Abstract
Ion exchange resin-loaded paper disks containing a highly selective ion exchange resin serve as an excellent medium for separating and collecting trace quantities of elements in an optimum form for x-ray spectrographic and neutron activation determination. A new collection procedure provides a simple means for preconcentrating the trace elements from large samples. A radioactive tracer added to the original sample is used as the collection monitor. Use of a cyclotron-produced radiotracer permits the application of this procedure to neutron activation determination. The determination of gold in the ppm range by x-ray spectrography and in the ppb range by neutron activation are given as examples.
