Usually constipation delays transit time, increasing the adsorption of toxins generated from misdigestion of food; by coating and locking up significant portions of colon it also reduces the adsorption of certain minerals and electrolytes.
They make the colon's wall rigid and interfere with peristalsis thus leading to further problems with constipation, and interfere with adsorption of nutrients.
Its basic nature seems to be well established by its behavior with phosphotungstic acid and its ready adsorption by carbons activated to take up basic substances.
The author ban recently been able to obtain a concentrate vitamine from an extract of alfalfa or autolysed yeast with the aid of a carbon specially activated by McKee of Columbia University for the adsorption of basic substance.
How far the penetration has proceeded is easily determined by utilising the different adsorption of coal-tar dyes by untanned and tanned pelt (see p.
In the preceding pages emphasis has been laid upon the importance of the adsorption law, the lyotrope series, and the valency rule.
In the first pits entered by the goods there is rapid adsorption in spite of the low concentration and small astringency, and the great aim is to obtain evenness of action and a good level colour.
Here again dilution of the sol reduces the adsorption and correspondingly reduces, to some extent, the difficulty.
Thus sumach-tanned goatskins are wet back from the crust and "retanned" in sumach before dyeing, to coat the fibres with a fresh and more adsorbent gel and so ensure the even and thorough adsorption of the dyestuff.
The fibres of the pelt are dried in a separate condition, but the adsorption is easily reversible and the pelts may be "depickled" by weak alkalies and afterwards given an ordinary vegetable tannage.
In addition to the adsorption phenomena described, there are in vegetable tannage secondary changes which are slow and "irreversible.
Further, decolorization by adsorption probably also involves the removal of the last traces of emulsified grease.
These pits contain the strongest liquors of the yard, and their principal function is to complete the tannage and give weight and firmness by the adsorption of bloom, reds, etc.
As gelatin is primarily slightly positive, it is probable that the values of a and of n for hydrion adsorption will be relatively slightly greater.
In bating and puering the essential change is that before the process the swelling is due chiefly to adsorption of hydroxyl ions, whereas afterwards it is due chiefly to a composite lyotrope influence.
Sand and burned clay only show faint adsorption phenomena; felspar shows them to a slight and almost negligible extent and most of the other non-plastic ingredients of clays are non-adsorptive.
Ashley (11) has endeavoured to measure the plasticity of clays by determining their adsorption capacity for various aniline dyes, but his untimely decease prevented the investigation being completed.
There is reason to suppose that the relation between adsorption and plasticity is extremely close in many clays and that the former may, to an important extent, be used as a measure of the latter.
Selective adsorption being an important characteristic of colloidal substances, the possession of this power by plastic clays supports the claim that plasticity is due, at least in part, to the presence of colloids.
To some extent the power of adsorption of salts and colouring matters appears to be connected with the plasticity (p.
Since substances which are in the colloidal form have very large relative surface areas, it follows that the opportunity for surface adsorption on colloidal materials is very great.
In this, adsorptiondiffers from chemical action, as the latter is proportional to the concentration of the reacting material which is present in the solution.
An increase of ten times in the concentration of the dissolved material results in only four times as much adsorption by the colloidal substance which may be introduced into the two solutions.
Hence, the surface adsorptionof reacting bodies by a colloidal catalyst may have a very important influence in decreasing the time required to bring the reacting molecules into intimate contact, and so increasing the velocity of the reaction.
Again, colloidal adsorption effects often lead to the so-called "capillary segregation" of added staining materials.
Here, we deal with adsorption and other colloidal phenomena, rather than with ordinary stoichiometric combinations.
Adsorption out of different liquids, by the same adsorbing body, is different in amount.
It is, however, brilliantly red in color, and crystallizes in a different form and has a different adsorptionspectrum from carotin.
Certain characteristics of adsorption phenomena are of interest and importance from both the physiological and the industrial point of view.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "adsorption" in a variety of sentences. We hope that you will now be able to make sentences using this word.
