铜是肌体必需的微量元素。分析食物中的铜,可以了解铜的来源;分析生物材料中的铜,可以为职业中毒临床和毒理学研究提供科学依据;分析车间空气粉尘,可以弄清环境污染和影响健康的原因.本工作在测定人发的基础上,将双乙醛草酰二腙分光光度法推广应用于测定尿、奶粉、粮食和车间空气粉尘中的铜,试图代替现行分析方法,为研究微量元素与健康提供通用的新方法.
Copper is a necessary trace element of the body. Analysis of copper in food can understand the source of copper; Analysis of copper in biological materials can provide a scientific basis for clinical and toxicological studies of occupational poisoning; Analysis of the workshop air dust can clarify the causes of environmental pollution and health effects. Based on the determination of human hair, diacetaldehyde oxalyl-hydrazone spectrophotometry is widely used in the determination of copper in urine, milk powder, food and workshop air dust in an attempt to replace the existing analytical methods to provide universal for the study of trace elements and health The new method
