Nitrate-sensitive PVC matrix membrane electrodes produced in the German Democratic Republic are suited for determining nitrates in feeds and plants if the different causative parameters are taken into account. A rational determining method is presented. Comparisons with the o-cresol method showed statistically confirmed agreement.
德意志民主共和国生产的对硝酸盐敏感的聚氯乙烯基质膜电极，若考虑到不同的影响参数，适用于测定饲料和植物中的硝酸盐。本文提出了一种合理的测定方法。与邻甲酚法的比较显示出经统计学证实的一致性。
