Equilibrium, kinetic and thermodynamic studies on removal of Cd(II), Pb(II) and As(V) from wastewater using carp (cyprinus carpio) scales
(Inst Materials Physics, Bucharest, 2013)
Unmodified farming carp (cyprinus carpio) scales were used as a biosorbent for the removal of Cd(II), Pb(II) and As(V) ions from aqueous solutions. The adsorption studies were conducted as a function of pH, contact time ...
Efficient As(V) removal by alpha-FeOOH and alpha-FeOOH/alpha-MnO2 embedded PEG-6-arm functionalized multiwall carbon nanotubes
(Inst Chemical Engineers, Rugby, 2017)
A novel adsorbents, 6-arm amino polyethylene glycol functionalized multiwall carbon nanotubes (PEG/MWCNT) loaded with alpha-FeOOH (Fe/PEG/MWCNT), and hybrid alpha-FeOOH/alpha-MnO2 nano-deposit (Fe-Mn/PEG/MWCNT) were used ...
Synthesis and characterization of interpenetrating polymer network based on sodium alginate and methacrylic acid and potential application for immobilization of TiO2 nanoparticles
(Wiley, Hoboken, 2015)
An interpenetrating polymer network (IPN) based on the sodium alginate (A) and partially neutralized poly(methacrylic acid) (MAA) was prepared by free radical polymerization followed by additional cross-linking of sodium ...
The enhanced removal of cationic dyes in binary system using novel copolymers with two kinds of acidic groups
(Elsevier Science Bv, Amsterdam, 2015)
In this study novel copolymer hydrogels based on methacrylic acid (MAA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) were synthesized by free-radical aqueous copolymerization and characterized. Derived P(MAA-co-AMPS) ...
Immobilization of horseradish peroxidase onto kaolin
(Springer, New York, 2016)
Kaolin showed as a very perspective carrier for the enzyme immobilization and it was used for the adsorption of horseradish peroxidase (HRP). The effects of the enzyme concentration and pH on the immobilization efficiency ...
Antioxidative, antifungal, cytotoxic and antineurodegenerative activity of selected Trametes species from Serbia
(Public Library Science, San Francisco, 2018)
In a last few decades mushrooms are increasingly attracting attention as functional food and sources of biologically active compounds. Several Trametes species have been used for centuries in traditional medicine of East ...
Testing of the efficiency of military devices for personal respiratory protection in relation to sub-micron particles of biological agents
(Inst Materials Physics, Bucharest, 2012)
The construction of biological weapons and tactics of its application dictate that dissemination of biological agents on the target has to be in the form of aerosols. The work was done on the effectiveness of filtration ...
Potential of Trametes species to degrade lignin
(Elsevier Sci Ltd, Oxford, 2013)
Well developed ligninolytic enzyme system in white-rot mushrooms is responsible for degradation of low degradable and lignin rich unused plant debris, which represents serious environmental ballast. The biological degradation ...
Influence of Microwave Heating on the Polymerization Kinetics and Application Properties of the PMMA Dental Materials
(Wiley, Hoboken, 2011)
The effects of heating mode (conventional isothermal heating (CIH) and microwave isothermal heating (MWIH) on the kinetics of polymerization and the properties important for the application (residual monomer, hardness, and ...
The preliminary comparative analysis of different routes for tio2 nanoparticles synthesis and their deposition on textiles. The methyl-orange degradation and vx detoxication study
(Inst Materials Physics, Bucharest, 2013)
The world-wide use of pesticides together with the possibility of chemical warfare agent's usage in military actions, terrorist attacks or in accidents, increased the risks of chemical contamination occurrence and consequently ...
