摘要

印染废水对环境造成严重污染，必须经过处理达到排放标准后方可排放。在这项研究中，我们报道了一种以棉织物为底物，在聚多巴胺（PDA）沉积的辅助下制备纳米零价铁（nZVI）颗粒固定化棉织物（nZVI@cotton）的方法。对棉织物的力学性能进行了测试，结果表明，PDA沉积后棉织物的断裂强度有明显提高。以罗丹明B和Cr（VI）为模型，评价nZVI@cotton织物对污染物的去除能力。在60 min内，罗丹明B的脱色效率可达79.45%,Cr（VI）的去除率可达70.74%。此外，系统考察了铁含量、不同nZVI@cotton织物体系、污染物组成对nZVI@cotton织物可重复利用性的影响。结果表明，PDA辅助制备的nZVI@cotton织物对罗丹明B和Cr（VI）离子去除率高，且易于回收利用，是一种比较理想的废水净化材料。

PDA-assisted immobilization of nZVI on cotton fabric for the removal of rhodamine B and chromium (VI) ion

Printing and dyeing wastewater can cause serious environmental pollutant and must be treated to meet the emission standards before discharge. In this study, we report a method to prepare nano zero-valent iron (nZVI) particle-immobilized cotton (nZVI@cotton) fabrics assisted by polydopamine (PDA) deposition using cotton fabrics as the substrate. The mechanical property tests of cotton fabric revealed a significant improvement in the breaking strength after deposition of PDA. The pollutant removal capability of nZVI@cotton fabric was evaluated using rhodamine B and Cr(VI) as models. The decolorization efficiency of rhodamine B could be up to 79.45% and Cr(VI) removal efficiency was 70.74% within 60 min, respectively. In addition, the iron content, different nZVI@cotton fabric system, the effect of pollutant composition and reusability of nZVI@cotton fabric were systematically investigated. Results showed that nZVI@cotton fabric prepared with the assistance of PDA was a kind of comparable wastewater purification material with the advantages of high removal efficiency to rhodamine B and Cr(VI) ions and easy to be recycled.

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
