Inorganically modified diatomite as a potential prolonged-release drug carrier
(Elsevier, Amsterdam, 2014)
Inorganic modification of diatomite was performed with the precipitation product of partially neutralized aluminum sulfate solution at three different mass ratios. The starting and the modified diatomites were characterized ...
The efficiency of in vitro adsorption of mycotoxins by adsorbents of plant origin
(University of Novi Sad, Faculty of Technology, 2012)
The paper describes in vitro model for evaluation of ability of two adsorbents of plant origin, to adsorb different mycotoxins. Fresh harvested tissues of submerged aquatic plant Myriophyllum spicatum, obtained from Sava ...
Phytoremediation of uranium contaminated soils
(Nova Science Publishers, Inc., 2011)
Environmental uranium contamination based on human activity is a serious problem worldwide. Soil contaminated with uranium poses a long-term radiation hazard to human health through exposure via the food-chain and other ...
Removal of lead from aqueous solutions by using the natural and Fe(III)-modified zeolite
(Elsevier, Amsterdam, 2012)
In the present study, the sorption of lead by the natural and Fe(III)-modified zeolite (clinoptilolite) is described. The characterization of the natural zeolite-rich rock and the Fe(III)-modified form was performed by ...
Recycling of silver-plated brass for production of high purity copper and ultrafine silver powder for electric contacts
(Bulgarian Academy of Sciences, 2014)
The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining materials of higher value ...
Modified Natural Zeolites-Functional Characterization and Biomedical Application
(Wiley Blackwell, 2014)
Natural and synthetic zeolites have emerged as potential materials for biomedical application in recent years. Zeolites are hydrated microporous tektoaluminosilicates consisting of three-dimensional frameworks of SiO4 and ...
Potentiostatic oxidation of AgCu50 alloy in alkaline solution in the presence of chlorides
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
SEM and EDS analyses of AgCu50 alloy were performed after potentiostatic oxidation in an alkaline solution in the presence or absence of chloride ions. Oxidation in pure alkaline solution was favoured on the portion where ...
Linear Polarization Study of the Corrosion of Iron in the Presence of Thiobacillus ferrooxidans Bacteria
(Electrochemical Science Group, Beograd, 2012)
An electrochemical investigation was conducted to evaluate the corrosion behavior of iron in deionized water (DIW) and medium salt in the pH range of 1 to 4. The times of immersion of the electrode in solutions were changed ...
Ibuprofen sorption and release by modified natural zeolites as prospective drug carriers
(Mineralogical Soc, Twickenham, 2015)
The sorption of ibuprofen by modified natural zeolite composites at three concentration levels (10, 20 and 30 mmol/100 g) of cationic surfactants - benzalkonium chloride and cetylpyridinium chloride, in a buffer solution ...
Compost of Aquatic Weed Myriophyllum spicatum as Low-Cost Biosorbent for Selected Heavy Metal Ions
(Springer International Publishing Ag, Cham, 2014)
Aquatic weed Myriophyllum spicatum L. is one of the most invasive water plants known. In many countries, it is usually harvested and landfilled, where aerobic and anaerobic decomposition takes place. In this research, the ...
