| Abstract | ||
| High performance liquid chromatography (HPLC/UV) and gas chromatography methods to determination of formaldehyde in bottled drinking water were used. Here, GC method was used to determine quantitatively formaldehyde using TCD (thermal conductivity detector) followed by analysis by HPLC / UV , while sensitive UV detection can be non-specific, and is subject to many interferences , and the analysis time can be long , as well as, some laboratories do not have equipments or experts for HPLC analysis . Therefore, gas chromatography method provides an alternative to HPLC, eliminating the need for a solvent mobile phase. Resolution and sensitivity are good for aldehydes evaluated. Results of this study indicate that the detection for formaldehyde was good even of low concentration in GC. Ten bottled drinking water samples collected from various markets were analyzed. The results were below the guide – line for drinking water quality by WHO (900 ppb). | ||
