微型光电传感器的水质自动监测仪测定铁
|
摘要
建立了基于光电传感器的水质自动监测仪,对检出限、精密度、准确度、量程范围、零点漂移等性能指标迚行测试,同时测试标准样品、实际水样及加标回收率。结果表明,各项性能指标均满足仪器测试要求;标准样品测定值在保证值范围内,水样的加标回收率为99.5%～108%。该仪器及其监测方法可用于环境突发事件的预警、应急监测和在线监测等领域。
The determination method of iron in water by the automatic monitor with photoelectric sensor was established. The performance indexes of the method including the detection limit, precision, accuracy, measurement range and zero drift were tested. The standard sample and actual water sample were determined by the method, and the standard recovery rate was tested. The results indicated that all the performance indexes met the requirements of instrument testing, the laboratory test result of iron certified reference material was in the permission range, the recoveries of water samples ranged from 99.5% to 108%.The miniature photoelectric automatic monitoring instrument and the determination method are suitable for early warning, emergency monitoring and on-line monitoring of environmental emergencies.
