Abstract
Resin-loaded papers composed of approximately 50 percent cellulose and 50 percent ion-exchange or chelating resin provide an ideal matrix for many x-ray spectrographic analyses. Standards are prepared by multiple filtration of solutions of known composition through the paper to achieve quantitative collection or by the use of a radio-tracer as a monitor for nonquantitative collection. Solutions prepared from unknown samples are processed in the same manner as the standards. Advantages of the resin-loaded papers are as follows: reduction of interelement effects because standards and unknowns are present in a similar low x-ray absorbing matrix; physical parameters such as metallurgical history, grain size, and surface preparation are eliminated; and sampling errors are significantly reduced and sensitivity greatly increased by concentrating trace elements separated from large samples. Application of these papers to a variety of metallurgical, geological, and water samples will be summarized. The possible use of resin-loaded papers as standards for air pollution monitoring will be examined.
