Abstract Aldehydes and ketones compounds before and after electrostatic fume purifiers were sampled using 2,4-dinitrophenylhydrazine (DNPH) silica tube at nine restaurants, and then high performance liquid chromatography (HPLC) was used for quantitative measurement. Total concentrations of aldehydes and ketones compounds in the exhaust from nine restaurants ranged from 419.5 to 3372μg/m3 before the purifiers, while they varied from 415.8 to 2934μg/m3 after the purifiers. the concentrations of reference volume condition corresponded to 783.4~3761 and 541.7~2997μg/m3, respectively. It suggested that their concentrations were related to different cooking processes, the number of working stoves and the exhaust air volume. The concentration of C1~C3compounds accounted for more than 66% of the total detected carbonyl groups. formaldehyde was the highest detected compound, followed by acetaldehyde. The content of C4~C8compounds was relatively low. The average purification efficiency of electrostatic fume purifier on aldehydes and ketones compounds was 31.82%, with the highest efficiency reached to 69.14%. Formaldehyde has the highest purification efficiency with an average of 35.21% and a maximum of 80.10%. The composite electrostatic fume purifier can achieve a better purification effect than the normal electrostatic fume purifier.
