应用Technicon自动分析仪测定了0-400 [μ]g NO[图像]-N/1。在海水中。样品与pH6的乙二胺四乙酸试剂混合。5 - 7。0，并通过含有镉屑的线圈。所得亚硝酸盐的产率为~75%，用Bendschneider和Robinson法测定。在此过程中，亚硝酸盐本身被减少到~5%的程度，并且可以允许其存在。每小时可处理约30个样品。该方法在200 [mu]g NO-3-N/1水平下的变异系数为1.6%。摘要作者：作者
A Technicon AutoAnalyzer has been applied to the determination of 0-400 [mu]g NO[image]-N/1. in sea water. The sample is mixed with an ethylenediamine tetraacetic acid reagnet of pH6. 5-7. 0 and passed through a coil containing cadmium filings. The resultant nitrite, which is formed in ~75% yield is determined by Bendschneider and Robinson's method. Nitrite itself is reduced to an extent of ~5% during the process, and allowance may be made for its presence. About 30 samples per hour can be processed. The method gave a coefficient of variation of 1.6% at a level of 200 [mu]g NO-3-N/1. || ABSTRACT AUTHORS: Authors
