测定十二种不同动物食物中的微量重金属镉、铅、铜和锌。有些重金属,象镉、铅、铜和锌,由于其毒性(镉和铅)及它们在生命体中的重要作用(铜和锌),它们在动物饲料中的含量是值得重视的。阳极溶出伏安法测定低含量重金属非常灵敏。 于工业过程出口处收集食品工业付产品如葡萄渣等,使其凝结并切成大约2mm碎块。在80℃下干燥,磨碎可通过1mm筛网,作为试样。
Differential pulse anodic stripping voltammetry can be used to determine the trace amounts of cadmium, lead, copper and zinc in twelve different animal foods. Some heavy metals, such as cadmium, lead, copper and zinc, are valued for their animal feed because of their toxicity (cadmium and lead) and their important role in life (copper and zinc). Anodic stripping voltammetry is very sensitive for the determination of low levels of heavy metals. Groceries, such as grapes, are collected at industrial process outlets to condense and cut into pieces of about 2 mm. Dried at 80 ° C and passed through a 1 mm sieve as a sample.
