锌和钴是人体必不可少的微量元素,糖是人类主要食品之一,糖中锌、钴的含量直接影响人类的健康。以往测定糖品中的微量元素多采用化学法和比色法,这些方法操作复杂,分析时间长,且准确度和灵敏度均不够理想。原子吸收分光光度应用于分析食品中的微量金属元素,其公认的优点是分析速度快,灵敏度高。但样品必须经过手续繁杂费时的预处理。使用原子吸收和火焰发
Zinc and cobalt are essential trace elements of the human body, sugar is one of the main human food, sugar, zinc, cobalt content directly affects human health. The past determination of trace elements in sugar more chemical and colorimetric methods, these methods are complicated to operate, the analysis of a long time, and the accuracy and sensitivity are not ideal. Atomic absorption spectrophotometry used in the analysis of trace metals in food has the recognized advantages of fast analysis and high sensitivity. However, the sample must go through complicated and time-consuming procedures. Use atomic absorption and flame
