Abstract
Sorption characteristics are reported for sediments from the west coast of India, where annual mudbank phenomena occur. Experimental studies were performed on a combination involving water and sediments from the mudbank region at different phosphate concentrations. Synthetic seawater as well as kaolin were also incorporated in these studies to understand the sorption characteristics. Field and laboratory studies were conducted under varying ionic concentrations to elucidate information on the phosphate desorption features. A biphasic or two‐slope sorption pattern helped to describe the kinetics of phosphate‐phosphorus mechanism in the high productive coastal waters.
