Characterization of aerosol emissions from single bubble bursting

Charging of a single soap bubble

“…Bigger bubbles and those characterized by higher surface tension have higher rupture thickness. In [8] rupture thicknesses in the range of 0.13 to 0.98 µm were reported (for bubbles with radius in the range of 5 to 15 mm, and surface tensions in range from 34 to 50 mN/m).…”

“…In [9] maximum measured droplet diameter was 500 µm. In [8] the droplets of diameter from 0.5 to 10 μm were observed. The droplets distribution after bubble bursting is affected by bubble size, its lifetime, surface tension and used soap solution [6].…”

“…When a soap bubble bursts it produces droplets of various sizes [8,9]. In [9] maximum measured droplet diameter was 500 µm.…”

“…Assuming the radius of the bubble is 25 mm and the surface tension γ is 35 mN/m [8], the maximum charge of the bubble should be on the level of 55 nC. Dividing this by mass 4.5 mg [7] gives expected (Q/m) value around 12 mC/kg.…”

Caracterização microbiana da remoção e degradação de 4-Nonilfenol em Reator Anaeróbio de Leito Fluidificado em escala aumentada >i<

“…Apesar disto, o 4-NF possui log de Kow de 4,48, que indica baixa solubilidade em água e afinidade a matéria orgânica, conferindo baixa mobilidade do meio líquido para o gasoso (SOARES et al, 2008). O 4-NF pode atingir a atmosfera por meio de aerossóis gerados em ETE e em sistemas de lodos ativados devido a intensa aeração (KE et al, 2017). Uma vez que atinge a atmosfera, o 4-NF pode ser transportado para o ambiente terrestre por meio de deposição úmida (chuva, neve) (FRIES; PÜTTMANN, 2004).…”
