The invention discloses a method for determining tetrabromobisphenol S bis-(2,3-dibromopropyl ether) in daily consumer goods. The method comprises the following steps: sampling, pretreatment, and detection for the content of tetrabromobisphenol S bis-(2,3-dibromopropyl ether) in a target after pretreatment. The pretreatment step concretely comprises that a sample is mixed with a first extraction agent to form a first mixed solution, and supersonic treatment is carried continuously in first specific time at first specific temperature; and the first mixed solution is mixed with a second extraction agent to form a second mixed solution, and supersonic treatment is carried continuously in second specific time at second specific temperature. Fewer reagents are used, the environment is protectedmore effectively, and the health of humans is protected more effectively; and the detection limit is low, the method is easy to operate and popularize, a HPLC-DAD analyzer easy to obtain is used as atest instrument, and the method is high in sensitivity and high in anti-interference capability.
Description
technical field [0001] The invention relates to the field of detection, in particular to a method for determining octabromo S ether in a daily consumer product. Background technique [0002] Most light industrial materials such as plastics, rubber, and fibers are combustible. Especially for plastics, if they are to be used in transportation, construction, electrical equipment, aviation, space flight, etc., it is urgent to solve the problem of their combustion resistance. Adding flame retardants to plastic products has become the best solution at present. Generally speaking, organic flame retardant has a good affinity. In plastics, brominated flame retardants occupy an absolute advantage in organic flame retardant systems. Although there are many "criticisms" on environmental protection issues, it has been difficult to have other flame retardant systems. replace. In recent years, the production and consumption of flame retardants in my country have both been favorable, and...
