AB  - U ovom radu proučavana je primena adsorbenasa na bazi modifikovanog
sintetskog zeolita - mordenita za uklanjanje jona Cu 2+ i Pb 2+ iz vodenih rastvora. U
cilju poboljšavanja njegovih adsorpcionih svojstava zeolit je modifikovan
korišćenjem (3-aminopropil)trietoksisilana. Preliminarni rezultati pokazali su da
modifikovani mordenit postiže adsorpcioni kapacitet od 21,0 i 63,2 mg/g za Cu 2+ i
Pb 2+ , redom. Adsorpcija oba jona prati kinetiku modela pseudo-drugog reda. Ovaj
model podrazumeva hemijsku interakciju između jona metala i funkcionalnih
grupa na površini silanizovanog mordenita. Dobijeni rezultati ukazuju da je
mordenit modifikovan silanima pogodan adsorbens za potencijalno uklanjanje
jona teških metala iz otpadnih voda.

AB  - Mushrooms are widely investigated and recognized as perspective materials for the removal
of various pollutants from wastewater effluents. In this study, mosaic puffball Handkea
utriformis was tested as a new biodegradable, but relatively stable material for Cd2+
adsorption from aqueous mediums. The fruiting body of Handkea utriformis goes through the
process of autodigestion, during which their inside – gleba is turned into a powdery, sporebearing
mass, and the lower portion of the fruiting body – subgleba, into a dark, dry, spongy
mass. The impurities and spores present on the surface of the subgleba can be removed in a
simple process of purification with acidic and alkaline solutions. The purification decreases
the hydrophobicity of the surface of this material, and therefore increases the number of
surface functionalities, knowing that subgleba consists of sugars, proteins and polymeric
pigments (melanins). The subgleba purified with 0.1M HCl and 0.1M NaOH (Sp) was used
for the removal of Cd2+ from the aqueous solution. The efficiency of the material for
adsorption of Cd2+ was investigated in a batch system under the constant initial concentration
of adsorbate and pH and different concentrations of the adsorbent. Composition and surface
morphology were characterized by using FT-IR spectroscopy, SEM and EDX analysis.
Concentrations of Cd2+, before and after adsorption, were determined by using Atomic
Absorption Spectroscopy (AAS). The Langmuir and Freundlich isotherm models, as well as
kinetic models, were evaluated to correlate experimental data. The results showed that kinetic
data were well fitted by a pseudo-second-order model. Isotherms studies revealed that the
best fit was achieved with the Langmuir isotherm model with a maximum adsorption capacity
of 15.2, 19.1 and 25.0 mg g-1 at 25, 35 and 45ºC, respectively.

pollutants are of organic origin and their removal will be carried in this work out using advanced
oxidation processes using ozone, and ozone in combination with ultrasound to achieve water

Two methods of tannin modification were applied: direct method using ammonium hydroxide, ammonium hydroxide/ammonium chloride buffer or diethylenetriamine (DETA); and a two-step method including tannin modification with epichlorohydrin (ECH) in first step to produce epoxy modified tannin, ET, and further modification with heteroaromatic amines or linseed oil fatty acids (LFA) in second step. The obtained anticorrosive additives were characterized using ATR-FTIR, 1H and 13C NMR spectroscopies and elemental analysis. Epoxy, amino, hydroxyl, acid and iodine values of the synthesized inhibitors were determined according to standard methods. The prepared alkyd coating with tannin inhibitors was tested according to standard SRPS EN ISO 4628 method. Anticorrosive coating containing modified tannin based additive showed increased anticorrosive properties, good adhesion and coverage comparing to the coating with zinc phosphate additive. The alkyd coating films based on ET-LFA and ET modified with 2-amino-5-mercapto-1,3,4-thiadiazole showed best anticorrosive results.

AB  - Point of zero charge (PZC) is one the most valuable parameter of adsorbent preparation process, in
wastewater management. Although, this parameter may be determined measuring the electrokinetic potential (zetta
potential) as the function of pH; material engineers oftenrely on pH PZC value which may be easily determined and
can give usefuladsorbent properties duringexploitation. Samples from previous study are characterized and their pH
PZC values are determined. Provided results are such intriguing since they brought conclusions that those values can
be explained by process parameters of the particular sample preparation. Sample marked as Cr2O3/Fe3O4/EVer have
lowest pH PZC value (4.75) and sample marked as MnFe2O4/EVer highest pH PZC value (7.47). Another study in this
paper showed that pH PZC value could be easily increased or decreased by simple base or acid treatment, respectfully.
As expected, samples treated with bases or prepared in alkali medium have greater adsorption capacity towards
cation species, up to 20 % more than base material in the case MnFe2O4/EVer.
