On the determination and distribution of hydroxylated aromatic compounds in estuarine waters

Abstract

A modified methodology to determine the hydroxylated aromatic compounds in aquatic waters and sediments has been developed. Interference in seawater samples were overcome by addition of citrate solution permitting the blue colour development on reduction of tungsto‐ and molybdo‐ phosphoric acids by the aromatic hydroxylated groups present in lignins and tannins. The above procedure was adopted to study the fate of tannin and lignin like substances (TALLS) in tropical estuarine and coastal waters and sediments receiving pulp‐paper effluents.

Key Words:

• Hydroxylated aromatic compounds
• estuarine waters
