Sunlight mediated reactions

The chemistry of chlorine discussed in this section includes hydrolysis and optimum pH range of chlorination, expression of chlorine disinfectant concentration, reaction mediated by sunlight, reactions with inorganics, reactions with ammonia, reactions with organic nitrogen, breakpoint reaction, reactions with phenols, formation of trihalomethanes, acid generation, and available chlorine. [Pg.756]

Reaction mediated by sunlight. Aqueous chlorine is not stable in the presence of sunlight. Sunlight contains ultraviolet light. This radiation provides the energy that drives the chemical reaction for breaking up the molecule of hypochlorous acid. The water molecule breaks up, first releasing electrons that are then needed to reduce the chlorine atom in HOCl to chloride. The overall reaction is as follows ... [Pg.760]

In aerated waters, which are essentially all sunlight illuminated waters, the reactive species present in the highest concentration is O2 [1], with a concentration at saturation of about 2.5 x 10mol 1 Hence, O2 is the dominant scavenger of the photogenerated reactive species. The overall photoprocesses will thus be mediated by reactions with DOM itself and the reactions of the three primary photo transients with ground-state oxygen, Oj [13] ... [Pg.15]
