摘要:
基于葫芦脲的超分子特性,以醋酸纤维素为载体,制备了葫芦脲膜,采用傅里叶红外光谱、扫描电镜、热重分析对膜的性能进行了表征,研究了葫芦脲膜对三氯生(TCS)和三氯卡班(TCC)的吸附性能,验证了以葫芦脲膜为结合相的被动采样技术测定2种物质的可行性。结果表明:葫芦脲分子确实被引入到醋酸纤维素中,相比于醋酸纤维素膜,葫芦脲膜具有更强的热稳定性和吸附性能;以葫芦脲膜为结合相的被动采样装置在不同环境因素(pH值、离子强度、可溶性有机质)下都具有良好的工作稳定性;将该装置布设到南京市秦淮河中的2个采样点,野外实验验证了该采样装置应用于监测实际水体中的TCS和TCC的可行性。

Preparation of Cucurbituril based Polymer Membrane and Its Application in Water Passive Sampling Technology

Abstract:
Based on the supramolecular property of cucurbituril, this study prepared a cucurbituril membrane by taking the cellulose acetate as carrier, of which the physicochemical property was characterized using the Fourier infrared spectrum, the scanning electron microscope and the thermos gravimetric analysis. 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.
