Neutralizing removes the large amount of hexavalent chromium from the surface of the part. Hexavalent chromium shortens the life of the catalyst, and trace amounts completely inhibit electroless nickel deposition. The neutralizer is usually a mildly acidic or basic reducing agent, but other types of neutralizers are available, especially for substrates that are difficult to plate. The neutralizer may also contain surfactants (qv) or other compounds that increase catalyst absorption absorption promoters are often needed for non-ABS plastics.

Absorption. Absorption, the attenuation of a beam through a transparent medium, can be characterized by an absorption coefficient. For thin films, such as those of optical oxides, absorption is very small and can usually be ignored. In metallic or semiconductor coatings however, absorption is a major factor. 

PERCUTANEOUS ABSORPTION Absorption via the skin, e.g. due to local contamination or a splash of chemical. 

The location of the tip of the feeding tube is important when considering medication administration down a feeding tube. This is particularly true if the medication acts locally in the GI tract itself. For example, sucralfate and antacids act locally in the stomach. Therefore, administration of these medications through a duodenal or jejunal tube is not logical. Likewise, for medications such as itraconazole that require acid for best absorption, administration directly into the duodenum or jejunum would be expected to result in suboptimal absorption. Absorption of drugs when administered directly into the small bowel, especially the jejunum, rather than into the stomach is another area where more research would be useful. 

Self-Absorption—Absorption of radiation (emitted by radioactive atoms) by the material in which the atoms are located in particular, the absorption of radiation within a sample being assayed. 

Absorption. Absorption was discussed in Chapter 10. If possible, a component that already exists in the flowsheet should be used as a solvent. Introducing an extraneous component into the flowsheet introduces additional complexity and the possibility of increased environmental and safety problems later in the design. 

Figure 1 Overview of transport models for predicting oral drug absorption. Absorption models are classified into three categories based on their dependence on the spatial and temporal variables. These three categories are quasi-equilibrium, steady-state, and dynamic models. 

Concepts Interaction of radiation with matter Light and matter interact by scatter and absorption. Absorption only occurs when the colour of the radiation is the same as an energy separation within the molecule, but scatter occurs at all wavelengths... 

The type and amount of carotenoids consumed affects carotenoid absorption. Absorption of (3-carotene from large doses is independent of dose size (Tanumihardjo 2002). The response of (3-carotene in serum and milk was similar in women supplemented with 60 or 210 mg of (3-carotene (Canfield and others 1997). In contrast, small carotenoid doses are more efficiently absorbed than large ones (West and Castenmiller 1998 Furusho and others 2000 Tanumihardjo 2002).

Absorption. Absorption of cyanide across the gastrointestinal mucosa depends on the pH of the gut and the pKa and lipid solubility of the particular cyanide compound. Hydrogen cyanide is a weak acid with a pKa of 9.2 at 25 °C. The acidic environment in the stomach favors the non-ionized form of hydrogen cyanide and facilitates absorption. Information regarding the rapid lethal effects following oral intake of cyanide in humans (Gosselin et al. 1976) indicates that cyanide is rapidly absorbed from the gastrointestinal tract. 

Absorption - Absorption of miglitol is saturable at high doses a dose of 25 mg is completely absorbed, whereas a dose of 100 mg is only 50% to 70% absorbed. Peak concentrations are reached in 2 to 3 hours.
