The cost of raw materials can be saved by the aid of the device.

Description

technical field [0001] The invention relates to the technical field of spectral analysis, and more specifically, to a microwave-assisted on-line detection device for heavy metals in feed and a microwave-assisted on-line detection method for heavy metals in feed used in the above device. Background technique [0002] In recent years, my country's animal husbandry industry has developed rapidly, and the feed processing industry has played a decisive role in the development of animal husbandry and the health of animal products. At present, heavy metal elements copper (Cu), cadmium (Cd), chromium (Cr), Lead (Pb) has been widely used in animal feed. Although putting in a proper amount of heavy metal elements at the corresponding stage can promote the growth of poultry and livestock, if the content of heavy metals exceeds the standard, it may cause toxic and side effects such as lesions in livestock and poultry. It is difficult to decompose These heavy metal elements are enriched in...
