In-vitro detection method for microelement forms in metal concentrate

Abstract

The invention provides an in-vitro detection method for forms of micro-elements in metal concentrate, which specifically comprises the following steps: respectively measuring the contents of the micro-elements in the concentrate by adopting an X-ray fluorescence spectrophotometer; according to the measured content of the microelements in the concentrate, preparing a to-be-measured liquid of the microelements; respectively culturing the lung cell line and the stomach cell line in a container which is divided into a top side chamber and a substrate side chamber by a porous membrane; respectively adding the micro-element liquid to be detected into the lung cell line and the stomach cell line, and culturing the whole container in an incubator for 24 hours; collecting samples of the lung cell line and the stomach cell line; respectively measuring the contents of the micro elements of the lung cell line by using inductively coupled plasma mass spectrometry; and respectively determining the contents of different forms of the microelements by using a high performance liquid chromatography and inductively coupled plasma mass spectrometry combined method. According to the method provided by the invention, the content of the micro elements in the metal concentrate in the specific tissues of the human body can be accurately detected, and different forms of the micro elements can be analyzed, so that the damage to the human body can be more accurately evaluated.

Description

technical field [0001] The invention relates to the field of metal concentrate element detection, in particular to an in vitro detection method for trace element forms in metal concentrate. Background technique [0002] Non-ferrous metals are essential basic materials and important strategic materials for national economy, people's daily life, national defense industry, scientific and technological development. Agricultural modernization, industrial modernization, national defense and scientific and technological modernization are all inseparable from non-ferrous metals; the production process of non-ferrous metals usually produces a large amount of waste gas, waste water and waste residues, which contain many useful components, sometimes toxic substances, and some non-ferrous metals also have Toxicity, mostly due to the presence of trace elements such as arsenic and antimony; [0003] At present, the research status of the main content elements of copper concentrate, lead ...

Problems solved by technology

Although there are many methods to analyze the total amount of harmful elements in the above minerals, there is no method to evaluate the damage to the human body caused by the inhalation of trace amounts of harmful substances by sampling personnel during cargo loading and unloading

According to the requirements of "safety, sanitation and environmental protection" in the "Commodity Inspection Law" and "Regulations for the Implementation of the Commodity Inspection Law", this problem needs to be solved urgently; and there is no method to analyze the different forms of harmful elements in the above minerals, so that Further evaluate the impact of trace harmful substances on the degree of damage to the human body
