Re-entrant spin glass transition in LiCr0.175mn1.825O4 spinel
(Society of Physical Chemists of Serbia, 2006)
Magnetic properties of Cr3+ substituted LiMn2O4 spinel have been investigated by measuring both temperature and field dependence of DC magnetization, as well as temperature dependence of AC susceptibility. Obtained results ...
Derivative spectrophotometric determination of partition coefficient of hydrochlorothiazide between cetyltrimethylammonium bromide micelles and water
(Society of Physical Chemists of Serbia, 2004)
The interaction of hydrochlorothiazide (HCT), benzothiadiazine diuretic, with cationic surfactant cetyltrimethylammonium bromide (CTAB) was studied as a model system for drug/membrane interactions. From the dependence of ...
Study of copper adsorption on aminofunctionalized macroporous poly(gma-co-egdma)
(Society of Physical Chemists of Serbia, 2006)
Macroporous crosslinked copolymer of glycidyl methacrylate and ethylene glycoldimethacrylate (PGME) was synthesized by suspension copolymerisation and modified by ring-opening reaction of epoxy groups with ethylene diamine, ...
Kinetics of heavy metal sorption on macroporous vinylpyridine based copolymer
(Society of Physical Chemists of Serbia, 2006)
Sorption of copper, nickel and cobalt on macroporous crosslinked copolymer of 4- vinylpyridine and ethylene glycol dimethacrylate, PVPE, was studied. The kinetics models (pseudo-first and pseudo-second order equations) ...
Determination of the ionization constants of 2,4-DIIODO-6-methylphenyl carbamoylmethyl iminodiacetic acid
(Society of Physical Chemists of Serbia, 2004)
The ionization constants of 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid were determined: pK1 1.3 (the first carboxylic group), pK2 2.52 (the second carboxylic group), pK3 5.86 (amino group) and pK4 10.85 ...
Physico-chemical characterization of 90Y-labeled antimony trisulfide colloid and comparison with 99mTc-labeled one
(Society of Physical Chemists of Serbia, 2008)
In radionuclide therapy, the importance of 90Y as a beta-emitting radionuclide is increasing rapidly. The properties of the 90Y-labeled antimony trisulfide colloid (Sb2S3) were compared with the 99mTc-labeled one. Labeling ...
HPLC and spectrophotometric investigation of the formation of Sn(II)-p-aminohippuric acid complex in perchlorate medium
(Society of Physical Chemists of Serbia, 2004)
The complex equilibrium in tin(II)-p-aminohippuric acid (PAH) solutions in perchlorate medium was investigated. HPLC, spectrophotometric and pH-metric methods were used. The experimental results have shown that week ...
Environmental isotope investigation of the river catchments
(Society of Physical Chemists of Serbia, 2006)
Heavy metal content of pm10 and pm2.5 within urban area of Belgrade
(Society of Physical Chemists of Serbia, 2006)
An assessment of air quality of Belgrade was performed by determining the trace element content in airborne PM10 and PM2.5 in two years period. Samples were collected at two locations in a heavy polluted area. The ...
Precipitation chemistry in the Velika Morava catchment
(Society of Physical Chemists of Serbia, 2006)
Bulk precipitation chemistry on a daily basis was studied for seven years (1998-2004) at three meteorological stations (Smederevska Palanka, Kraljevo, Niš) in the Velika Morava catchment. Samples were analyzed for the ...
