摘要
提出了水质凯氏氮标准样品的研究方法。在研究过程中 ,完成了样品的配制、均匀性、稳定性等工作。经过多家实验室协作定值 ,确定了样品的标准值及不确定度 。
Research methods about standard samples of water quality determination of Kjeldahl nitrogen were put forward. During the research, works of samples′ make up, homogeneity and stableness were done. With the collaborative calibration of several laboratories, the standard value and uncertainty were determined.
