Determination of 27 Elements in Subway Conditioning Cooling Water by Super Microwave Digestion Inductively Coupled Plasma Mass Spectrometry
The purpose of this study is to establish a detection method for 27 elements in subway air-conditioning cooling water using super microwave digestion-inductively coupled plasma mass spectrometry(ICP-MS).Methods:The samples were digested and processed using a super microwave digestion instrument,and the internal standard method was adopted for method optimization and evaluation.Results:All the elements to be tested showed good linear relationships within the measurement range,with correlation coefficients all greater than 0.998.The average recovery rate ranged from 81.7%to 119%,and the relative standard deviation ranged from 0.02%to 2.39%.Conclusion:This method is simple,efficient,and accurate,suitable for the detection of 27 elements in subway air-conditioning cooling water,and provides more scientific technical support for studying the effects of metal elements in circulating cooling water on corrosion,scaling,and environmental protection of subway air-conditioning systems.
