The identification of those variables that have a major effect on plutonium peroxide precipitation was done in two ways. The first way used t-test values associated with each variable. The comparative magnitude of these values indicates the relative importance of the variable. The second way involved a subjective evaluation of the relative importance of each of the variables based on a visual comparison of the graphs constructed from the experimental data (Figures 1 through 12 plus a couple of dozen other comparable graphs that could not be included in this paper because of space limitations). The results of the subjective evaluation indicate that only the nitric acid concentration and the rate of hydrogen peroxide addition have a major effect on the relative filtration time. The other four variables influence the... 

USE For determination of free HC1 in gastric juice spot test identification of peroxidized fats pH indicator (red 2.9, yellow 4,0). 

OTHER COMMENTS used as a pH indicator used in the spot test identification for peroxidized fats used in dyes, soap, wax products, and polystyrene used in organic research... 

Identification The compound is suiq)ended in hot concentrated sulfuric acid, and diluted with water. Undissolved solid is filtered off, and a few drops of hydrogm peroxide test solution are added to the clear filtrate. The pcKitive identification consists of an orange-red color which develops immediately. 

Silicones are produced in the form of resins, oils, greases, and also as rubberlike elastic products. These materials also appear as processing aids in the manufacturing of plastics, as impregnation compounds, coatings, separating materials, mold releases, etc. They can be identified because they contain the element silicon. To test for silicon, mix approximately 30 mg of the sample with 100 mg sodium carbonate and 10 mg sodium peroxide. Heat this in a platinum or nickel crucible over a flame. Dissolve the melt in a few drops of water, boil it, and then add dilute nitric acid until the solution is neutral or slightly acidic. The identification of silicon then follows in the usual way with the addition of a few drops of ammonium molybdate. (See Chapter 4.)... 

The first concern in identification of an unknown waste is safety. The laboratory worka- who carries out the procedures should be familiar with the characteristics of the waste and any necessary precautions. Because the hazards of the materials being tested are unknown, it is imperative that proper personal protection and safety devices such as fume hoods and shields be employed. Older samples can be particularly dangerous because they may have changed in composition, for example, through the formation of peroxides. (See Chapter 3, section 3.D.3.2, and Chapter 5, section 5.G.3, for more information on peroxides.)... 

Procedure. A drop of the reagent solution and a drop of water are placed on a spot plate in an adjacent depression a drop of the reagent solution and a drop of the test solution are used for comparison. A more or less intense blue color or precipitate is formed, depending on the hydrogen peroxide content. Limit of Identification 0.08 y hydrogen peroxide Limit of Dilution 1 600,000...
