The widespread application of Ukrainian natural zeolites in sorption and catalysis is limited by the shortcomings their porous structure. Chemical modification permits significant changes properties. purpose this work was to obtain silver-containing clinoptilolite type with improved characteristics acid treatment study antibacterial Mild dealumination rock carried out using ethylenediaminetetra...

We show that simulation of gas adsorption in nanoporous sorbents may be highly sensitive to accurate crystallographic coordinates, even for frameworks anticipated to have low flexibility.

The review is devoted to the work, which were performed at V.I. Vernadskii Institute of General and Inorganic Chemistry NAS Ukraine according direction development sorption naterials wide functional purpose. All sorbents can be used in separation processes: due their coarse dispersion mechanical strength, they as fillers for columns.The early works amorphous hydrophosphates double hyd­rated oxi...

Excessive concentrations of heavy metals in food we eat are among the current issues safety. This becomes especially evident if consider highly toxic elements such as copper, lead and cadmium. With regard to foregoing, it would be helpful get information about use novel sorbents livestock farming their effects on distribution animal bodies. The drug study is based natural mineral raw materials ...

These article summaries the results of studying sorption equilibrium ions close to their concentration in liquid industrial waste. For experimental research, solutions with Со2+ and Cd2+ range 1·10-3–1·10-4 N have been used. concentrations match ion con¬cen¬tration waste mentioned. In experiments, Na+- modified forms natural sorbents based on clinoptilolite from Aydag deposit bentonite Dash-Sal...

BACKGROUND Continuous dialysis could provide benefit by constant removal of potassium and phosphate. This study investigates the suitability of specific potassium and phosphate sorbents for incorporation in an extracorporeal device by capacity and regenerability testing. METHODS Capacity testing was performed in uraemic plasma. Regenerability was tested for potassium sorbents, with adsorption...

Solid oxides have been extensively investigated as possible high-temperature CO 2 sorbents by a number of research groups. We summarised the different strategies to develop synthetic solid oxide sorbents.

Natural Jordanian sorbent (consisting of primary minerals, i.e., quartz and aluminosilicates and secondary minerals, i.e., calcite and dolomite) was shown to be effective for removing Zn(II), Pb(II) and Co(II) from aqueous solution. The major mineral constitutions of the sorbent are calcite and quartz. Dolomite was present as minor mineral and palygorskite was present as trace mineral. The sorb...

The sorption capacity of modified activated carbon is investigated; the possibility creating a sorbent for iron (II, III) in water bodies with purified yield up to 0.01 mg/l shown. A sulfogroup was used as modifier and complexing agent. To date, thousands sorbents are produced various matrix materials, functional groupings, ways fixing them, containers, mechanical properties, granulation other ...

In this work, sorbents based on natural zeolite (Z) and chamotte clay (ChC) treated with NaCl HNO3 solutions were obtained to extract Na+ K+ ions from saline water. The physicochemical characteristics of the studied by SEM, EDAX, BET methods. It was found that successive treatment has a positive effect sorption properties materials. maximum increase in specific surface area 4.5 m2/g 39.3 is obs...
