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  - In-depth kinetic and column adsorption study for diclofenac, DCF, heavy-metal and oxyanions adsorption on highly effective amino-functionalized lignin-based microsphere adsorbent (A-LMS) is examined. The A-LMS was synthesized via inverse suspension copolymerization of industrial kraft lignin with the amino containing grafting-agent (polyethylene imine), and an epoxy chloropropane cross-linker. The batch adsorption results indicated process spontaneity and feasibility of a high removal capacity: DCF(151.13) >>Cd2+(74.84)>Cr(VI)(54.20)>As(V)(53.12)>Ni2+(49.42 mg g(-1)). The quantum chemical calculated interaction energies reveal stabilization of the A-LMS/DCF complex through the electrostatics and van der Waals interactions. The results from the pseudo-second order and Weber-Morris fitting indicate a fast removal rate; thus, column tests were undertaken. The single resistance mass transfer model, i.e. the mass transfer (kfa) and diffusion coefficient (Deff), shows pore diffusional transport as a rate limiting step. The fitting of the fixed bed column data with empirical models demonstrates the influences of flow rate and adsorbate inlet concentration on the breakthrough behavior. Pore surface diffusion modeling (PSDM) expresses mass transport under applied hydraulic loading rates, calculated breakthrough point adsorption capacities: Cd2+(58.1)>Cr(VI)(54.1)>As(V)(50.9)>>Ni2+(42.9 mg g(-1))), without performing the experimentation on a full pilot-scale level, further confirms the high applicability of the A-LMS biobased adsorbent.

AB  - This paper covers the results of pelletizing fly ash in order to obtain pellets, with satisfied mechanical properties, that can be used in wastewater treatments. Serbian fly ash from “Nikola Tesla” power plant was used as a low cost sorbent. Fly ash was subjected to elementary and XRD analysis. Portland cement was used as a pelletizing agent along with the plastification agent. The mechanical properties of pellets were investigated using different methods such as: pressure resistance, impact resistance, resistance to abrasion, and disintegration in water. The best results were obtained with the addition of 10 % of cement along with the plasticizer.

AB  - Industrial wastewater contains recalcitrant organic compounds with a very complex chemical structure, built of molecules with long chains of carbon atoms and attached different functional groups. Chemical or biological treatments used for removal of these compounds are being replaced with more efficient non-commercial wastewater treatments. Advanced oxidation processes overcome limitations of conventional methods regarding formation of by-products during degradation of recalcitrant organic compounds. The Fenton process, or use of the Fenton's reagent, has became one of the most utilized processes due to simplicity, economy and accessible amounts of ferrous iron and hydrogen-peroxide, which are used in the process. In specific, the Fenton's reagent is a catalytic-oxidative mixture of these two components. The ferrous iron Fe2+ initiates and catalyzes decomposition of H2O2, resulting in generation of hydroxyl radicals, which are the main radical species in the process able to detoxify several organic pollutants by oxidation. In addition, other mechanisms besides formation of hydroxyl radicals may occur during the Fenton process and participate in degradation of target pollutants. Generally, the treatment efficiency relies upon the physical and chemical properties of target pollutants and the process operating conditions. The main disadvantage of the Fenton process is production of sludge formed by iron hydroxide at certain pH values. An alternative solution for this problem is application of this process in fluidized bed reactors. This paper presents an overview of Fenton and photo-Fenton processes in dispersed systems for removal of different industrial wastewater pollutants. The most important process parameters, required for efficient degradation of recalcitrant organic compounds are also described, such as the catalyst type, pH value, temperature, H2O2 concentration and retention time. Strict control of Fenton process parameters in fluidized bed reactors at desired values can bring these systems to the commercial use.
