Abstract

Изобретение относится к способу измерения NОх в жидкости, в котором выделяют жидкую пробу, регулируют рН и/или ионную силу указанной пробы во время t0, регистрируют значение mV, присутствующее в указанной пробе, с помощью избирательного зонда NOх в заранее определенное время t1, регистрируют еще одно значение mV2, присутствующее в указанной пробе, по истечении еще одного заранее определенного времени t2, определяют концентрации NOх в указанной пробе в каждом заранее определенном интервале времени t1 и t2, определяют изменения NOх, и определяют концентрацию NOх. Достигается упрощение способа и расширение возможностей его применения. 2 з.п.ф-лы, 3 ил.
