[ClickPress, Wed May 15 2019] Adsorption apheresis devices is used for separation of blood component from blood, so that each component can be used for medical treatment.
Poly(ionic liquid)s have attracted much attention in the field of adsorption and separation, because they not only inherit the physical and chemical properties such as adjustability, molecular designability and excellent thermal stability of ionic liquids, but also overcome the high viscosity, recycling difficulty and the consequent toxic and corrosive risk of ionic liquids [14, 15].
Poly(ionic liquid)s also draw great attention in the field of heavy metal ions adsorption. Due to the "designability" of ionic liquid monomers, hydrophobic anions can be induced into the molecular chain of Poly(ionic liquid)s, and the resultant hydrophobic polymer can be easily isolated in aqueous after adsorbing heavy metal ions.
Batch adsorption studies were carried out and the effect of experimental parameters Such as pH, initial dye concentration, temperature, adsorbent dose and contact time, on the adsorption of MB was studied.
The main conventional methods used to decontaminate waters are based on the membrane separation techniques [5-7], the reverse osmosis [8], the biological processing [9] and the adsorption [10].
The literature also suggest a mechanism for which the adsorption of transitional metals on these kind of surfaces, through the formation of a covalent bond between the metal ion and the oxidic surface, called chemisorption, according to equation (2) where M could be any transitional metal.
Such kind of reaction modifies the surface charge through more positive values, which allows anion adsorption, and produces acidification through the formation of H3O+ ion.

Different methods such as physical method (like reverse osmosis), chemical method (like ion-exchange) and adsorption could be applied for the removal of dyes but it was found that biosorption process is cheap, efficient, simple, eco-friendly, effective and economic for the removal of MB dye [4].
The adsorption characteristics of tea catechins onto defatted rice bran were determined over a range of concentrations of 0.5 grams per liter to 2.5 grams per liter, and at temperatures of 10 C, 25 C and 45 C.
The present study carried out experiments to test the change of coal resistivity during adsorption and desorption of gas, with the aim of specifying a new method of predicting coal gas content.
Many experimental studies have been reported on the adsorption of surfactant onto colloidal particles of metal oxides [2, 3, 5-9].
However, C[H.sub.4] adsorption on the as-prepared CNTs is generally a weak physisorption process, which means that the uptake capacity can be low.
Similarly, thermodynamic studies are of prime importance to predict whether the adsorption is spontaneous or not.
