采用高效液相色谱法,建立了检测纺织品中17种邻苯二甲酸酯类增塑剂含量的方法.采用苯基柱(4.6 mm×25 mm,5μm),流速为1.0 mL/min,以水与乙腈为流动相,梯度洗脱,保留时间定性,外标法定量.方法最低限5 mg/kg,以标准加入法计算回收率,在5~20 mg/kg添加范围内,回收率为80%~110%,相对标准偏差(RSD)为1.16%~6.17%.
채용고효액상색보법,건립료검측방직품중17충린분이갑산지류증소제함량적방법.채용분기주(4.6 mm×25 mm,5μm),류속위1.0 mL/min,이수여을정위류동상,제도세탈,보류시간정성,외표법정량.방법최저한5 mg/kg,이표준가입법계산회수솔,재5~20 mg/kg첨가범위내,회수솔위80%~110%,상대표준편차(RSD)위1.16%~6.17%.
A determination method of 17 phthalate plasticizers in textiles by high performance liquid chro?matography was established. The phenyl column (4.6 mm × 25 mm, 5 μm) was used with water and acetoni?trile as the mobile phase. The flow rate was 1.0 mL/min at gradient elution, the analysis was qualitative by re?tention and quantified by peak area using external standard method. The quantitative limit of this method was 5 mg/kg, the recovery rate tested by standard addition method was in the range of 80%~110%, and the rela?tive standard deviation was in the range of 1.16%~6.17%at a spiking level from 5~20 mg/kg.
