New solid phase extraction methods have been developed to allow determination of residual normal paraffin hydrocarbon (NPH) and tri-n-butyl phosphate (TBP) in aqueous radioactive streams from the Purex process. The techniques concentrate organic materials and separate them from radioactive species for analysis by gas chromatography. TBP and NPH have good radiolytic and chemical stability and have low aqueous solubility. However, they can contaminate aqueous streams and cause processing difficulties. Knowledge of the concentration of organic materials in aqueous waste is useful in assessing impact on pollution control equipment. The storage quality of diluent-washed aqueous plutonium product solution can be determined by a gas chromatographic analysis for residual TBP. 4 refs., 1 fig., 7 tabs.
