PILS-ion chromatography-voltammetry combined with simultaneous measurement of anions, cations and heavy metals in the air.rar
The air is converted into liquid by the action of the vacuum pump in the air sample liquefier. The air sample liquefier can continuously provide sample flow for detection by ion chromatography and voltammetry. This paper describes the method of online analysis of aerosol in air by using an air sample liquefaction instrument, voltammetry, and ion chromatography. Among them, the voltammetry can analyze the content of heavy metals such as Zn, Cd, Pb, Cu in the air, and the ion chromatograph can analyze Cl-, NO2-, NO3-, SO42-, Li +, Na +, NH4 +, K + in the air , Ca2 +, Mg2 + and other anions and cations.
