Form of application

Ion exchange (IX) is a very useful technique for the concentration, the purification and the separation of chemically similar metallic elements present in an aqueous solution. In its most popular form of application, the metal-bearing aqueous solution is passed through a bed of solid organic resin in a particulate form wherein the sorption of the metal ions on the resin takes place by ion-exchange reactions. The pregnant resin is washed free of the entrapped feed solution and then brought into contact with an eluant of suitable composition and volume so that the resin releases the metal ions back to the eluant. The ratio of the volume of the feed and that of the eluant determines the extent of concentration that can be achieved. Purification and separation are achievable if the resin is selective or specific with respect to the metal ions of interest in comparison to impurity ions. [Pg.500]

Nevertheless this does not involve, imply, or express any guarantee or responsibility on the part of the publishers in respect of any dosage instructions and forms of application stated in the book. Every user is requested to examine carefully the manufacturers leaflets accompanying each drug and to check, if necessary in consultation with a physician or specialist, whether the dosage schedules mentioned therein or the contraindications stated by the manufacturers differ from the statements made in the present book. Such examination is particularly important with drugs that are either rarely used or have been newly released on the market. Every dosage schedule or every form of application used is entirely at the user s own risk and responsibility. The authors and publishers request every user to report to the publishers any discrepancies or inaccuracies noticed. [Pg.388]

Bithionol is a chlorinated bisphenol with antihehninthic properties. It is active against most trematodes and has been recommended as preferable to praziquantel in fascioliasis and paragonimiasis, proving both effective and well tolerated. Bithionol also has antibacterial properties and was for this reason included for a time in cosmetic formulations. However, when given topically it caused photosensitivity reactions, and this form of application has been abandoned. [Pg.527]

Variation Type 1 requires notification of BODMDR with supporting evidence special application forms of application are being prepared. Time frame from the application and obtaining an annex of a variation to the previously issued Registration Certificate is 2-3 months. Variation Type 11 in most cases requires a new application and as such may take a long period of time. [Pg.483]

A special form of application results when gases are absorbed by the molten mass (enter into solution) or are stirred into the melt (mechanical distribution). The material expands and foams after exiting from the nozzle. The densities are reduced by about 100% compared to the compact adhesives. This type of adhesive application... [Pg.249]

It is clear that a consolidation treatment for wall paintings suitable for all situations cannot be expected in the near future. The treatment will be determined by the amount of consolidation necessary, the material and the form of application possible at the specific site. It is also necessary to take climate into... [Pg.259]

Orally, both antibiotics are used for the treatment of intestinal infections due to susceptible organisms and, in combination with other drugs, for bowel sterilization prior to surgery. Owing to poor absorption from the gastro-intestinal tract, this form of application has rarely led to side-effects. Both are used either alone or in combination with other antibiotics in a variety of ointments and solutions for topical application on infected surface lesions of skin and mucuous membranes " . Allergic reactions have rarely been observed. [Pg.32]

The application of 2,3-dimercaptopro-pane-1-sulfonic acid (DMPS) increases the renal excretion of mercury. This increase depends heavily on the DMPS dosage, the form of application (oral or intravenous), and the duration of urine collection (spontaneous urine sample, collection of urine for 4 or 24 h) (Schiele et al. 1989). After oral administration of 300 mg DMPS, the following upper limits of the reference... [Pg.960]

Flow. In industry, adhesives are frequently applied to the wood by means of roll or spray applicators. Often the result is, initially, discrete strips or droplets of glue on the wood. These discrete areas of glue should flow or merge to form a continuous film. Some forms of application (e.g., curtain coating and hand brushing) produce a continuous film from the outset. Flow, as a separate step, would not be involved in this case. [Pg.376]

Polyolefins and Polyamides, Modern hot-melt adhesive compounds are commonly based on polymers of the polyolefin or polyamide type. The polyolefin-based ones are usually modified with other natural and synthetic polymer resins and waxes. The melt temperatures of hot melts vary rather widely. Some begin to melt just above 100°C, whereas others may require temperatures in the range of 200°C to melt. The high-temperature ones might very well damage the artifacts being bonded. Hot melts may be of considerable interest in conservation gluing, but additional research is needed on the most appropriate formulations and forms of application. [Pg.387]

The application enabling level, which utilizes the functions contained within the system enabling level, is composed of three domain sub-integration platforms (SIPs) MIS SIP, CAD/CAM/CAPP SIP, and shop-floor control SIP. Each SIP is designed according to the requirements of a domain apphcation and provides functions for applications in the form of Application Dependent API (AD API). The AD API functions are designed specifically to enable the quick and easy development of... [Pg.517]

Conductors. Materials with free electrons, such as metals, are materials that reflect electromagnetic waves just as light is reflected by a mirror. These materials are used to contain and direct electromagnetic waves in the form of applicators and waveguides. [Pg.288]

To understand the behavior of the fluidized bed, one can determine the average residence time or the residence time distribution (RTD) from the tracer technique. For instance, RTD in fluidized bed dryer is usually carried out by means of the stimulus-response technique, in which an impulse of solids marked with some appropriate tracer is fed to the dryer and its time of elution and concentration measured at the exit of the dryer. The material of the tracer has to be such that it can be detected and does not react with the substrate material, and its form of application and response are well known (Levenspiel, 1972). [Pg.585]

These types of adhesives can be broadly classified by their physical form of application and/or the way they are activated to form a bond with the material to which they are applied, for example, as emulsion polymers, solution polymers, hot melts and reactive polymers (see Adhesive classification). Each of these will now be considered in turn. [Pg.39]

The law on the composition of chemicals (Chemikaliengesetz) [7-48] discusses limiting values as a function of the forms of application listed in Table 7.25. [Pg.300]
