almcm-41 was applied for adsorption of methylene blue (mb) and auramine (au) in single and binary component systems. in the single component systems, almcm-41 represents higher adsorption capacity for mb than au with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚c for mb and au, respectively. in the binary component system, mb and au exhibit competitive adsorption onto...

adsorption of bovine serum albumin (bsa) onto calcium hydroxyl apatite (ha), ca10po4(oh)2, has been studied by ultra violet (uv) spectroscopy. the adsorption isotherms of bsa onto the ha surface at 291.7 k and 303.2 k were satisfactorily presented by langmuir equation and the evaluated parameters are reported. the specific surface area of ha has been measured by the bet method. the obtained val...

background & aims of the study: p-chloronitrobenzene is a benzoic compound that widely used in many chemical industrials. p-chloronitrobenzene may be absorbed through the skin and is suspected to causing cancer. so, developing an easy method to remove of it from the environment is necessary. equilibrium isotherms and adsorption kinetics of p-chloronitrobenzene onto modified silk waste were stud...

This paper describes the performance of Granular Activated Carbon (GAC) to adsorb and separate glucose and maltose solutes from the industrial effluents by adsorption process. In this study, the capability of Granular Activated Carbon (GAC) to adsorb glucose and maltose were experimentally examined. Commercial GAC (mesh 12-20), supplied by Sigma Aldrich company in...

The Dubinin-Radushkevitch (D-R) equation, which was originally proposed as an empirical adaptation ~d'the Polanyi adsorption potential theory, has been the fundamental equation to quantitatively describe the adsorption td gases and vapors by microporous sorbents. The equation, based on the postulate that the mechanism for adsorption in micropores is that of pore-filling rather than layer-by-lay...

Adsorption process is an important technique in separation processes, which is used in heavy metals removal from aqueous solution. Orange peel has been investigated for the adsorption of uranium ions from aqueous solution. The parameters of pH, contact time, initial uranium ion concentration, temperature and adsorbent dose have been investigated in batch experiments. The adsorption kinetics wer...

the adsorption study was conducted on three japanese soils with different soil properties to characterize the adsorption pattern of arsenic (as). double tube method was used to find out the effect of soil moisture levels on as adsorption. for this study, besides double tube method, conventional batch method also was used. the as adsorption showed two phase kinetics. an initial and rapid adsorpt...

Zirconium based metal organic frameworks (Zr-MOFs) have become popular in engineering studies due to their high mechanical stability, thermostability and chemical stability. In our work, by using a theoretical kinetic adsorption isotherm, we can exert MOFs to an acid dye adsorption process, experimentally exploring the adsorption of MOFs, their external behavior and internal mechanism. The resu...

Surface plasmon resonance (SPR) imaging is a surface-sensitive spectroscopic technique for measuring interactions between unlabeled biological molecules with arrays of surface-bound species. In this paper, SPR imaging is used to quantitatively detect the hybridization adsorption of short (18-base) unlabeled DNA oligonucleotides at low concentration, as well as, for the first time, the hybridiza...
