Embodiment 1

[0018] The method for simultaneously determining arsenic and antimony in the traditional Chinese medicine Acanthopanax senticosus, sample processing: Accurately weigh the samples to be tested of Acanthopanax senticosus plants or series products of Acanthopanax senticosus, place them in the inner tank of microwave digestion, add digestion: liquid nitric acid and over The mixed solution of hydrogen oxide, with a volume ratio of 5:1, is put into the outer tank, and the outer tank cover is tightened, and placed in the microwave digestion system. According to the set optimal working conditions, until the digestion is complete, cool down, dilute to a 25mL stoppered colorimetric tube pre-added with 2.0mL hydrochloric acid and 2.0mL thiourea, and measure by atomic fluorescence method.

Embodiment 2

[0023] A method for simultaneously measuring arsenic and antimony in the Chinese medicine Acanthopanax senticosus described in Example 1, the drawing of the arsenic and antimony working curve: first dilute the arsenic standard solution GBW(E)080390 10 times, pipette 1.0mL of the diluted arsenic Put the standard solution and 1.0mL antimony standard solution GBW(E)080545 in a 100mL volumetric flask, add 10mL hydrogen chloride HCl in advance, and use ultrapure water to make up the volume, which is 10μg?mL -1 Arsenic and antimony mixed standard stock solution. Take this solution and dilute to 0.1μg?mL -1 , made of mixed standard solution of arsenic and antimony. Draw 0.0, 0.5, 1.0, 2.0, 4.0, 5.0mL of arsenic-antimony mixed standard solution respectively, and set the volume to a 50mL colorimetric tube. Add 5.0mL hydrogen chloride HCl and 10.0mL thiourea to the colorimetric tube in advance to obtain a concentration of 0.0 , 1.0, 2.0, 4.0, 8.0, 10.0 μg?L -1 Mixed standard solution...

Abstract

The invention relates to a method for simultaneously measuring arsenic and stibium in Chinese medicinal manyprickle acathopanax root. In recent years, hazards of heavy metal to the health and safety of a human body draw great attention of countries in the world and many countries raise strict requirement on the content of imported Chinese medicinal heavy metal. Heavy metal pollution of Chinese medicaments becomes a key barrier for the Chinese medicament to go to the world and enter international medicament market. The method comprises sample treatment which comprises the following steps: correctly weighing a sample to be measured of a manyprickle acathopanax root plant or a manyprickle acathopanax root series of product; putting the sample to be measured in a microwave digestion inner tank; adding digestion solution into the inner tank; putting the inner tank into an outer tank and sealing the outer tank; putting the outer tank into a microwave digestion system to perform digestion; cooling the outer tank; fixing the volume of the solution and pouring the constant volume solution into a 25 mL color comparison tube with a stopper into which 2.0 mL of hydrochloric acid and 2.0 mL ofthiourea are added in advance; measuring by an atomic fluorescence method; and drawing working curves of the arsenic and stibium. The method is used for measuring the content of the arsenic and stibium in Chinese medicinal manyprickle acathopanax root.

Description

Technical field: [0001] The invention relates to a method for simultaneous determination of arsenic and antimony in traditional Chinese medicine Acanthopanax by using microwave digestion-hydride generation-atomic fluorescence method. Background technique: [0002] At present, many experts and scholars at home and abroad are mostly devoted to the research on the chemical constituents and pharmacological effects of Acanthopanax senticosus, but there is no report on the research on its heavy metal content. In recent years, the harm of heavy metals to human health and safety has attracted great attention from all over the world, and many countries have put forward strict requirements on the content of heavy metals in imported traditional Chinese medicines. The heavy metal pollution of Chinese medicinal materials has become an important obstacle restricting Chinese traditional medicine from going to the world and entering the international pharmaceutical market. Therefore, it is...
