Description
Dihaloacetonitriles (DHANs) are shown to be produced
by the chlorination of natural water, thus joining the
ranks of the trihalomethanes (THMs) likewise produced by
chlorination. Certain amino acids such as aspartic acid,
tryptophan, and tyrosine are implicated as precursor substances
for the DHANs and also to some extent for the THMs.
The degradation of DHANs by hydrolysis and by thiosulfate
was studied. Various methods of analysis are evaluated with
respect to their ability to determine DHANs and THMs. The
dilemma faced by water plants in dealing with the dual
problem of DHANs and THMs is discussed. The role of hydrolysis
in the formation of THMs has also been evaluated.
