Abstract

The invention discloses a modified colloidal gold preparation method and a gold-labeled antibody preparation method, and further discloses a colloidal gold immunochromatography kit, a heavy metal quantitative detecting system with the kit, and a method for quantitatively detecting heavy metal. A gold-labeled antibody formed by modified colloidal gold and an antibody is stable and is not influenced by the acid environment; when the immunochromatography kit is prepared from the modified colloidal gold, in the acid conditions, heavy metal can still be accurately detected in an oriented mode, traditional atomic absorption spectrometry can be replaced, cost is low, and application prospects are good.

Description

technical field

[0001] The invention relates to a heavy metal quantitative detection system and a method for quantitative detection of heavy metals. Background technique

[0002] With the rapid development of our country's economy and the improvement of living standards, people have higher requirements for food safety. serious. There are many reasons for food safety problems, and the problem of excessive heavy metals is one of the important factors affecting food safety. At present, heavy metals such as copper, lead, zinc, iron, cobalt, nickel, manganese, cadmium, mercury, tungsten, molybdenum, gold, silver, etc. The heavy metals that are harmful to our humans and the environment at this stage include the following elements: mercury, cadmium, lead, chromium, copper, and metalloid arsenic and other heavy metal elements with significant biological toxicity.

[0003] If heavy metal elements are directly discharged into rivers, lakes or seas without treatment, or enter the so...
