Area of Science:

  • Environmental Science
  • Analytical Chemistry
  • Occupational Health

Background:

  • Ketones are common industrial solvents and potential workplace hazards.
  • Accurate monitoring of airborne ketone concentrations is crucial for occupational safety.
  • Existing air sampling methods may have limitations in efficiency or scope.

Purpose of the Study:

  • To develop and evaluate a novel solid sorbent passive air sampler for detecting various ketones.
  • To determine the sampling rates of the developed passive sampler for several OSHA-regulated ketones.
  • To assess the sampler's potential for monitoring aldehydes as well.

Main Methods:

  • A passive air sampler was designed with a silicone membrane and a Tenax TA sorbent coated with O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride.

  • Controlled exposure experiments were conducted using a dynamic air dilution system to generate known ketone concentrations.
  • Ketone derivatives were desorbed with hexane and analyzed using gas chromatography with mass spectrometric or electron capture detection.

    • Main Results:

    • The passive sampler demonstrated measurable sampling rates for multiple ketones, including cyclohexanone, diethyl ketone, and methyl ethyl ketone.
    • Sampling rates at 25°C varied among the tested ketones, ranging from 3.43 to 6.48 mL/min.
    • Preliminary findings suggest the sampler's capability to collect sterically unhindered ketones and potentially aldehydes.

    Conclusions:

    • The developed solid sorbent passive air sampler shows promise for monitoring workplace exposure to various ketones.
    • The sampler's performance characteristics, including sampling rates, were quantified for several key compounds.
    • Further research may expand its application to include aldehyde monitoring.
