  Soil properties play a significant role in phosphorus (P) sorption. Information about P sorption is limited in Hamadan soils. The objectives of this research were to study the P sorption in twelve soils of Hamadan, assess the capability of different kinetics equations describing P sorption and correlate the P sorption characteristics with the soil properties. The soils were fertilized with 20...

Development of bio-based sorbents (i.e., chitosan moieties) at nanoscale size for the removal metal contaminants is main target this research. Grafting with thiazole heterocyclic derivative gives fast kinetics sorption, highly loading, and good recyclability mining leaching solution. Different analyses tools including (thermogravimetric analysis (TGA), scanning electron microscope energy disper...

Two porous supramolecular isomeric frameworks show unique sorption properties, one with temperature dependent stepwise and hysteretic selective sorption of CO(2) while the other one shows gas uptake capacity for CO(2), N(2), H(2) and CH(4) at low temperature and selective sorption of CO(2) over N(2) around room temperature.

Results: All materials tested demonstrated different degrees of sorption and solubility. The glass ionomer cement had the best value for sorption. The zinc oxide eugenol and eugenol free cements had lower water sorption than the zinc polycarboxylate and zinc phosphate cements were evaluated. Some materials retained water in their structure and thus compensated for any loss of mass due to dissol...

Poly urea-formaldehyde was synthesized simply and rapidly from urea and formaldehyde by condensation polymerization and studied for the sorption of trace acid blue from aqueous solution. The optimum pH value for sorption of the acid blue was 4. Experimental results showed that the sorption capacity of poly urea-formaldehyde for acid blue was determined. The synthetic polymer can be reused for 5...

Sorption of TCE to the caliche soil exhibited linear isotherm at the high TCE concentrations (Co=122-1300 mg L(-1)) but Freundlich isotherm at the low concentration range (1-122 mg L(-1)). Sorption strength of the carbonate fraction of the soil was about 100-fold lower than the sorption strength of soil organic matter (SOM) in the caliche soil, indicating weak affinity of TCE for the carbonate ...

Sorption of dissolved strontium on kaolinite, amorphous silica, and goethite was studied as a function of pH, aqueous strontium concentration, the presence or absence of atmospheric CO(2) or dissolved phosphate, and aging over a 57-day period. Selected sorption samples ([Sr(aq)](i) approximately 0.5-1x10(-3) m) were examined with synchrotron X-ray absorption spectroscopy (XAS) at low (13-23 K) ...

Batch sorption and column breakthrough studies were conducted to investigate the potential of layered double hydroxides (LDHs) to remove bacteriophage MS2 from contaminated waters. All four of the LDHs evaluated in this study had very high retention capacities for MS2. Sorption results showed that MS2 could be completely removed from 5.2 x 10(2) plaque-forming units (pfu)/mL solution by Mg-Al L...

The sorption of a protein pair on carboxylic cation exchangers with various contents of ionogenic groups is examined. The bi-Langmuir isotherm calculation is carried out from sorption data for single-component systems. It is shown that good agreement of calculated and experimental data is reached only when protein-sorbent interaction weakens because of implementation of the competitive sorption...

Organic micropollutants such as estrogens occur in water in increasing quantities from predominantly anthropogenic sources. In water such micropollutants partition not only to surfaces such as membrane polymers but also to any other natural or treatment related surfaces. Such interactions are often observed as sorption in treatment processes and this phenomenon is exploited in activated carbon ...
