Formation of chloroform by aqueous chlorination of organic compounds

Thirty organic compounds were selected to investigate their chloroform formation characteristics during chlorination with sodium hypochlorite at pH-values 7.0 and 8.0. These experiments were conducted under conditions similar to those applied on the chlorination of raw water. The results indicated that the chloroform concentrations occurred by the all tested compounds was in the ppm range. The maximum levels of chloroform (11 – 13 mg/l) were determined during the reaction of resorcinol and phloroglucinol at pH-value 8.0.
