摘　　要：建立了建筑用胶中苯系物和邻苯二甲酸酯类增塑剂等10种物质同时测定的气相色谱质谱法,对提取方法及色谱条件进行了研究,各物质的检出限在0.2～0.8 mg/L之间。在两个添加水平下,水基型和溶剂型建筑用胶中苯系物及邻苯二甲酸酯类增塑剂的回收率在98.1%～101.5%之间。5个实验室间对相同建筑用胶样品测定的相对标准偏差在1.9%～3.9%之间。A method was developed for determination of benzene homologues and phthalic acid esters（PAEs） in adhesives used in building by GC-MS.Extraction and chromatographic conditions were studied.The detection limit of this method for target compounds were between 0.2 mg/L and 0.8 mg/L.The recoveries of target compounds in solvent type and water type adhesives ranged from 98.1% to 101.5% with two addition levels.The relative standard deviations among 5 laboratories were between 1.9% and 3.9%.
