Abstract
对3种典型酚类内分泌干扰物——双酚A(BPA)、辛基酚(OP)和壬基酚(NP)由水相到半透膜被动采样装置(SPMD)的富集动力学进行了实验室研究。研究发现，SPMD对OP和NP具有较好的富集效果，而对于BPA的富集能力较低。在4 ℃条件下，20 d内3种物质在水相和SPMD相间未达到分配平衡，而在15和25 ℃时，OP和NP可分别在3~15 d内达到分配平衡。将目标化合物的SPMD和水相分配平衡常数KSPMD实测值与经验计算值进行比较表明，二者之间存在较大偏差。改变水溶液pH值、碱度和硬度条件，观察其对目标化合物在SPMD相中的一日富集质量浓度ρs,1 d的影响。结果表明，在高pH值条件下，酚类目标污染物的离子化可导致其ρs,1 d的降低，而溶液碱度和硬度则对富集速率无显著影响。
