Validation of a solid phase extraction technique for the determination of halogenated acetic acids in drinking water
Haloacetic acids (HAAs) are one of the most common disinfection by-products formed during chlorination of drinking water. An analytical method involving solid phase extraction (SPE) followed by gas-chromatograph mass-spectrometry (GC-MS) was developed and optimized using experimental design to deter...

Haloacetic acids (HAAs) are one of the most common disinfection by-products formed during chlorination of drinking water.

Under optimized conditions, average recoveries for nine HAAs spiked in drinking water samples range from 69.2% to 108.2 %.
