中文摘要: |
建立了便携式分光光度法现场快速测定滨海电厂温排水中余氯的方法。考察了海水样品中pH、盐度和悬浮物等干扰因子对测定结果的影响。结果表明:悬浮物是影响测定准确性的主要因子;絮凝法可以较好的去除悬浮物在测定过程中的干扰。经验证该方法精密度和准确度较好,可作为国标法的重要技术补充,适用于滨海电厂温排水中余氯现场快速监测及应急监测。 |
英文摘要: |
The method of rapid determination of residual chlorine in warm drainage from coastal power plants was established. The effects of pH, salinity and suspended material on the determination results were investigated. The results showed that suspended material was the main factor affecting the accuracy of determination. Flocculation method can remove the disturbance of suspended material in the process of determination. It is of high stability and good accuracy which can be used as an important technical supplement to the national standard and is applicable to rapid monitoring and emergency monitoring of residual chlorine in warm water from coastal power plants. |
