Problems solved by technology

Due to the differences in biological individual factors, there are huge differences in the nutrient concentration and toxic concentration of cobalt in the body. At present, there is no good detection and analysis method for inorganic cobalt. Therefore, it is extremely necessary to establish a fast, accurate, convenient and economical detection method. , which is conducive to monitoring the content and usage of inorganic cobalt in biochemicals, food, and feed, so as to ensure human health and animal husbandry safety

Embodiment 1

[0028] Example 1, precision and recovery detection of inorganic cobalt content in animal tissue samples:

[0029] Fresh sample of animal tissue was beaten, weighed 5.0015g (accurately weighed to 0.0001g) into a 25ml graduated colorimetric tube with stopper, added 12% hydrochloric acid aqueous solution to the mark and mixed evenly. Place in a water bath at 90°C for 4 to 8 hours, vibrate continuously during this period to fully extract the sample, take it out and cool it and filter it with a 0.45 μm filter membrane, test the filtrate on the machine, and do a blank test at the same time.

[0030] Use Co standard stock solution: single element solution component analysis standard substance cobalt, 1000mg / L, medium 5% HCl; prepare Co working solution, concentration gradient 0.0mg / L, 0.01mg / L, 0.05mg / L, 0.1mg / L , 0.5mg / L, 1.0mg / L: 5% HCl medium.

[0031] The detection instrument is the existing THERM0 iCAP6300 inductively coupled plasma atomic emission spectrometer;

[0032] The d...

Embodiment 2

[0050] Embodiment 2, the precision and recovery rate detection of inorganic cobalt content in animal feed:

[0051] Weigh 5.1020g of the sample to be tested after drying and crushing through a 80-mesh sieve (accurately weighed to 0.0001g), put it in a 25ml graduated colorimetric tube with stopper, add 12% hydrochloric acid aqueous solution to the mark and mix well, place at 90°C In the water bath for 4 hours to 8 hours, during which it kept shaking to fully extract the sample, take it out for cooling and filtration, test the filtrate on the machine, and do a blank test at the same time.

[0052] Use Co standard stock solution: single element solution component analysis standard substance cobalt, 1000mg / L, medium 5% HCl; prepare Co working solution, concentration gradient 0.0mg / L, 0.1mg / L, 0.5mg / L, 1.0mg / L , 5.0mg / L, 10.0mg / L: 5% HCl medium.

[0053] The detection instrument is the existing THERMO iCAP6300 inductively coupled plasma atomic emission spectrometer:

Abstract

The invention relates to a method for determining inorganic cobalt in biological chemicals, food and feedstuff through an inductively coupled plasma atomic emission spectrometer. 2 percent of a hydrochloric acid water solution and 12 percent of the hydrochloric acid water solution are added into samples to be tested; the inorganic cobalt is extracted in a form of chloride under dilute hydrochloric acid conditions after water bath and oscillation leaching; and then the inductively coupled plasma atomic emission spectrometer is used for determining a sample treatment liquid. The detection of the content of the inorganic cobalt in the biological chemicals, the food and the feedstuff by the method is quick and effective, and the relative average deviation is less than 5 percent; therefore, the method provides a reliable method with reliable and convenient implementation for detecting the content of the inorganic cobalt in the biological chemicals, the food and the feedstuff, and can meet the requirement in the research and production.

Description

technical field [0001] The invention relates to a method for measuring inorganic cobalt in biochemicals, food and feed, in particular to a method for detecting the content of inorganic cobalt in biochemicals, food and feed through an inductively coupled plasma atomic emission spectrometer. Background technique [0002] Cobalt can exist in different chemical forms, including organic cobalt and inorganic cobalt, and inorganic cobalt is the total amount of cobalt in the form of inorganic cobalt compounds. The International Cancer Agency (IARC) has listed cobalt and its compounds as suspected human carcinogens. Like other trace elements, excessive cobalt in animal feed, traditional Chinese medicine, and human food may inhibit the growth of the body and even cause serious poisoning accidents. The toxic effects of cobalt are mainly manifested as polycythemia, goiter, cardiomyopathy, pancreas and nervous system damage. Inorganic cobalt in food can be absorbed in the small intesti...
