COMPARATIVE OF NATURAL ZEOLITE – CLINOPTILOLITE ELIMINATION OF METAL IONS/ESPECIALLY Cu (II) WITH D-PENICILLAMINE FROM BIOLOGICAL ENVIRONMENTS

Rudarsko-geološko-naftni Zbornik, 2021
Clinoptilolite is used as an adsorbent to remove heavy metal cations due to its function as a molecular sieve. This molecular sieve characteristic has made it possible to study the efficiency of clinoptilolite and D-Penicillamine in a comparative way in ...

Solid phase extractive preconcentration of silver from aqueous samples and antimicrobial properties of the clinoptilolite–Ag composite

Adsorption Science & Technology, 2017
Sorptive properties of the Transcarpathian clinoptilolite compared to Ag(I) were studied in a dynamic way. The sorptive capacity value of clinoptilolite under the optimal conditions is 11.7 mg of Ag per 1 g of zeolite.

Clinoptilolite supported feeding reduces excessive iron in thalassemia rat model created with iron loading

Medicine Science, 2021
There is no regulatory mechanism for the removal of iron that accumulates in the body. Thalassemia patients are most affected by iron overload. The method often used in the treatment of these patients is iron chelation therapy, which involves removing ...

The effects of clinoptilolite on piglet and heavy pig production

Italian Journal of Animal Science, 2010
To evaluate the effects of clinoptilolite on piglet and heavy pig production two separated trials have been performed. In the first trial 40 pigs of the initial body weight of 55 kg were used. Animals were homogeneously allocated to two groups: a control
