Problems solved by technology

The study found that the order of toxicity of various forms of arsenic is arsenous acid > arsenic acid > monomethyl arsenic acid > dimethyl arsenic acid, while arsenocholine and arsenobetaine are non-toxic. It can be seen that the toxicity of various arsenic forms is relatively different. Only measuring the arsenic content in tobacco paper cannot objectively and accurately control the toxicity of arsenic in paper materials
Therefore, there is an urgent need for detection and analysis of arsenic species, but there is currently no method for the analysis of arsenic species in tobacco paper

Embodiment 1

[0026] Weigh about 2g of cigarette tipping paper (produced by Zhejiang Hengfeng Paper Mill), and cut it into about 1mm with ceramic scissors 2 Put the sample in a 50mL centrifuge tube with a cover, add 10mL of hydrochloric acid aqueous solution with a pH value of 5, place it on a vortex mixer and vibrate at a speed of 1500r / min for 5min to fully infiltrate the sample, then add 10mL, and the volume ratio is 1: 1 of ethanol-acetone mixture, continue to oscillate on a vortex mixer at a speed of 1500r / min for 10min, after standing still, take the supernatant and filter it through a filter membrane with a pore size of 0.22μm before injecting the sample. High performance liquid chromatography-inductively coupled plasma mass spectrometry (Aglient 1260 high performance liquid chromatography and Aglient 7500 inductively coupled plasma mass spectrometry in the United States) were used for detection, and the results are shown in Table 1.

Abstract

The invention belongs to the field of detection and relates to an extraction and purification method and a detection method of an arsenic form in paper for tobaccos. Particularly, the extraction and purification method comprises a step of adding an acid solution and an alcohol-ketone mixed liquid to a sample. The invention also relates to a combined reagent and an application of the combined reagent in extraction and purification or detection of the arsenic form in the paper for tobaccos. According to the extraction and purification method and the detection method disclosed by the invention, the blank for analyzing the arsenic form in the paper for tobaccos is filled; and the toxicity of arsenic in a paper material can be accurately and objectively controlled.

Description

technical field [0001] The invention belongs to the technical field of substance detection, and relates to an extraction and purification method and a detection method of arsenic form in tobacco paper. The invention also relates to a combined reagent and its use in the extraction, purification or detection of the arsenic form in tobacco paper. Background technique [0002] Tobacco paper includes three types: cigarette paper, filter tip wrapping paper and tipping paper for cigarettes. Among them, cigarette paper is commonly known as coil paper, which is used to wrap tobacco and participate in the burning of cigarettes; filter rod wrapping paper is wrapped on the outside of cigarette filter to support the shaping of filter; tipping paper for cigarettes is also known as tipping paper , is a special packaging paper specially used for connecting filters and cigarettes. The surface of cigarette tipping paper is generally painted with brown or white paint, or in order to improve d...
