In this study, Acrylamide (AAm)/Acrylic Acid (AAc) hydrogels have been synthesized from AAm and AAc monomers in three different composition (AAm/AAc mole ratios: 1/2,1/1,2/1). Poly(AAm/AAc) hydrogels were used to adsorb a water-soluble monovalent cationic dye such as Safranine T (ST) and the adsorption behavior was studied by spectrophotometer.
The adsorption behavior for hydrogen of Pt-Sn catalyst prepared by conventional impregnation method is similar to that of Pt-Al2O3, the same continuous desorption spectra were observed in the range of 0-500℃.
Preliminary thermal treatment in vacuum is found to markedly affect the adsorption behavior of polyhydroxyaluminum montmorillonite with respect to toluene.
Opposite picture of the adsorption behavior of studied acids in n-hexane corresponds to negative volume effects of the dissolution of the acids in this solvent.
The adsorption behavior of zirconium molybdate toward Cs(I) (134Cs), Co(II) (60Co), Zn(II) (65Zn), and Eu(III) (152, 154Eu) ions in aqueous solutions was studied in relation to the contact time, composition of aqueous solutions, and temperature.
The adsorption behavior of water-soluble polyelectrolytes on mineral and synthetic adsorbents was analyzed.
The adsorption behavior of the nitrate anion is quantitatively described by the APK model, whereas the Frumkin model is preferable in the case of butanol.
