The human health risks of cadmium (Cd), lead (Pb), and nickel (Ni) in fifty regular slim cigarette brands available the Serbian market were evaluated. Distributions on per-cigarette basis concentrations these metals, as determined by graphite furnace atomic absorption spectrometry, used inputs probabilistic risk assessment. contents metals cigarettes varied significantly. Larger quantities studied observed than cigarettes, but concentration levels per tobacco mass higher cigarettes. metal...
The specific activities of natural radionuclides ((40)K, (226)Ra and (232)Th) Chernobyl-derived (137)Cs were measured in soil profiles representing typical types Belgrade (Serbia): chernozems, fluvisols, humic gleysols, eutric cambisols, vertisols gleyic fluvisols. influence properties content stable elements on radionuclide distribution down the (at 5 cm intervals up to 50 depth) was analysed. Correlation analysis identified associations (40)K, with fine-grained fractions. Significant...
Practical aspects of Lagenaria vulgaris shell conversion to activated carbon were examined along with its use in ranitidine adsorption. Kinetics and isotherms adsorption onto (LVC) correlated several theoretical models. The best fit was found the case Langmuir pseudo-second-order model indicating monolayer influence pH under kinetic study showed slightly hindered below 4. optimal adsorbent dosage set 1 g/L. LVC characterized by complementary techniques, including wet chemical techniques such...
Adsorption of a cationic phenothyazine dye methylene blueonto activated carbon prepared from pine cones was investigated with the variation in parameters contact time, concentration and pH. The kinetic data were found to follow pseudo-second-order modelclosely. equilibrium best represented by Langmuir isotherm maximum adsorption capacity 233.1 mg g-1. favored using higher solution Textural analysis nitrogen used determine specific surface area pore structure obtained carbon. Boehm titrations...
In this study, modified sol-gel method was employed to synthesize the pure and Zr-doped titania catalysts. Brunauer-Emmett-Teller (BET) applied determine porosity, X-ray diffraction (XRD) analysis used study crystal structure, scanning electron microscopy (SEM) investigate morphology Fourier transform infrared spectroscopy (FTIR) examine surface properties/total acidity of obtained catalysts samples. Photocatalytic activity tested in reaction violet (CV) dye decolourization/degradation under...
A high consumption of solid fats is linked to increased inflammation and a risk cardiovascular diseases. Hence, in recent years, there has been increasing interest the development oleogels as fat substitute food products. Oleogels are edible gels that contain large amount liquid oils entrapped 3D network can potentially be applied spreads, bakery goods, meat, dairy products order lower their saturated content while maintaining desirable texture mouthfeel. In this work, alginate cryogels were...
Background: Terrestrial radiation emitted from naturally occurring radionuclides, such as 40K and radionuclides the 238U 232Th series their decay products represent main external source of irradiation to human body. The purpose this study was provide a preliminary assessment doses terrestrial exposure population in Serbia estimate potential hazard for inhabiting investigated areas. Methods: gamma dose rates, indexes, annual effective due (238U, 40K) were calculated based on activities soil...
Carbon cryogel (CC) has been prepared through sol gel polycondensation of resorcinol with formaldehyde in basic aqueous solution followed by freeze-drying and carbonization. Porous properties CC analyzed gravimetric McBain method confirmed the expected surface area degree mesoporosity. Obtained powdered material was used for removal pesticide imidacloprid from solutions under regular batch adsorption procedure. A set several isotherm models including Langmuir, Freundlich, Temkin,...
The aim of this work was to estimate the health and radiation hazard due external irradiation from terrestrial radionuclides in Stara planina Mt. region, which is important because past uranium mining activities on mountain. Soil samples were collected inside flotation processing facilities, their surroundings more distant locations, i.e. areas considered certainly affected, potentially unaffected by former ore activities. radiological risk assessments done calculating six main parameters,...
Resorcinol-formaldehyde carbon cryogel has been prepared, characterized and used for the removal of commonly herbicide clopyralid from aqueous solutions under varying experimental conditions. Carbon shown a relatively high specific surface area, significant mesoporosity an amorphous structure. A set following isotherm models to interpret equilibrium data: Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Jovanovic, Hurkins-Jura, Helsey model. Several have fitted well although calculated...
