由此可以认为,茶叶中影响N -亚硝化反应的主要成分为茶多酚,尤为茶儿茶素。
Thus, it might be concluded that blocking effect on NPRO formation was mainly due to tea polyphenolic compounds especially tea catechin in tea.
研究了在稀盐酸介质中微量亚硝酸根与二甲苯蓝FF发生的亚硝化反应,建立了测定微量亚硝酸根的新方法。
A new spectrophotometric method for the determination of trace nitrite is studied. The method is based on the nitrosation reaction of xylene cyanol FF with nitrite in diluted hydrochloric acid medium.
因此可以得出,好氧反应时间的控制在亚硝化阶段基本结束时是维持并稳定短程硝化的关键。
Therefore, it may be concluded that control of aerobic reaction ending at nitrosation stage is the key to the maintenance and stabilization of short-cut nitrification.
