Automatic pretreatment equipment for detecting banned azo dye in textiles and leather

Abstract

The invention relates to the technical field of drug test, and discloses automatic pretreatment equipment for detecting banned azo dye in textiles and leather. The automatic pretreatment equipment for detecting banned azo dye in textiles and leather comprises at least one set of extraction modules for extracting and collecting samples and a control module which is connected with a peristaltic pump and is used for controlling the flow rate, the flow speed and the preset time program of solvents, wherein each extraction module is respectively connected with the peristaltic pump module for conveying the solvents for extraction to the extraction modules. The automatic pretreatment equipment for detecting banned azo dye in textiles and leather can ensure that the operation of the pretreatment process of the detection of the banned azo dye in the textiles and leather is more convenient and fast, lowers the operation differences of experiment operators, improves the repeatability of the test process and result, and improves the detection accuracy and precision.

Description

technical field [0001] The invention relates to the technical field of textile and leather testing, and more specifically relates to an automatic pretreatment device for detecting prohibited azo dyes in textiles and leather. Background technique [0002] Since the 1980s, the possible harmful substances in textiles and leather and their impact on human health and the environment have received widespread attention in many countries. Germany's MAK (Maximum Arbeitplaz Konzentrations, maximum concentration in the workplace) committee pointed out that the azo dyes made of carcinogenic aromatic amines are prone to bioreduction by the action of intestinal bacteria and enzymes in the human body, so that the azo dyes are cleaved to release carcinogenic aromatic amines, produce carcinogenic activity. On April 10, 1992, Germany promulgated the "Food and Daily Consumer Goods Law", which clearly pointed out that 15 kinds of dyes synthesized by carcinogenic aromatic amines were prohibited...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in the pretreatment of samples that prohibit the detection of azo dyes in textiles and leather, it is necessary to use solvents such as diethyl ether to extract the substances to be determined multiple times. The addition of solvents is mostly done manually, and the difference in the amount and speed of addition will cause deviations in the final test results; low boiling point solvents such as ether are extremely volatile in the open operation during the extraction process, resulting in ether vapor concentration in the workplace High; multiple manual liquid addition and extraction operations took up a lot of working time of inspectors
