Abstract

In the present study the activities of uranium were measured in water column, suspended particulate matter (SPM) and surface sediment along the Sungai Selangor, which is from river, estuary and near-shore. During high tide, the activities of uranium were found highly in the particulate phase (234U = 350.93±11.69 mBq g-1 and 238U = 243.55±9.33 mBq g-1), where the activity of uranium in particulate phases is slightly correlated with the amount of suspended particulate matters. A strong adsorption of uranium occurred onto the suspended particles matter was showed by the distribution coefficient (Kd) values as 2366 x 10-3 L g-1 and 1363 x 10-3 L g-1 for 234U and 238U, respectively.
