Chemical Pretreatment of Nuclear Waste for Disposal

Chemical pretreatment of nuclear wastes refers back to the series of separations strategies used to partition such wastes right into a small quantity of high-level waste for deep geologic disposal and a bigger quantity of low-level waste for disposal in a near-surface facility. Pretreatment of nuclear wastes now kept at numerous U.

1 - 1 - 1 - 1 - 1 - 1 Functionalization of diazotized aldehyde |3-naphthylhydrazone aminopolystyrene with nitroform- Several batches of each type of aminopolystyrene functionalized with nitroform­ aldehyde P-naphthylhydrazone were prepared and characterized by infrared and ultra­ violet spectroscopy. ; ACS Symposium Series; American Chemical Society: Washington, DC, 2000. 32 diarylnitroformazans (17,18). The best results in the synthesis of unsupported diarylnitroformazans were obtained when the reaction mixture was buffered to p H about 4 to 5 as noted above.

Ideally, if a mathematical function can be established between the structural parameter of the sensor and the chemical or odorous molecule, the odor detectability or intensity properties can be estimated. When coupled with gas chromatography, the quantitative relationship between a sensor response and partition coefficient (K) can then be related to odor polarity, chain length or molecular weight. If the value of K of an organic molecule having chain lengths C , Q , and C i is known, it would be possible to estimate the strength of the odor by interpolation of partition coefficient versus the number of carbon atoms.

Oxidation with dilute hydrogen peroxide produced an almost black solid. The infrared spectra exhibited changes in die 1000-1340 c m region with domination of a band around 1152 c m . Presently available methods do not allow a quantitative comparison of supported diarylthiocarbazones obtained by different oxidation methods . Therefore these products were tested in reactions with heavy metals ( P b and H g ) . 005 M Pb -* and H g . There were changes in the infrared spectra of such samples treated with heavy metals similar to those discussed above.
