An important role in the retention/adsorption mechanisms are both interactions between liquid phase components and adsorbent surface, effects connected with fluid flow through bed. Unfortunately, retention mechanism most adsorption systems (e.g. chromatography) is unknown further investigations needed. In this work, sorption of caffeine phenol as test substances various has been analyzed. Inves...

Abstract The adsorption of chloroxylenol and chlorophene on halloysite-carbon composites was investigated in batch flow systems. synthesis through two different methods performed with microcrystalline cellulose as carbon precursor. obtained were characterized by SEM/EDS analysis, the low-temperature nitrogen adsorption/desorption methods, infrared spectrometry (FT-IR). analysis FT-IR spectra co...

In this paper, biochar was modified by cetyltrimethylammonium bromide (CTAB) and KOH solution, it characterized TGA, FT-IR, XRD, BET, SEM. Then, the (MB) used to immobilize free laccase (FL) adsorption method prepare (MBL). The degradation performance for 2,4-DCP via MB, FL, MBL were studied. results showed that under optimal conditions, rate of MB on up 42.5%, capacity 85.13 mg/g, proved confo...

The simulated moving bed (SMB) process has been extensively used in industrial separations for binary and pseudo-binary separations. In pseudo-binary mixtures because the desired component is the most or least retained, the other components do not have to be separated. The UOP Parex process for p-xylene purification is an example. When non-target components have similar adsorption behaviors, th...

Understanding strength and nature of noncovalent binding to surfaces imposes significant challenge both for computations and experiments. We explored the adsorption of five small nonpolar organic molecules (acetone, acetonitrile, dichloromethane, ethanol, ethyl acetate) to fluorographene and fluorographite using inverse gas chromatography and theoretical calculations, providing new insights int...

The competitive adsorption of human serum albumin (HSA), human immuno-gamma-globulin (HIgG) and human fibrinogen (HFb) onto polystyrene (PS) at 20 degrees C and a pH of 7.35 (phosphate-buffered saline) was studied. Protein adsorption was studied using enzyme immunoassay. The results obtained with the immunoassay were compared with those obtained using radiolabelled proteins. Recent studies reve...

The aim of this work was to produce chitosanase by fermenting from squid pen, and recover the fermented squid pen for dye removal by adsorption. One chitosanase induced from squid pen powder (SPP)-containing medium by Bacillus cereus TKU034 was purified in high purification fold (441) and high yield of activity recovery (51%) by ammonium sulfate precipitation and combined column chromatography....

Proteins derived from plant resources such as oilseed meals, canola and sunflower, are considered a viable alternative to animal proteins for food consumption. This work presents rational methodology, using high throughput experimentation (HTE), the separation of cruciferin napin, two major meal, by chromatography. Eight different mixed mode ion exchange resins were evaluated at conditions with...

PURPOSE Tear lipocalin (Tlc) is a major lipid binding protein in tears and is thought to have an important role in stabilizing the Meibomian lipid layer by transferring lipids to it from the aqueous layer or ocular surface, or by adsorbing to it directly. These possible roles have been investigated in vitro using human Tlc. METHODS Tlc was purified from human tears by size exclusion chromatog...
