Sorption of Aqueous Organics by Aquifer Material: Correlation of Batch Sorption Parameters with Octanol-Water Partition Coefficient

Abstract

AbstractA study of sorption of aqueous organics by aquifer materials was undertaken with an objective to correlate sorption parameters with the octanol-water partition coefficient (KOW) of aqueous samples. In the first phase, synthetic samples were equilibrated with the aquifer material collected from the river bank filtration (RBF) site located on the bank of the river Alaknanda at Srinagar, Uttarakhand, India. In the second phase, water from the river Hindon at Barnawa, Uttar Pradesh, India, was stirred with the Srinagar aquifer material, and a sample of water from the Elbe River was mixed with the aquifer material from the RBF site in Torgau, Germany. The fraction of organic carbon content (foc) in the aquifer material from Srinagar and Torgau was 0.018 and 0.0027 mg/mg, respectively. The hydrophilic and hydrophobic nature of the synthetic samples and the water samples from the rivers Hindon and Elbe were determined by measuring KOW and specific ultraviolet absorbance (SUVA). Empirical correlations be...
