The removal of Pb(II), Cd(II), Cu(II), and Zn(II) from aqueous solutions using (un)modified Serbian interstratified montmorillonite/kaolinite clay as an adsorbent was investigated. modified by mechanochemical activation for different time periods. X-ray diffraction patterns particle size distributions were used to characterize the samples. Batch adsorption studies conducted optimize various conditions. equilibrium established within 60 min, maximum occurred in pH range 4.5–6.5. milled clays...
Modified activated carbon cloth is prepared by mechanochemical modification of viscose rayon cloth. The effects different milling atmospheres, in the air and inert conditions, were investigated. Changes kind number acidic basic surface groups on cloth, upon modification, as well before after sorption arsenic determined. Higher responsible for removal ions was achieved under conditions. Breakage collapse cylindrical fibers, decrease particle sizes, change shape consistency particles, increase...
Abstract In this study the application of home-made unmodified (GC) and bulk modified boron doped glassy carbon (GCB) electrodes for voltammetric determination linuron was investigated. The were synthesized with a moderate temperature treatment (1000°C). Obtained results compared electrochemical using commercial electrode (GC-Metrohm). peak potential (E p ) oxidation in 0.1 mol dm−3 H2SO4 as electrolyte similar all applied electrodes: 1.31, 1.34 1.28 V GCB, GC GC-Metrohm electrodes,...
A sensitive method for the determination of six varying polarity pesticides (imidacloprid, acetamiprid, carbendazim, simazine, linuron, and tebufenozide) based on a solid-phase extraction disk with multiwalled nanotubes is proposed.A dispersion in surfactant aqueous solution (Triton X-100) was used preparation disk. The effect functional groups examined by applying temperature-programmed desorption. It found that this treatment increased amount oxygen treated comparing untreated ones....
In the present work cobalt ferrite nanospheres (CFO NS) were prepared via one-step, templatefree solvothermal method and used as a magnetic adsorbent of chromium(VI) ions. The synthesized materials characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM) vibrating sample magnetometry (VSM). XRD results confirmed cubic spinel structure CFO NS while SEM revealed sphere-like morphology with diameters in range 100-300 nm. TEM images showed that each...
Transport behaviour of Lu(III) across a polypropylene hollow fibre-supported liquid membrane containing di(2-ethylhexyl)phosphoric acid (DEHPA) in dihexyl ether as carrier has been studied. The donor phase was LuCl(3) the buffer solution consisting 0.2 M sodium acetate at pH 2.5-5.0. A miniaturised system with single fibre operated batch mode. concentration determined by indirect voltammetric method using Zn-EDTA complex. effect and volume phase, DEHPA organic (liquid membrane) time...
In this study, the mass transport resistance in liquid‐phase microextraction ( LPME ) a single hollow fiber was investigated. A mathematical model has been developed for determination of overall transfer coefficient based on acceptor phase an unsteady state. The estimated from time‐dependent concentration extracted analyte while maintaining constant donor phase. It can be achieved either using high volume to ratio or tuning extraction conditions obtain low‐enrichment factor, so that sample...
Extraction of Lu(III) from an aqueous LuCl3 solution at pH 3.5 into organic phase containing 5% (v/v) di(2-ethylhexyl)phosphoric acid (DEHPA) in di-n-hexyl ether (DHE) immobilized within a polypropylene hollow fiber membrane and simultaneous back-extraction 2 mol dm–3 HCl has been investigated using two miniaturized supported liquid (SLM) systems: (i) single membrane, with stagnant acceptor the lumen, immersed donor reservoir; (ii) U-shaped module closed-loop recirculation phases through...
Monodispersed polyethylene glycol diacrylate (PEGDA)/acrylic acid (AA) microgels with a tuneable negative charge and macroporous internal structure have been produced using Lego-inspired droplet microfluidic device. The surface of was controlled by changing the content AA in monomer mixture from zero (for noncharged PEGDA beads) to 4 wt%. macroporosity polymer matrix introduced adding 20 wt% 600-MW (PEG) as porogen material into mixture. successfully leached out acetone after...
Abstract Lutetium has been determined by differential pulse anodic stripping voltammetry in an acidic solution containing Zn-EDTA. (III) ions liberated zinc (II), which was preconcentrated on a hanging mercury drop electrode and stripped anodically, resulting peak current linearly dependent lutetium concentration. Less than 0.4 ng mL−1 could be detected after 2 min deposition.
Austenitic stainless steels are widely used in nuclear medicine due to their good corrosion resistance and superior mechanical properties. Administration of radiopharmaceuticals is done via steel needles the possibility very high unfavorable environment that rich chlorides influence radioactive radiation. The effect gamma radiation on behaviour 304 saline bidistilled water was investigated by electrochemical measurements morphological/microstructural characterization performed SEM. results...
This paper analyzes the conditions for membrane extraction of pesticides using ACD / LABS 12 program. The program contains a large database more than 2000 compounds and their ionized species, determining pKa, further analysis includes 600 new confirmed by Hammett?s equation, which gives precise values logD solubility. 16 different classes (organophosphates, carbamates, carbamidas, neonicotinoids etc.) polarities commonly used in Serbia were examined. is to calculate logD, pKa solubility at...
