In this paper influence of alginate encapsulation on point zero charge (pHpzc) and thermodynamic properties the natural Fe(III)- modified zeolite were investigated. The pHpzc was determined by using 0.1000 g samples 50 cm3 solution containing KNO3 in concentrations 0.0001–0.01 mol/dm3 for initial pH (pHi) range between 2 12. obtained 6.2 (NZA) 6.5 encapsulated with (FeA). Influence temperature adsorption lead investigated different ions (180–3200 mgPb2+/dm3) temperatures 30, 40 60oC. For...
In present paper, the influence of initial pH and concentration Pb2+ on its adsorption by natural (NZA) Fe(III)-modified zeolite-alginate beads (FeA) was studied. Results showed that modification starting materials have a positive effect their capacities (102 136 mg/g for NZA FeA, respectively). After encapsulation, mechanism lead both adsorbents changed ion exchange dominates. The best achieved > 3.8. Cation capacity, structural properties, hydrophobicity samples were also determined,...
The heavy metals content (HMs) was investigated in 14 different medicinal plants collected from the three regions Central Serbia, Zlatar, Sokobanja, and Kopaonik. concentrations of Cd, Cr, Ni, Hg Pb were determined: Cd (<0.03-2.72 mg/kg); Cr (<0.08-12.1 Ni (<0.08-12.2 (0.6-49.0 concentration below detection limit 0.06 mg/kg all samples. daily intake HMs due to ingestion 200 mL herbal infusion cases recommended prescribed by World Health Organization. estimated values for oral reference dose...
This research presented, for the first time, results of successful application waste press sludges, WSLP (plant lacquer and paint) WSEP (powdery enamel plant), from a wastewater treatment plant generated during heating device production in construction industry. The characterization its influence on cement paste, mortar, concrete properties showed that this material could be used as replacement (with maximum amount 20%) producing mortar concrete. Although sludge does not possess pozzolanic...
Indigo carmine is a commonly used industrial blue dye. To determine its concentration in commercially available food dye composed of mixture indigo and D-glucose, this paper characterizes it through (ATR, KBr) FTIR micro-Raman as well UV/Vis clock: Briggs-Rauscher (BR) oscillatory reaction methods. The was detected the bulk only by applying spectroscopy, indicating low percentage present. This research provides an improvement deviations from experimental Raman spectrum calculated...
Nanopowdered Ce1−xYbxO2−δ solid solutions (0 ≤ x 0.2) were synthesized by a self-propagating room temperature synthesis. XRD and SEM used to study the properties of these materials as well Yb solubility in CeO2 lattice. Results showed that all obtained powders with fluorite-type crystal structure nanometric particle size. The average size particles was approximately 3 nm. Electrochemical impedance spectroscopy for sintered pellets depicted it possible separate Rbulk Rgb interval 550–800 °C....
As a material for application in the life sciences, new composite material, geopolymer/CeO2 (GP_CeO2), was synthesized as potential low-cost solid electrolyte oxide fuel cells operating intermediate temperature (IT-SOFC). The materials were obtained from alkali-activated metakaolin (calcined clay) presence of CeO2 powders (x = 10%). Besides commercial powder, source ceria, two differently also used: by modified glycine nitrate procedure (MGNP) and self-propagating reaction at room (SPRT)....
The intent in this paper is to define how the batch equilibrium results of copper removal from a synthetic solution on natural zeolite can be used for prediction breakthrough curves fixed-bed system both and wastewater. Natural Vranjska Banja deposit, Serbia, has been fully characterized (XRD, chemical composition, DTA/TG, SEM/EDS) as clinoptilolite with cation exchange capacity 146 meq/100 g. maximum adsorption (qm) mono-component (synthetic solution) obtained using Langmuir isotherm model...
