Then, the adsorption ability of cucurbituril membrane to triclosan and triclocarban was studied, and finally, the feasibility of cucurbituril membrane as a passive sampling technology for measuring triclosan and triclocarban. Results comfirmed that the cucurbituril molecules were introduced into the cellulose acetate membrane. Moreover, comparing with the cellulose acetate membrane, the cucurbituril membrane has stronger thermal stability and adsorption property. Taking the cucurbituril membrane as the binding phase of a passive sampler, it was proved that the passive sampler has good performance in different environmental factors (i.e., pH values, ion strength and dissolved organic matter). Finally, the sampler was deployed into two sites of Qinhuai River in Nanjing, and the field test verified the feasibility of the passive sampler in measuring TCS and TCC in water. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
