摘要
针对测定总氮过程中空白值偏高的问题,重点分析了实验环境、实验用水、试剂、玻璃器皿、消解过程等因素对空白值的影响,并提出减少空白值偏高的相应对策。
Aiming at the problem of high blank value from the detection process of total nitrogen, the factors from test environment, water used, reagents, glass vessel, digestion process and so on were analyzed carefully. In the end, the measures on avoiding the high blank value in the experiment were put forward.
