A procedure for determining cation‐exchange capacity of river suspended sediment is described. Water samples for suspended sediment analyses were obtained from the Spoon River in Illinois. The procedure involves two substitution steps to convert all exchange sites to potassium, five washing steps to remove the excess cation, and two replacement steps using barium. The replaced potassium was determined with an atomic absorption spectrophotometer. Reproducibility is excellent; and the procedure is applicable to a wide range of suspended sediment concentration.
