Abstract
The sorption of copper by suspended particulate matter from river wate r was investigated as a function of pH and solids concentration. Water was collected from the Delaware River and particulate matter was conc entrated using Tangential-Flow Filtration (TFF). The adsorption of cop per increased with increasing pH until pH 9.0. A decrease in copper ad sorption was found for higher pH values. The adsorption of copper was greater for the samples with added copper than for the suspension for which no metal was added. An increase of copper adsorption proportiona l to particulate matter concentration was also observed. At both pH 6. 0 and 7.0, there was a decrease in the adsorption of copper with incre asing copper concentration.
