Phthalic acid esters are widely used in the many fields of industry. So many countries including China have come to pay attention to them and make up the codes for limiting the content in some products such as textile. By combining international codes, the thesis selects coating and textile that have close relative with people as objections. The research results are as follows:1. The thesis has established the textiles preparation method by a series of experimentations such as extraction solvent, extraction time, solid-phase extraction. The average recoveries of eleven phthalates are from 80.30% to 98.00%, and the relative standard deviations from 0.59% to 2.56%, the results show that this method is accurate and credible.2. The thesis set up the simultaneous determination of benzene, toluene, xylenes and phthalates in coatings.
