The acidity probes discussed above are the most commonly used. However, the use of many different probes has been reported in the literature. This list includes nitriles, alkanes, amines, water, di-hydrogen, deuterium, isotopically labeled molecules, benzene, etc. Probe molecules can also be used to measure basicity on zeohtes. In this case, weakly acidic molecules such as CO2, pyrrole, acetic acid and halogenated light paraffins have been used. Space does not permit discussion of these in any detail, but information about these probes and their applications can be found in the following references [87, 127-130]. 

The UV visible measurements are performed using a commercial HR 2000 high-resolution fibre optic Ocean Optics spectrophotometer equipped with a halogen light source HL2000. The detector is a linear silicon CCD array. The spectral resolution measured with a Hg-Ar calibration lamp is better than 0.2 nm.

Environmentally conscious to a fault, Earth s dining room is a study in modern design. Scrap wood from a recently demolished building was used for their hardwood floors, and recycled medals used to make tiny tables. Halogen lighting, potted fig trees and bowls of goldfish complete the scene. 

The range of applications is somewhat restricted, since the cost of most polymeric adsorbents is typically about ten times more than that of other common adsorbents. In some instances, polymeric materials are the only choice. In other cases, they compensate for the cost differential by yielding much better performance, especially for high value-added uses. Current applications include recovery and purification of antibiotics and vitamins, decolorization, decaffeination, hemop-erfusion, separation of halogenated light orgaifics from water, and treatment of certain industrial wastes such as aqueous phenolics and VOC recovery from off-gases. 

Superluminescent LEDs (SLEDs) are LEDs pumped at high current so that stimulated emission occurs. These miniature light sources are approximately 1000 times brighter than a tungsten-halogen light bulb. 

Figure 11 Oxidation of As(IIt) to As(V) in irradiated ferrioxalate solutions containing 1 mM oxalate, and 18 pM Fe(III) and As(lll). Solutions were irradiated using a halogen light source (97 pE cm hr between 300 and 500 nm) at pH values of 3, 5, and 7. The rapid oxidation of As(III), especially at pH 3-5, was shown to be due to the production of OH" free-radical species during irradiation of ferrioxalate (From Ref. 76.)...

Noncontact-type heating allows heat transfer by noncontacting methods to fluids such as radiative and ultrasonic heating. Infrared temperature control [4] is a noncontact heating technique, which uses the infrared excitation of a vibration band of water combined with a high-power halogen light bulb and an optical Alter (Fig. 2).
