THMs in disinfection by products are especially important because of their potential carcinogenity. In this work two different liquid-phase microextraction methods namely US EPA 551 microextraction method and German DIN 38407 standard method were compared for the determination of trihalomethanes (THMs) including chloroform (CHCl3), bromodichloromethane (CHBrCl2), dibromochloromethane (CHBr2Cl) and bromoform (CHBr3) in water samples was developed, with analysis by gas chromatographyelectron capture detection (GC-EC...

In this study, natural radioactivity removal methods have been compared for present drinking water supplies (privately owned wells or small water works) which have radioactivity values higher than determined standards (WHO \& EPA standards). There are several methods known to remove radioactivity from water such as aeration to remove “Rn222”, adsorption by granular activated carbon (GAC) to remove “Uranium”, ion exchange methods (IX) to remove “Ra266 and Ra288”, reverse osmosis (RO) to remove “Gross ...
