不同消解方法在测定样品中重金属含量的应用

Application of Different Digestion Methods in the Determination of Heavy Metal Content in Samples

介绍了在测定土壤样品、油脂类样品、植物类样品中重金属含量的多种消解方法,主要包括微波消解法、湿法消解、干灰化法三种方法。通过比较三种方法的优缺点,微波消解法因其快速、准确的特点成为实验中消解样品的最优选择。但在实验时,也应考虑待测样品及元素的性质来确定使用的消解方法。

Some digestion methods while determining the heavy metal content in soil,oil,or some plants are introduced,including microwave digestion,wet digestion,and dry ashing. By comparing the advantages and disadvantages of three methods,microwave digestion is the best choice because of its speediness and accuracy. But in the experiment,we should also consider the nature of the sample and the element to de-termine the used method.
