FIELD: analytical methods. SUBSTANCE: method comprises isolation of liquid sample, adjusting pH and/or ionic force of sample for time NOx, registering mV value using t0-selective probe at predetermined time NOx, and registering one more value t1 after one more predetermined time mV2, after which concentration of t2 in sample is determined for each predetermined time interval NOx and t1, determining change in t2, and then concentration of NOx. EFFECT: simplified procedure and expanded application possibilities. 3 cl, 3 dwg |
