摘要
运用全自动高锰酸盐指数分析仪来测定水中高锰酸盐指数,与现行方法进行比对,分析了二者之间的优缺点。结果表明:该方法检出限可低至0.2 mg/L,准确度在93.9%-104%,精密度小于6.0%。该方法适用性好,效率高,可大大减少人为误差,提高分析自动化水平,抗干扰强,操作简单,更适合应用于环境监测领域。
The paper uses automatic permanganate index analyzer to determine permanganate index in water.Compared with the current method,the advantages and disadvantages are analyzed.The results show that the detection limit of this method can be as low as 0.2 mg/L.The accuracy is 93.9%-104%,and the precision is less than 6.0%.The application of automatic permanganate index analyzer to determine permanganate index in water has good applicability and high efficiency.It can greatly reduce human error and improve the level of analysis automation,with strong anti-interference and simple operation.It is more suitable for the field of environmental monitoring.
