Precipitation Processes

561
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Atomic Absorption Spectroscopy: Atomization Methods

618
Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the...

Area of Science:

  • Atmospheric Science
  • Cloud Physics
  • Aerosol Science

Background:

  • The Aerosol Interaction and Dynamics in the Atmosphere (AIDA) chamber is a crucial facility for studying atmospheric processes.
  • Understanding aerosol interactions is vital for accurate climate modeling and weather prediction.

Purpose of the Study:

  • To introduce and validate the AIDA mini (AIDAm) chamber for automated, long-term ice nucleation measurements.
  • To investigate the influence of chemical surface coating on the ice nucleation properties of mineral dust aerosols.

Main Methods:

  • Utilized the AIDA mini (AIDAm) chamber, a 20 L extension of the AIDA facility, for automated measurements.
  • Validated AIDAm's temperature control for homogeneous freezing of water and immersion freezing by dust aerosols.
  • Conducted experiments at cirrus cloud temperatures to differentiate ice formation mechanisms on mineral dust and sulfuric acid particles.
  • Monitored ice nucleation activity over 7 hours during slow sulfuric acid coating of dust particles with 6-minute resolution.

Main Results:

  • AIDAm demonstrated accurate ice nucleation temperature control and the ability to distinguish between homogeneous and heterogeneous freezing.
  • Experiments showed that sulfuric acid coating significantly suppressed heterogeneous ice formation on dust particles.
  • A gradual increase in homogeneous freezing was observed as dust particles became coated.

Conclusions:

  • The AIDAm chamber is a valuable tool for sensitive, long-term studies of aerosol ice nucleation.
  • Chemical processing, such as surface coating, can substantially alter the ice nucleation behavior of aerosols.
  • Findings contribute to a better understanding of cloud formation processes and aerosol-cloud interactions in the atmosphere.
