O SO2 fixado no filtro impregnado com solução de Na2CO3 1,0 x 10-2 mol L-1 foi extraído com uso de banho de ultra-som e solução de H2O2 durante 15 min, e determinado como SO42- por cromatografia iônica. O amostrador apresentou bom desempenho, exceto sob condições de estagnação total do ar (0 m s-1), para períodos de exposição muito curtos (0,5 h), em atmosfera contendo O3 > 150 mg m-3 e compostos reduzidos de enxofre em altas concentrações. A umidade relativa do ar (20 - 80%) e exposição à concentração zero não afetaram o desempenho. Mostrou estabilidade por um mês quando estocado a 4 ºC ou por uma semana à temperatura ambiente (»25 ºC). Sua precisão variou entre 3,5 e 23% dependendo da concentração de SO2 e a exatidão entre 91 e 100%.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-01-09T17:42:35Z No. of bitstreams: 1 a08v16n1.pdf: 235250 bytes, checksum: 4ef2eed174eb3a9508c6d470c43d881e (MD5)Made available in DSpace on 2012-01-09T17:42:35Z (GMT).
