chromium (vi) adsorption behavior and capacity by surface modified nanozeolite a has been investigated. surface modification was performed and the morphology of modified and unmodified nanozeolite was studied using scanning electron microscope (sem) and transmission electron microscope (tem). adsorption isotherms were studied under different conditions (ph, adsorbent dose, adsorbate concentrati...

Adsorption characteristics of potentially toxic metals in single- and multi-metal forms onto ferronickel slag were evaluated. Competitive sorption of metals by ferronickel slag has never been reported previously. The maximum adsorption capacities of toxic metals on ferronickel were in the order of Cd (10.2 mg g(-1)) > Cu (8.4 mg g(-1)) > Zn (4.4 mg g(-1)) in the single-metal adsorption isotherm...

Interaction between various species in natural systems may affect the adsorption of these species and thereby their mobility and bioavailability. Recently an ion adsorption model has been developed, based on the surface structure of metal (hydr)oxides and the structure of surface complexes identified by spectroscopy. This model has been applied to the adsorption of phosphate and weak organic ac...

The mobility of As in soils depends on several factors including redox potential, soil mineralogy, pH, and the presence of other oxyanions that compete with As for soil retention sites. We investigated the effects of pH and competing anions on the adsorption of arsenate [As(V)] on a-FeOOH (goethite) and y-AI(OHb (gibbsite). Batch equilibrium As(V) adsorption experiments were conducted with P an...

The interactions between lysozyme-imprinted hydrogel and their template protein were studied using adsorption measurements, competitive adsorption experiments, and isothermal titration calorimetry (ITC). The results were compared to the interactions between the imprinted polymer and a reference protein, cytochrome c. Experimental adsorption isotherms and competitive adsorption studies detected ...

A commercial multiwall carbon nanotube and its carboxylated derivate (CNTC and COOHC, respectively) was used after purification to study the competitive adsorption of phenol (P) and m-chlorophenol (CP) from 0.1 M aqueous NaCl solutions without external pH control. The adsorption takes place practically exclusively on the external surface of the nanotubes. The uptake of P is suppressed in compar...

Boron adsorption on the clay minerals, kaolinite and montmorillonite, and two arid zone soils was investigated as a function of solution pH (3-12) and presence of competing anions (nitrate, sulfate, molybdate, and phosphate) after 2 h of reaction time. Boron adsorption on all materials increased from pH 3 to 8, exhibited a peak at pH 8 to 10, and decreased from pH 10 to 12. Boron adsorption was...
