Compared with conventional laboratory chemical analysis, ion selective electrode (ISE) is time-saving, low-cost, ease of use and pollution-free. To detect soil nitrate nitrogen content rapidly, a nitrate ion selective electrode could be used. This paper studied characteristics of nitrate ISE. Potentiometric experiments utilizing nitrate ISE to measure sodium nitrate solution were conducted during...
In the agricultural production, recently there are some problems in the determination of the amount of soil nitrate nitrogen using ion selective electrode such as low accuracy and long detection time. The research on measurement model of soil nitrate nitrogen based on ion selective electrode is carried out in this article aiming to obtain the information of soil nitrate nitrogen quickly and accurately...
