摘要：Usually the concentrartion of metals in river water in general, except the extremely polluted river water, is in the ppb level and, therefore, determination by the ordinary method, such as the direct atomic absorption spectrophotometry, on sampled water results often in "not detected" in expression. An apparatus consisting of a filter, a constant flow pump, a cation-exchange resin column, and an integrated volume counter, was used for collection of metal ions in natural water. Sample water (about 100-200 liters) was passed through the apparatus at a flow rate of about 10 ml/min. Metal ions adsorbed on the resin were eluted with 6 N HCl solution and determined by atomic absorption spectrophotometry. This method has permitted the determination of a trace amount of metals in public water.
