Determination of Tetrabromobosphenol S in Textiles by High Performance Liquid Chromatography
A magnetic solid phase extraction method for tetrabromobisphenol S in textiles was developed and then analyzed by high performance liquid chromatography.In the experiment,Fe3O4-GO magnetic material was used as the magnetic solid phase adsorbent,and orthogonal test was used to optimize the extraction agent dosage,temperature and time during the extraction process.Then 0.1 mmol formic acid/acetonitrile(V∶V=30∶70)was used as mobile phase,and the detection wavelength was 214 nm by Athena C18-WP column(2.1 mm×100.0 mm,5.00 μm).Quantitative by external standard method.The results showed that in the range of 0.01 mg/L to 50.00 mg/L,the S linearity of tetrabromobisphenol was good,the correlation coefficient R2＞0.999,the recoveries were 98.6％～101.5％,and the relative standard deviation(RSD)was less than 5.0％(n=6).The method is efficient,simple and sensitive,and can satisfy the detection of tetrabrombisphenol S in textiles.
