Extensive use of zeolite nanoparticles in many areas, including medicine, has led to the concern about an impact and possible risk of their use for human health and the environment.In our studies, we investigated an uptake, retention, and cytotoxicity of nanozeolite A (BaA) functionalized with aminopropyl or poly(ethylene glycol) (PEG) of different chain lengths using human cervical carcinoma c...

The 223Ra, 224Ra, and 225Ra radioisotopes exhibit very attractive nuclear properties for application in radionuclide therapy. Unfortunately the lack of appropriate bifunctional ligand for radium is the reason why these radionuclides have not found application in receptor-targeted therapy. In the present work, the potential usefulness of the NaA nanozeolite as a carrier for radium radionuclides ...

For both period and cumulative growth performance data, there were trends for increased feed intake and increased feed to gain ratios associated with increasing concentrations of dietary clinoptilolite. If, however, efficiency was expressed as daily intake of megacalories of metabolizable energy, there were no treatment effects. This lack of treatment response is illustrated by overall cumulati...

Batch tests and column tests were performed to determine the design factors for permeable reactive barriers (PRBs) against the contaminated groundwater by ammonium and heavy metals. Clinoptilolite, one of the natural zeolites having excellent cation exchange capacity (CEC), was chosen as the reactive material. In the batch tests, the reactivity of clinoptilolite to ammonium, lead, and copper wa...

Clinoptilolite is a natural mineral with exceptional physical characteristics resulting from its special crystal structure, mainstreamed into a large zeolite group called heulandites. An overall view of the research related to the synthesis, modification and application of synthetic clinoptilolite is presented. A single phase of clinoptilolite can be hydrothermally synthesized for 1-10 days in ...

The object of present study was to examine the adsorption potential of nanozeolite clinoptilolite (CP) for the removal of malachite green (MG) from aqueous phase in a batch equilibrium system. SEM, EDX, XRF, XRD and FT-IR techniques of characterization of zeolite were applied. The effects of initial pH solution, adsorbent dose, temperature, contact time and initial MG concentration on adsorptio...

Improper use of urea may cause environmental pollution through NH3 volatilization and NO3 (-) leaching from urea. Clinoptilolite zeolite and compost could be used to control N loss from urea by controlling NH4 (+) and NO3 (-) release from urea. Soil incubation and leaching experiments were conducted to determine the effects of clinoptilolite zeolite and compost on controlling NH4 (+) and NO3 (-...

The aim of this study was to carry out kinetic, thermodynamic, and surface characterization of the sorption of Cs+ ions on natural minerals of kaolinite and clinoptilolite. The results showed that sorption followed pseudo-second-order kinetics. The activation energies were 9.5 and 13.9 kJ/mol for Cs+ sorption on kaolinite and clinoptilolite, respectively. Experiments performed at four different...

Clinoptilolite is a nontoxic natural zeolite with properties of an ion-exchanger and adsorbent. Earlier studies showed that clinoptilolite could be an adjuvant in cancer therapy. The aim of this study was to define effects of clinoptilolite in cell media on cell viability and activity of key proteins regulating cell survival, cell division and stress response. The number of viable cells, DNA sy...

Zeolites are crystalline hydrated tektoalumosilicates consisting of a three-dimensional framework of SiO4 4and AlO4 5tetrahedra linked through shared oxygen atoms. The heulandite group of zeolites including clinoptilolite are the most abundant zeolites in nature 1, 2 . Clinoptilolite is used in a wide range of industrial and agricultural applications, particularly in animal nutrition. Dietary i...
