UV Recovery of Organic Pollution Parameters

The common part of UV and classical parameters (TOC, COD and BOD) is the biodegradable fraction of organic matter. The most comparable parameter is certainly the TOC, which also includes carbohydrates (sugars) and aliphatic (saturated) hydrocarbons not absorbed in the UV region. Some specific compounds as nitrates are associated with the UV response. 

More precisely, the main organic compound families are more or less recovered by the aggregate parameters and by UV spectrophotometry (Table 7). Additional comments can be made concerning organic compounds containing hetero-atoms (N or S). They are at 

Y 90-100% of conversion or high absorption or absorption after photo-oxidation. P partially converted or some absorbing compounds.
