✦ Synopsis

Ahstraet Gas chromatography with flame lonlzation detectlon (GC-FID) was used to determme the volatile fatty acids m landfill leachates Dlstdlatlon was mvestlgated for sample pretreatment A sample was dlstdled with sulphunc acid to Increase the recovery of fatty acids and remove the longer resident speaes and morgamc salts The hght-end dlstlllate was discarded prior to the chromatographlc step Concentration ratloos of volatde fatty acids m the dlstdlate to sample solution were studied Ghost peaks on the gas chromatogram were ehnunated by high-temperature condltlomng The results mdlcated that the method 1s apphcable to fatty acid determmatlons, mth very good correlation coefficients for the cahbratlon graphs The apphcatlon of the dlstdlatlon-GC-FID method IS Illustrated for leachate samples from the Talchung samtaIy landfill
