Organic analysis and analytical methods development: FY 1995 progress report

PDF Version Also Available for Download.

Description

This report describes the status of organic analyses and developing analytical methods to account for the organic components in Hanford waste tanks, with particular emphasis on tanks assigned to the Flammable Gas Watch List. The methods that have been developed are illustrated by their application to samples obtained from Tank 241-SY-103 (Tank 103-SY). The analytical data are to serve as an example of the status of methods development and application. Samples of the convective and nonconvective layers from Tank 103-SY were analyzed for total organic carbon (TOC). The TOC value obtained for the nonconvective layer using the hot persulfate method ... continued below

Description

This report describes the status of organic analyses and developing analytical methods to account for the organic components in Hanford waste tanks, with particular emphasis on tanks assigned to the Flammable Gas Watch List. The methods that have been developed are illustrated by their application to samples obtained from Tank 241-SY-103 (Tank 103-SY). The analytical data are to serve as an example of the status of methods development and application. Samples of the convective and nonconvective layers from Tank 103-SY were analyzed for total organic carbon (TOC). The TOC value obtained for the nonconvective layer using the hot persulfate method was 10,500 {mu}g C/g. The TOC value obtained from samples of Tank 101-SY was 11,000 {mu}g C/g. The average value for the TOC of the convective layer was 6400 {mu}g C/g. Chelator and chelator fragments in Tank 103-SY samples were identified using derivatization. gas chromatography/mass spectrometry (GC/MS). Organic components were quantified using GC/flame ionization detection. Major components in both the convective and nonconvective-layer samples include ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), succinic acid, nitrosoiminodiacetic acid (NIDA), citric acid, and ethylenediaminetriacetic acid (ED3A). Preliminary results also indicate the presence of C16 and C18 carboxylic acids in the nonconvective-layer sample. Oxalic acid was one of the major components in the nonconvective layer as determined by derivatization GC/flame ionization detection.
