摘要
该文指出,甲基橙是一种酸碱指示剂,其分子式:C14H14N2NaO3S,性状为橙黄色粉未或片状结晶,易溶于热水,几乎不溶于乙醇。其分子结构与颜色均随溶液pH值的变化而变化,它具有相对较高的毒性、复杂的结构和难于生物降解性,因此在降解甲基橙溶液有机废水处理中具有典型意义。该文着重介绍了纳米氯化银胶体的光催化降解性能。
The article points out that the methyl orange is an acid-base indicator.Its structural formula is C14H14N2NaO3S.The character is the orange yellow powder or lamellar crystal easy dissolved into the hot water,but hardly dissolved into ethanol.Its molecule structure and color change with the variety of the dissolving pH value.It has the relatively higher toxicity,the complicated structure and hard-biodegradability.Therefore,it has the typical significance in the degradation of methyl orange solution organic wastewater treatment.
