“…In Table 1, Langmuir sorption capacity of Cyanex 272@PSF capsules for Co(II) was compared with other adsorbents previously reported in the literature. Sorption capacity of Cyanex 272@PSF capsules (2.014 mg/g) is higher than that of silica gel modified with 4-phenylacetophynone 4-aminobenzoylhydrazone (1.060 mg/g) [50], kaolinite (0.919 mg/g) [51] and silica gel modified with benzophenone 4-aminobenzoylhydrazone (0.117 mg/g) [52].…”

“…Figures 5(g)-(h) illustrate the adsorption isotherms of both the [PPim][PF 6 ] templated and non-templated TiO 2 nano-particles toward cyt-c at pH 9.0. The adsorption capacity of both types of nano-TiO 2 particles for a protein species could be derived by the Langmuir isotherm equation [26].…”

Porous nano-titanium dioxide (TiO(2)) particles with anatase framework were prepared by using an effective template of hydrophobic ionic liquid, i.e., N, N-bis [2-methylbutyl] imidazolium hexafluorophosphate ([PPim][PF(6)]). The nano-TiO(2) particles were characterized with TEM and BET, resulting in the distribution of the pore diameters centering at 7.3 nm and 26.2 nm, attributed to the template effect of the ionic liquid and the aggregation of the TiO(2) particles, respectively. A much improved surface area of 68.31 m(2) g(-1) and a pore volume of 0.2814 cm(3) g(-1) were obtained with respect to 15.16 m(2) g(-1) and 0.0402 cm(3) g(-1) achieved by the non-templated nano-TiO(2) counterpart. The porous nano-TiO(2) particles were used as adsorbent for selective adsorption and isolation of cytochrome c (cyt-c) at certain conditions. An adsorption efficiency of 87% was achieved for 150 microg ml(-1) cyt-c in 1.0 ml of sample solution at pH 9.0 by using 2.0 mg of the nano-TiO(2) particles, in comparison to 30% obtained by the non-templated nano-TiO(2). In addition, an adsorption capacity of 112.6 microg mg(-1) was derived for the porous nano-TiO(2) with respect to 25.1 microg mg(-1) for the normal ones. The absorbed cyt-c could be readily recovered by stripping with a 0.1 mol l(-1) Na(3)PO(4) solution, giving rise to a recovery of ca. 90%. The porous nano-TiO(2) particles have been used for the isolation of cyt-c from human whole blood, achieving satisfactory results by assay with SDS-PAGE.

“…These covalently bonded organic groups are highly stable and resistant to removal from the surface by organic solvents or water [16]. To this end, a great number of organic molecules were immobilized on silica gel surface, xylenol orange [17], 2-thiophenecarboxaldehyde [18], di( n -propyl)thiuram disulfide [19], 4-acylpyrazolone [20], aminothioamidoanthraquinone [21], 1,8-dihydroxyanthraquinone [22], murexide [23], oxime derivatives [24], resacetophenone [6], diphenyldiketone monothiosemicarbazone [25]. These systems can be operated indefinitely without loss of the expensive organic molecules.…”

Abstract:A new chelating matrix, SiNP, has been prepared by immobilizing 1.5-dimethyl-1H-pyrazole-3-carbaldehyde on silica gel modified with 3-aminopropyltrimethoxysilane. This new chelating material was well characterized by elemental analysis, FT-IR spectroscopy, cross polarization magic angle spinning solid state 13 C-NMR, nitrogen adsorption-desorption isotherm, BET surface area, BJH pore size, and scanning electron microscopy (SEM). The new product exhibits good chemical and thermal stability as determined by thermogravimetry curves (TGA). The new prepared material was used as an adsorbent for the solid-phase extraction (SPE) of Pb(II), Cd(II), Cu(II) and Zn(II) from aqueous solutions using a batch method, prior to their determination by flame OPEN ACCESSMolecules 2014, 19 248 atomic adsorption spectrometry. The adsorption capacity was investigated using kinetics and pH effects. Common coexisting ions did not interfere with separation and determination.
