真空检测管-电子比色法快速测定苯胺的应用研究

The Application and Research on the Determination of Aniline By Vaccum Testing Tube-electric Colorimeter

快检技术是当前环境监测工作的重要部分。本文以苯胺为例,得出此方法检出限为0.04mg/L,测定范围是0.15～2.00mg/L,相对标准偏差为0.23%～1.45%,相对误差为-2.63%～4.55%,并用KBC真空检测管-电子比色法测定地表水和废水中的苯胺。结果表明,测定地表水时,测定结果的加标回收率为94%～110%,测定废水时,测定结果的加标回收率为88%～115%,说明该方法操作简单,携带方便,实时快速。

Fast inspection technology is an important part of environmental monitoring. Taking aniline as an example, the detection limit of this method was 0.04mg/L, the determination range was 0.15 ~ 2.00mg/L, the relative standard deviation was 0.23%~ 1.45%, and the relative error was-2.63%~ 4.55%. Aniline in surface water and wastewater was determined by KBC vacuum detection tube-electronic colorimetry. The results showed that the recovery of standard addition was 94%~ 110% in the determination of surface water and 88%~ 115% in the determination of wastewater. It showed that the method was simple, portable and real-time.
