Continuous-Flow Analysis for Determination of Nitrate Using Hydrazine-Copper Method in Plan = Hydrazine-Copper 방법을 이용한 연속흐름제어장치를 통한 식물체의 nitrate 분석

다국어 초록 (Multilingual Abstract)

This study is to describe continuous-flow analysis (CFA) for the determination of nitrate using hydrazine-copper in plant material and to test precision of this method compared with that of methods, which are RQflex method and salicylic acid method. Samples were leaves of watermelon, cucumber, melon and tomato. Nitrate values measured by the RQflex method were greater than those measured by CFA or salicylic acid method. The correlation of nitrate values between those measured by CFA and salicylic acid method was $R^2=0.9671$, and those measured by CFA between those measured by RQflex method was $R^2=0.9739$. Recovery rate of nitrate added to tissue extract by CFA method was $99.7{\pm}0.25%$.
