AbstractSpecific ultraviolet absorbance (SUVA) is the ratio of ultraviolet absorbance (UVA) to dissolved organic carbon (DOC) or UVA per unit of DOC. The octanol water partition coefficient (KOW) is the ratio of the concentration of the organic compound in octanol to that in water. Both of these parameters depend on the nature of the organic substance or the functional groups present in the organic compound. Two very different compounds may have the same KOW or SUVA, the ratio of KOW to SUVA of these will be different. Therefore, these two parameters for a particular category or nature of compounds are likely to be correlated. The present project aims at preliminary investigations to establish the correlation between KOW and SUVA for four categories of organic compounds. Keeping this objective in view, 41 synthetic samples containing a single organic compound of known concentration were prepared and analyzed for SUVA and KOW. UVA was measured at 254 nm and at maximum absorption (λmax). The KOW, SUVA254, a...
