由于食品中成分较复杂，有机质含量高，基体干扰较大，因而其微量元素测定的成败，一定程度上取决于样品的消化方法。目前我国国标法中食品的消化方法主要有马弗炉干法灰化法和湿法消化法，但两方法均存在耗时，劳动强度大，元素易损失并易造成污染等缺点。近几年来，利用微波? Due to the complexity of the ingredients in the food, the high content of organic matter and the large disturbance of the matrix, the success or failure of the determination of trace elements depends, in part, on the sample digestion method. At present, China’s national standard method of food digestion methods are mainly muffle dry ash method and wet digestion, but both methods exist time-consuming, labor-intensive, easy to lose elements and easy to cause pollution and other shortcomings. In recent years, the use of microwave?
