Rapid precleaning method for detecting dioxins

The invention relates to the field of analytical chemistry, and specifically relates to a rapid precleaning method for detecting dioxins. According to the rapid precleaning method disclosed by the invention, activated carbon produced by Wako company is selected as filler, a concentrated solution or liquid sample is dissolved by using 50 ml of acetone/n-hexane (the volume ratio of acetone to n-hexane is 9:1), and toluene is taken as eluent. In such a way, dioxin-like compounds in fish oil and fat-soluble vitamin products can be effectively separated in a short period, thereby achieving the purpose of cleaning. The method disclosed by the invention can completely replace previous processing methods implemented relying on the carbonization of a concentrated sulfuric acid, and the processing cycle of the steps is shortened from 2-3 days in the past to 3-6 hours, thus the processing efficiency is greatly improved, and the detecting cycle of the samples is shortened. Meanwhile, the detection ...
