摘要: Abstract An analytical method based on gas chromatography–mass spectrometry (GC–MS) has been developed to determine non-volatile fraction of disinfection by-products (DBP) in drinking water. Solid phase extraction (SPE) with tri-methyl-ammonium chlorine (TMA-Cl) cartridges is followed by derivatization desired analyte the eluted extract. The studied factors are elution volume, methy-tertiary-butyl ether (MTBE) volume and time. Experimental design was used investigate subsequently optimize derivatizing agent (10% acidic methanol), MTBE time for haloacetic acids (HAAs) water sample. Regression models desirability functions were applied find an experimental setup acquiring highest global yield HAAs. only statistically significant from this study. In final optimized conditions, procedure SPE–GC–...
