Abstract
The invention discloses a rapid screening and testing method for various restricted or forbidden compounds in chemical materials. The method comprises the following steps: sampling, pretreatment, anddetection of the types of restricted or forbidden compounds in a pretreated target, wherein the pretreatment process comprises the following steps: mixing a sample, a process monitoring substance andan extractant in a sealed container to form a mixed solution, and continuously performing ultrasonic treatment for first appointed time at first appointed temperature; filtering or centrifugating themixed solution, and obtaining a pretreated solution. According to the rapid screening and testing method for the various restricted or forbidden compounds in the chemical materials, by optimization ofthe pretreatment process of the sample, the number of times of test is reduced, the test efficiency is improved, the number of used equipment is reduced, and the time and labor cost is reduced; a test result is accurate; the number of times of instrument analysis is reduced, and the instrument analysis efficiency and the use efficiency are improved.
Description
technical field [0001] The invention relates to the detection field, in particular to a rapid screening test method for various restricted or banned compounds in chemical raw materials. Background technique [0002] For primary textile raw materials, these 400 kinds of compounds are restricted or banned substances with high concern (the 400 kinds of compounds include alkylphenols, alkylphenol polyoxyethylene ethers, azo dyes, carcinogenic and allergenic dyes, Organochlorine carriers, flame retardants, perfluorinated compounds, chlorophenols, plasticizers, polycyclic aromatic hydrocarbons, pesticide residues, SVHC, volatile organic compounds, etc.), for the purpose of source control pollution, many textile-related manufacturers expect to At the stage of incoming primary raw materials, the pollution or residues are investigated. Although there are corresponding standard test methods for all substances, there are more than a dozen test methods involved. If one is tested one by ...
