Desenvolvimento De Amostrador Passivo Sensível Para Monitoramento De Poluição Atmosférica Por Dióxido De Nitrogênio

Abstract: publicado na web em 12/09/2017 DEVELOPMENT OF SENSITIVE PASSIVE SAMPLER FOR NITROGEN DIOXIDE AIR POLLUTION MONITORING. A passive sampler constructed with a new type of material and used for measurement of ambient nitrogen dioxide is presented. The sampler was constructed with parts of two 50 mL conical centrifuge tubes. The procedure is based on NO 2 uptaken on cellulose filter impregnated with triethanolamine. After sampling, the analyte is solubilized and placed to react with Griess-Saltzman solution. The ab… Show more

“…Among the alternatives for its construction, we can mention passive samplers constructed using sections of 38-mm polycarbonate filter holders (Millipore), as described in a previous article published (Garcia et al 2014). But for the experiments presented in this work, we chose to use the design of passive samplers proposed by Souza et al (2017). The passive sampler was designed and built with commercial material that is easy to purchase, reducing analysis costs.…”

“…A curva analítica e sua equação são apresentadas na Figura 2. quantidade de gás coletada no período (n x ). Considerou C 0,x igual a zero, pois segundoSouza et al (2017), em uma superfície absorvente ideal todo o NO 2 é coletado e a sua concentração na interface da superfície absorvente é nula. O valor do coeficiente de difusão molecular foi obtido por Massman (1998) como igual a 0,1361 cm 2 s -.…”
