The formation potential of total trihalomethanes and total organic halides (TOX) on aromatic hydrocarbons such as benzoic acid, salicylic acid, m-hydroxybenzoic acid, p-hydroxybenzoic acid, catechol, resorcinol, hydroquinone, reacted with chlorine were investigated.
TOX were formed in less than 2 hours after reaction with chlorine, but trihalomethane formation by hydrolysis of trihalomethane intermediates took long terms (3days) to become constant values.
There was a linear relationship between chlorine demand and TOX formation potential to aromatic hydrocarbon reacted with chlorine.
The patterns of TOX formation by chlorination were able to classify at least 3 groups.
The formation rate of trihalomethanes to TOX was 0.3-16.6%, but formation potential of trihalomethanes and TOX was not correlate.
