| 摘 要： | 6mmol/L磷酸钠、10mmol/L硼砂、25mmol/L十二烷基磺酸钠组成的pH9 6的缓冲溶液作电泳液,UV检测波长227nm,测定了印染废水中分散蓝2BLN的含量。结果表明:进样量在0～0.4g/L范围内线性关系良好(r=0.9973),加样回收率为98.60%,RSD为1.56%,测得印染废水中分散蓝2BLN的含量为0.074g/L。本法简便,快速,可作为印染废水中分散蓝2BLN的含量的测定方法。

Determination of disperse blue 2BLN in dyeing wastewater by capillary electrophoresis |
| |
| Abstract: | The pH 9.6 buffer comprised 6 mmol/L sodium phosphate, 10 mmol/L sodium borate, 25 mmol/L sodium dodecyl sulphate is used as runing solution, and UV detection wavelength is at 227 nm to determining disperse blue 2BLN in dyeing wastewater. The results showed that the linear range of calibration curve was from 0～0.4 g/L with a correlation coefficient of 0.997 3, and the average recovery 98.60% with RSD was 1.56%. The concertration of C.I. disperse blue 2BLN in dyeing wastewater determined by this method was 0.074 g/L.The method is accurate and fast, and can be a measure in determining disperse blue 2BLN in dyeing wastewater. |
