Detection system for detecting polychlorophenol in dye

Abstract

The invention discloses a detection system for detecting polychlorophenol in a dye. The detection system comprises a shell and a working cavity which is defined in the shell; a rotatable connecting shaft is arranged in the working cavity; the upper end of the connecting shaft is rotationally provided with a shaft mounting block; the upper side of the connecting shaft is provided with a rotary disc; the lower end surface of the rotary disc is provided with a buffer cavity with a downward opening; the shaft mounting block is located in the buffer cavity; and a buffer spring is connected between the shaft mounting block and the inner wall of the buffer cavity. With the detection system of the invention adopted, the automation of extraction steps in a polychlorophenol detection process is realized, and a potassium carbonate solution can be automatically added into the dye, and therefore, such addition mode can improve accuracy compared with a manual addition mode; the success of subsequent detection is ensured; and detection accuracy is improved. According to the detection system of the invention, after the potassium carbonate solution is added, oscillation can be automatically carried out, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of polychlorinated phenol detection, in particular to a detection system for polychlorinated phenol in dyes. Background technique [0002] Chlorophenol is an important preservative, which can prevent the growth of fungi and inhibit the corrosion of bacteria. The detection method of polychlorophenol in dyes is basically tested according to the national standard GB / T24166-2009. The principle is to use carbonic acid The potassium solution is mixed with the dye, extracted, then acetylated, and finally the result is obtained through chromatographic analysis. At this stage, this process is generally completed by people, and the efficiency is low. Moreover, during the extraction process, the amount of potassium carbonate solution added It is relatively accurate, and there is a certain degree of uncertainty in the manual operation. In view of the above problems, the present invention has made improvements. Content...
