AB  - The aim of this paper is to investigate the application of modified lignin-based adsorbent for
successful removal of dichromate ions and sodium diclofenac (DCF) from aqueous solutions by
adsorption. Modification of lignin-based adsorbent (LBA) was performed by inverse suspension
copolymerization with branched poly (ethylene-imine) using epichlorohydrin as a crosslinker. After
that, the functionalization of LBA was performed by chemical binding of amino modified nanoparticles
of manganese (IV) oxide, in order to improve the adsorption properties. Characterization of
LBA-MnO2 microspheres was performed using FT-IR spectrometer, Scanning electron microscopy,
BET/BJH analysis. The adsorption process was performed in a batch adsorption system. The results
were obtained with the help of kinetic and corresponding equilibrium adsorption isotherms. The
maximum adsorption capacity for the removal of Cr2O7
2- ions and DCF was obtained using the
Langmuir model and amounts to 88.4 mg g-1 and 52.8 mg g-1 at 45 °C, respectively. Adsorption
kinetics was described using a second-order pseudo model. Based on thermodynamic parameters, it
was concluded that the adsorption process is an endothermic and spontaneous. Based on the obtained
results, LBA-MnO2 material possess very good adsorption properties.

AB  - The unique chemical structure of lignin shows the possibility of its application as a basic material for
the sorption of various pollutants from water. In this paper, the newly synthesized porous lignin-based
material was used to remove Cr(VI) ions. Modified lignin microspheres (LMS) were synthesized by the
process of inverse copolymerization of kraft lignin with poly (ethylene-imine), and amino modified
iron oxide (magnetite) using epoxy-functionalized cross-linker. The shape of obtained adsorption
material was partially spherical to spherical. The functionalization was performed to improve the
pollutant removal capacity. Structural and surface characteristics of the LMS microspheres were
characterized by Brunauer-Emmett-Teller method (BET), Fourier transform infrared spectroscopy
(FTIR), scanning electron microscopy (SEM) and point of zero charge pH (pHPZC). The maximum
adsorption capacity for oxyanion Cr(VI) was 77.024 mg g-1obtained by Langmuir adsorption isotherm
at 35°C. Based on kinetic studies, the adsorption process follows a pseudo second-order model.
Thermodynamic parameters have shown that the adsorption process is endothermic and spontaneous.
LMS is an environmentally friendly, cost-effective and therefore promising adsorbent for the removal
of Cr(VI) with efficient adsorption and reusability.

AB  - Adsorbenti na bazi oksida Fe3+ i Cr3+predmet su brojnih istraživanja. Interkalacioni sloj
vermikulita koristan je medijm za taloženje nanočestica. Zbog svoje relativno velike površine,
kapaciteta katjonske izmene i prirodnog obilja vermikulita, ovaj liskunski mineral i njegovi kompoziti
mogu biti valorizovani kao potencijalni adsorbenti. U ovoj studiji kompozit oksida
Fe3+/Cr3+/ekspandirani vermikulit (Fe2O3 / Cr2O3 / EV) pripremljen je metodom in-situ. Kompozitni
i osnovni materijal karakterisan je Furijeovom transformacijom infracrvene spektroskopije (FTIR),
rendgenskom difrakcijom (XRD), skenirajućom elektronskom mikroskopijom (SEM), a određeni su i:
specifična površina BET-om (SBET), kapacitet katjonske izmene (CEC) i pH tačke nultog
naelektrisanja (pHPZC). Adsorpciona svojstva Fe2O3 / Cr2O3 / EV i EV ispitivana su u šaržnom
sistemu na pH blizu pHPZC za uklanjanje Ni (II) iz vode. Uzimajući u obzir parametre procesa kao
što su vreme kontakta, masa adsorbenta i temperatura određeni su tip adsorpcije, termodinamički i
izotermski parametri (Lengmir i Frojndlih) i parametri brzine adsorpcije. Rezultati kinetičkih studija
dali su dobre korelacije sa modelom pseudo - drugog reda i Veber - Morisovim modelom. Uzimajući
u obzir činjenicu da je EV imao niske vrednosti CEC i specifične površine, dobijeni kompozit ima
umerenu adsorpcionu sposobnost (22,9 mg/g).
