摘　　要：本文选取市售主流的反渗透净水器,将渗透净水器新机充水,让滤芯及管道充分浸泡24小时后,对水样中邻苯二甲酸酯类物质的含量进行测定,同时,按照厂家说明书条件,在净水器额定净水量下,测定不同净水量时邻苯二甲酸酯类物质的含量,选取了17种邻苯二甲酸酯类物质为目标物,用气相色谱质谱联用仪测定。结果显示,经过浸泡后的水样和在额定净水量下各个体积的水样中17种邻苯二甲酸酯均未检出。说明按照厂家说明书条件下,正常使用反渗透净水器没有发生邻苯二甲酸类物质的迁移。This paper selects the mainstream reverse osmosis water purifier on the market and fills the new machine of the reverse osmosis water purifier with water.After the filter element and pipe were soaked for 24 hours,the content of phthalates in the water sample was determined.At the same time,the content of phthalates was determined under the rated net water amount of the water purifier according to the manufacturer's instructions.17 kinds of phthalates were selected as the target material and determined by gas chromatography and mass spectrometry.Results No 17 kinds of phthalates were detected in the water samples of the reverse osmosis purifier after soaking and in the water samples of each volume under the rated net water volume.According to the manufacturer's instructions,the normal use of reverse osmosis water purifier does not occur the migration of phthalates.
