摘　　要：以典型的偶氮染料酸性大红3R作为研究对象,采用铁柱撑改性膨润土-Fenton氧化法联合对模拟染料废水进行处理。利用UV、IR、GC-MS等谱图分析手段来研究铁柱撑改性膨润土-Fenton氧化体系降解酸性大红3R的降解历程。对各种谱图的综合分析证明,经处理后的染料分子,其偶氮共轭发色体系完全被破坏,萘环发生开环反应。通过对各种谱图的解析,并结合相关资料,推测出了染料酸性大红3R的降解历程。In this dissertation, the acid brilliant scarlet 3R was chosen as research object. Experimental research has been operated in degradation of simulative dyestuff wastewater with the Fe pillared bentonite and Fenton oxidation joint application. The degradation pathways of the acid brilliant scarlet 3R dye wastewater with Fe -modified bentonite -Fenton oxidation in joint application have been studied by using UV, IR and GC - MS Spectra analysis. The azo conjugate chromogenic system of acid brilliant scarlet 3R molecular was completely destroyed, with the naphthalene ring - opening reaction. The acid brilliant scarlet 3R dye degradation process was surmised based on the comprehensive analysis of various spectrum garaph.
