Effect of natural organic matter on monochloramine decomposition: pathway elucidation through the use of mass and redox balances
Article Abstract:
The presence of natural organic matter in drinking water reservoirs was found to be significant in monocholoramine decomposition, reducing the potency of the disinfection process. Natural organic matter was found to act as a reducing agent, where monochloramine is decomposed to yield higher concentrations of atmospheric nitrogen and NO3-. This decomposition process was validated both by mass and redox balance, where the oxidized product production equates with monochloramine loss.

Formation of carbon monoxide from the photodegradation of terrestrial dissolved organic carbon in natural waters
Article Abstract:
Carbon monoxide photochemical formation in water samples is discussed. Water samples were drived from wetlands, lakes, near coastal/shelf areas and in aqueous solutions of soil organic matter. Their optical properties and their carbon monoxide photoproduction rates were examined. The efficiencies for photochemical carbon monoxide production were subjected to model calculations. Similarities in carbon monoxide production were found among all the water samples examined.

Fractal nature of humic materials
Article Abstract:
The hypothesis that a humic material should be amenable to fractal geometry chracterization if its fundamental chemical characteristic is strongly disordered in nature was investigated. Test experiments involved the isolation and conversion of humic acid to acid form. Small angle x-ray scattering was used to examine the disorder of each humic material. Results indicate that the concepts of fractal geometry can be used to describe the nature of humic materials.
