Materials and methods
- Study type:
- direct photolysis
- Principles of method if other than guideline:
- Direct photolysis in water was studied in distilled water and in the presence of humic substances respectively. A very diluted aqueous nitrobenzene solution was exposed to irradiation. The influence of humic substances on photoreactions was determined by comparing results in humus-containing water with those in distilled water.
