lüll Ion chromatography applications in the determination of HF, HCl, NOx, SOx on stationary emissions Giuriati C; Cristofori MC; Gorni A; Abballe FAnn Ist Super Sanita 2003[]; 39 (2): 223-8In this work, specific topics will be covered in order to verify an effective, routine application of ion chromatography as a suitable and approved technique for emission monitoring in the determination of HF, HCl, NOx and SOx on stationary emission. A review of the analytical methods as proposed by recent updates in Italian environmental law and the problems encountered in the application of this method, such us the interference due to high level of carbonate, high hydroxides concentration particularly on SOx and NOx absorbing solution, are considered in the present work. The sample treatments before the IC analysis, this to reduce the matrix interference due to the strong basic solutions used to monitor different stationary emissions, are also examined. Some modifications in sampling are explored to find more suitable conditions for the IC analysis.|*Chromatography, High Pressure Liquid/instrumentation/methods[MESH]|*Chromatography, Ion Exchange/instrumentation/methods[MESH]|Absorption[MESH]|Air Pollutants/*analysis[MESH]|Environmental Monitoring/instrumentation/legislation & jurisprudence/*methods/standards[MESH]|Hydrochloric Acid/analysis[MESH]|Hydrofluoric Acid/analysis[MESH]|Hydrogen Peroxide[MESH]|Hydrogen-Ion Concentration[MESH]|Nitrogen Oxides/analysis[MESH]|Potassium Permanganate[MESH]|Sodium Hydroxide[MESH]|Solutions[MESH]|Sulfur Oxides/analysis[MESH] |
