Abstract

In the present study, the development of innovative polyurethane-polyaniline/TiO modified floating materials applied in the sorption and photodegradation of rhodamine B from water matrix under solar light irradiation is reported. All the materials were fabricated with inexpensive and easy approaches and were properly characterized. The effect of the kind of polyaniline (PANI) dopant on the materials' behavior was investigated, as well as the role of the conducting polymer in the pollutant abatement on the basis of its physico-chemical characteristics. Rhodamine B is removed by adsorption and/or photodegradation processes depending on the type of doping agent used for PANI protonation. The best materials were subjected to recycle tests in order to demonstrate their stability under the reaction conditions. The main transformation products formed during the photodegradation process were identified by ultraperformance liquid chromatography-mass spectrometry (UPLC/MS). The results demonstrated that photoactive floating PANI/TiO composites are useful alternatives to common powder photocatalysts for the degradation of cationic dyes.

摘要

在本研究中，报道了创新的聚氨酯 - 聚苯胺/TiO改性漂浮材料的开发，该材料用于在太阳光照射下从水相中吸附和光降解罗丹明B。所有材料均采用廉价且简便的方法制备，并进行了适当的表征。研究了聚苯胺（PANI）掺杂剂种类对材料性能的影响，以及基于其物理化学特性，导电聚合物在污染物去除中的作用。根据用于PANI质子化的掺杂剂类型，罗丹明B通过吸附和/或光降解过程被去除。对最佳材料进行了循环测试，以证明其在反应条件下的稳定性。通过超高效液相色谱 - 质谱联用（UPLC/MS）鉴定了光降解过程中形成的主要转化产物。结果表明，光活性漂浮PANI/TiO复合材料是用于降解阳离子染料的普通粉末光催化剂的有用替代品。
