Abstract:

Since Bisphenlo A (BPA) can interfere with the endocrine function of the organism, causing all kinds of reproductive abnormalities. At the same time, BPA also gas a certain embryonic toxicity and produce teratogenetic and carcinogenic effects, threatening the health of the fetus. It is necessary to test BPA in textiles. BPA is used as the dyeing and finishing auxiliaries in the textiles, and has certain harm to the health of textile users. In the light of the biological hazards of BPA in textiles, it adopts surface plasmon resonance (SPR) to perform the qualitative and quanlitative and quantitativedetection of BPA. The practicability of SPR technology in the detection of BPA was explored from four aspects, such as chip modification, determination of the optimum concentration of BPA-BSA solution, the response of BPA with different concentrations and the extraction of BPA in textiles. SPR detection method of BPA has advantages of high detection speed, strong pertinence and high detection sensitivity and low requirements on the samole, is applicable in the detection field, and can be used in the determination of the biphenol A content in textiles.
