Popis: Abstract The Bureau of Indian Standard (BIS, New Delhi) has framed a set of standards for drinking water description (IS 10500:1991-http://www.indiawaterportal.org), which has specifications drawn up in 1983 with the most current amendment (July, 2010), and the US Environmental Protection Agency (USEPA 2003) has also developed policy for different drinking water disinfection by-products (DBPs). This study examined the quality of metropolitan drinking water by monitoring the physicochemical parameters, and DBPs study such as the effects of halide ions, natural organic matter, and drinking water characterization were investigated. The sampled water had halo phenols DBPs as a result of disinfection, during chlorination. The water was alkaline in nature, and the water temperature varied from 33 to 37 °C. The major ions, namely bromate, iodate, chlorite, chromate, sulfate and phosphate, have been investigated in the municipality drinking water, Tiruchirappalli and Srirangam in Tamil Nadu, India. Here, three solvents such as hexane, petroleum ether and pentane were used for the liquid–liquid extraction of target compounds. The gas chromatographs equipped with capillary columns (DB-WAX) were employed for the determination of DBPs and 2-bromo-4-chlorophenol was predominantly identified.
