| 中文摘要 |
| 对地下水中一种染料中间体H酸(4-氨基-5-羟基-2,7-萘二磺酸)的污染进行了提取、分离、碱熔融试验,并与已知可能的污染物进行薄层色谱和红外光谱对照分析,确定该地下水中棕红色污染物为H酸长期氧化的衍生产物。 |
| 英文摘要 |
| The brown red pollutants in underground water derived from a dyestuff intermediate-H acid(4-amino-5-hydroxy-2,7-naphthalene disulfonic acid) were extracted by means of reduced pressure concentration, column chromatographic separation. The extracted pollutants were primarily tested by alkali fussion, and then undertaken the comparative analysis between the pollutants and some standard samples which were selected as possible pollutants in the light of the actual conditions. According to the thin layer chromatography and IR spectrometry of them. It can be established that the brown red pollutants were the derivatives of H acid oxidized by air for a period of time in underground water. |
