【摘要】 本文以玻璃电极作指示电气,用直接电位法测定NH₄⁺离子与甲醛反应所定量地释放出的H⁺离子,间接测定氨氮含量,对高含量的氨氮,还可用电位滴定法测定。更多还原

【Abstract】 This paper uses the PH-glass electrode as a indicativeelectrode, that it suitable for the indirect determination of nitrogen in ammonium by the direct potentiometry determination ot H+ which is formed when N H4+ reacts with formaldehyde.High content of nitrogen in ammonium also can be determined by the. metnod of potentiometric titration.更多还原
