摘要
建立了一种快速、高效、准确的测定印染废水中三氯生的分散固相萃取．高效液相色谱分析方法。样品经聚酰胺粉末吸附和富集后，用5％氨水甲醇洗脱，考察了聚酰胺粉末吸附和富集的时间、吸附剂用量等因素对三氯生回收率的影响。结果显示，三氯生在0．05—5．0mg／L的质量浓度范围内呈良好的线性关系，最低检出限LOD为0．01mg／L，定量检出限LOQ为0．05mg／L，方法回收率在93．O％～101．5％之间，RSD为5．4％～8．3％，能满足印染废水中三氯生的测定要求。
A rapid, efficient and accurate determination method of triclosan in dyeing effluents by dispersive solid-phase extrac- tion （dSPE） and high performance liquid chromatography（HPLC） is developed. The samples are adsorbed and enriched by polyamide powder, and eluted by 5% of ammonia in methanol. The influences of adsorption time and the dosage of polyamide powder on the recovery of triclosan are studied. The results show that triclosan presents a good linear relationship in the range of O. 05 ~ 5.0 mg/L with 0. 01 mg/L the limit of detection,0O. 05 mg/L of the limit of quantification, as well as 93.0% - 101.5% of the extraction recoveries and 5.4% -8.3% of the RSD, which can meet the requirements for determination of triclosan in dyeing effluents.
