Automated method for determining nitrate and nitrite in water and soil extracts



Automated method for determining nitrate and nitrite in water and soil extracts



Communications in Soil Science & Plant Analysis 18(6): 625-636



This paper describes an AutoAnalyzer method for measuring nitrate plus nitrite in thirteen commonly used soil extraction solutions. The AutoAnalyzer is normally equipped with a column containing cadmium chips. In this study the column is replaced with a cadmium-silver wire inserted in plastic tubing which has several advantages. There is no compaction of cadmium chips, it eliminates the need to debubble the sample stream before it enters the reductor, the dead volume is decreased, and it eliminates the copper sulfate treatment process except for one given the first time the wire is used. The method is also excellent for measuring nitrate plus nitrite in rain water.
