摘要
按照GB/T 6920-86的方法对工业废水进行pH测定,分析和讨论了实际操作中仪器的校正、电极的性能、样品温度、空气中CO_2的影响、缓冲溶液的配制、仪器的维护保养等对测定结果的影响。对影响因素进行适当的控制,以保证测量结果的准确性。
According to GB/T6920-86 method for industrial wastewater pH measurement,analysis and discusses the practical operation of instrument calibration,the performance of the electrode,sample temperature,the effect of CO2 in the air,the configuration of the buffer solution,and the instrument maintenance effect on the determination results.The influencing factors are controlled appropriately to ensure the accuracy of the measurement results.
