Heterogeneous uptake of gaseous hydrogen peroxide by Gobi and Saharan dust aerosols: a potential missing sink for H2O2 in the troposphere
gaseous hydrogen peroxide Gobi and Saharan dust aerosols H2O2 the troposphere
2010/8/16
The first direct laboratory measurements of gaseous hydrogen peroxide uptake by authentic Gobi and Saharan dust aerosol particles as a function of relative humidity (RH) have been carried out in an en...
Technical Note: Measuring condensation sink and ion sink of atmospheric aerosols with the electrical low pressure impactor (ELPI)
condensation sink ion sink atmospheric aerosols ELPI
2010/2/21
We investigate the suitability of ELPI for condensation sink and ion sink measurements. The aim is to find the simple calibration factors by which the measured ELPI current can be converted to condens...
Oxidation of SO2 by H2O2 on ice surfaces at 228 K: a sink for SO2 in ice clouds
SO H2O2 ice surfaces SO2 ice clouds
2009/3/12
The heterogeneous reaction SO2 + H2O2 H2SO4 on ice at 228 K has been studied in a low temperature coated-wall flow tube. With H2O2 in excess of SO2, the loss of SO2 on an ice surface is time depende...
Laboratory study on heterogeneous decomposition of methyl chloroform on various standard aluminosilica clay minerals as a potential tropospheric sink
heterogeneous decomposition methyl chloroform aluminosilica clay minerals potential tropospheric sink
2009/3/11
Methyl chloroform (1,1,1-trichloroethane, CH3CCl3) was found to decompose heterogeneously on seven types of standard clay minerals (23 materials) in dry air at 313 K in the laboratory. All reactions p...
