Adsorption of Anthraquinone Dye AB111 from Aqueous Solution using Synthesized Alumina-Iron Oxide Doped Particles
(Science of Sintering, 2021)
Adsorption of anthraquinone dye Acid Blue 111 by alumina-iron oxide doped particles prepared by sol-gel method from aqueous solutions was studied. The adsorbent morphology was revealed by FESEM and the crystallographic ...
Ceria Particles as Efficient Dopant in the Electrodeposition of Zn-Co-CeO2 Composite Coatings with Enhanced Corrosion Resistance: The Effect of Current Density and Particle Concentration
(Molecules, 2021)
Novel Zn-Co-CeO2 protective composite coatings were deposited successfully from chloride plating solutions. Two different types of ceria sources were used and compared: commercial ceria powder and home-made ceria sol. ...
Efficient replacement of the radioactive sources in the gas-filled surge arresters construction for the insulation co-ordination at the low voltage level
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
The possibility of the classical response rate engineering and the long-term deconditioning of the gas-filled surge arresters is considered in this paper. The obtained results are compared with the same results obtained ...
Supercritical CO2 extraction of steroidal sapogenins from fenugreek (tngonella foenum-graecum l.) Seed
(Savez hemijskih inženjera, Beograd, 2020)
Supercritical CO2 extraction was applied on fenugreek (Trigonella foenum-graecum L., Fabaceae) seeds with the aim to define optimal process conditions to obtain the maximal extract yields content of steroidal sapogenins. ...
Optimization of Methanol Synthesis under Forced Periodic Operation
(Processes, 2021)
Traditionally, methanol is produced in large amounts from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts under steady state conditions. In this paper, the potential of alternative forced periodic operation modes ...
Amides as a model system of low molar mass algal organic matter. Influence on the adsorption of p-nitrophenol on activated carbon
(Elsevier, Amsterdam, 2020)
In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an ...
An Investigation into Mechanical Properties and Printability of Potential Substrates for Inkjet Printing of Orodispersible Films
(Pharmaceutics, 2021)
Inkjet printing is novel approach in drug manufacturing that enables dispensing precise volumes of ink onto substrates. Optimal substrate properties including suitable mechanical characteristic are recognized as crucial ...
Use of chènevotte, a valuable co-product of industrial hemp fiber, as adsorbent for copper ions: Kinetic studies and modeling
(Elsevier B.V., 2022)
In this study, a series of hemp shives (chènevotte) with different chemical compositions and properties, namely a raw (SHI-R), a washed with water (SHI-W), three samples chemically modified with KOH (SHI-OH), Na2CO3 (SHI-C) ...
Ambient air particles: The use of ion chromatography and multivariate techniques in the analysis of water-soluble substances
(Journal of the Serbian Chemical Society, 2021)
Seventeen water-soluble substances (of sodium, ammonium, potas-sium, magnesium, calcium, formate, methanesulfonate, glyoxylate, chloride, nitrite, nitrate, glutarate, succinate, malate, malonate, sulfate and oxalate) in ...
Modeling of disperse dye adsorption on modified polyester fibers
(University of Novi Sad, Faculty of Technology, 2020)
The results of the research on the ability of adsorption of dye on polyester fibers at a temperature of 98 °C are presented in this paper. The fibers were previously modified in aqueous solutions of NaOH, KOH or Al(OH)3. ...
