Recent Advances in Chemistry and Technology of Fats and Oils

In view that we produced fat and Oils: Chemistry and know-how in 1980, the rage we expected to up-date the classical texts of oils and fat has manifested itself. Bailey's well-known textbook has been thoroughly revised and a moment version of Bernardini's paintings has been produced. the current textual content is an try to offer a few perception into the present state-of-the-art.

Example text

Technetium, promethium, and all elements heavier than bismuth are radioactive, and no stable isotopes usable as carriers exist. In these cases a chemically analogous stable element can be used as a carrier. For example, Ba is generally used as a carrier for 226 Ra. Both are alkaline earth metals and barium is the next heaviest. Both form a divalent ion in solutions and behave chemically, more or less, in the same way. This is an example of the use of a nonisotopic carrier. In the same way trivalent lanthanides can be used as the carrier of trivalent actinides, for example Eu3 þ can be used as a carrier for 241 Am since they are chemically very much alike: americium also forms Am3 þ ion in solution.

The reason for these oxo forms is that the ionic potential of pentavalent metal ions is very high, and the positive charge of the metal attracts oxygen atoms of water molecules so strongly that all hydrogen atoms are liberated and covalent bonds are formed between the metal and the oxygen. This process takes place with nonmetals also. Elements of smaller size appear as oxoanions – among the elements having important radionuclides iodine as iodate (IO3À) and niobium as niobate (NbO3À). Ion sizes of the actinides, in turn, are so large that, in pentavalent form, they bind the oxygen atoms of only two water molecules and form ‘yl’ ions: uranyl UO2 þ , neptunyl NpO2 þ , and plutonyl PuO2 þ .

Finally, the digital pulse goes into a multichannel analyzer which sorts the pulses into different channels based on their pulse height. In this way, an energy spectrum is obtained. The most challenging tasks in LSC are sample preparation and efficiency calibration. The former is discussed in Chapter 5. Efficiency calibration is needed to take into account the quenching that affects the counting efficiency. Quenching is a decrease in the efficiency of energy transfer from the beta particles, for example, to the scintillator, and a decrease in light photon intensity before they reach the PMTs.
