电气石吸附降解亚甲基蓝等有机染料的研究

Absorption and Degradation of Organic Dyestuff Like Methylene Blue by Tourmaline

电气石用苯丙乳液复合成膜,处理亚甲基蓝、甲基橙、刚果红和乙基紫四种有机染料水溶液。用紫外-可见分光光度法对电气石处理后的溶液分析,把溶液烘干,用红外光谱法对溶液干燥后的残留物分析,对不同条件下亚甲基蓝溶液浓度-时间曲线进行比较,结果表明,电气石对一些有机染料有降解作用,能够二次利用。最后初步讨论了电气石降解有机染料的机理。

Tourmaline was composed with styrene-acrylic emulsion to deal with some organic dyestuff aqueous solution such as methylene blue, methyl orange, ethyl violet and congo red. The dealt solution and leftover of dried solution were analyzed by ultraviolet-visible spectrophotometry and infrared spectrometry, and the concentration of methylene blue solution decreased with time in different cases. The results show that some organic dyestuff could be degraded by tourmaline and tourmaline can be used repeatedly. The
