AB  - Infant nutrition is essential for their growth and development. This research aims to determine the total antioxidant capacity of the infant food for preterm infants and indicate adequate methods for testing the quality and biological value of milk and infant food. The total antioxidant capacity (TAC) was determined in human milk and an infant formula for premature infants. The determination of the total antioxidant capacity was made using cyclic and differential pulse voltammetry, potentiometry and electron paramagnetic resonance spectroscopy. The results of three comparative electrochemical methods indicate that human milk has a higher antioxidant potential compared to infant formula, which contributes to better physiological development of the child. Fenton-based electron paramagnetic resonance spectroscopy method provides additional insight into TAC analysis, whereby a carbon-centered radical and an ascorbyl radical are formed in infant food. All methods can be used to determine TAC, since the results obtained individually with each method follow the same trend.

AB  - Water contaminated with diesel oil is one of the great challenges in waste water management. It is crucial to remove the water soluble fractions (WSF) from water in order to avoid toxic effects of these compounds and to meet the discharge regulations set by the environmental authorities. Biochar sorbents have generated a lot of attention as a new type of material due to their low cost origin and surface properties which lead to exceptionally high sorption capacities in water-pollution separation process. In this study, we have reported the synthesis and characteristics of novel biochar sorbent made from waste lignocellulosic biomass (peach stones) and evaluated its possible application in removal of WSF from synthetic wastewater. The synthesized biochar materials were characterized using scanning electron microscopy (SEM), Fourier (FTIR) and Brunauer, Emmett and Teller (BET) technique, while the elemental analysis was also done. Characterisation of peach stone biochar (PS-B) indicated multi porous high surface area (159.1 m2/g), with an average pore diameter of 2.66 nm. FTIR results indicated the presence of more aromatic compounds in biochar compared to peach stones. The sorption experiments were performed in batch system with mixing, with initial WSF of diesel components of 20 mg/L. The application of peach stone biochar (PS-B) resulted in more than 95% removal of diesel WSF, with reaching equilibrium after 5h of contact (under described operational conditions). Sorption mechanism can be described as multilayer chemisorption process, well described by Freundlich equation, which was also confirmed by pseudo-second order equation. Ecotoxicology tests have shown a decrease of toxicity of contaminated water on A. fischeri after the treatment of water by biochar sample. Therefore these forms of carbon based sorbents have great potential to be good sorbents of petroleum hydrocarbons WSF and can be successfully applied for their removal in water treatments

AB  - Water contaminated with diesel oil represents one of the greatest challenges in waste water management. Water soluble fraction (WSF) is of particular interest because of its toxicity to aquatic organisms and discharge regulations set by environmental authorities. Biochar sorbents have attracted great attention, due to their low cost origin and advantageous properties as well as high sorption capacities in sorption processes. In this study, we have reported the synthesis and characteristics of novel biochar sorbent made from waste lignocellulosic biomass (peach stones (PS)) and evaluated its possible application in removal of diesel WSF from synthetic water. Physiochemical characteristics of the biochar sample were analysed by scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) method, and Fourier-transform infrared spectroscopy (FTIR), along with the elemental analysis. Characterisation of PS biochar (PS-B) indicated high multi porous surface area (159.1 m(2) g(-1)) with the average pore diameter 2.7 nm. FTIR results indicated higher presence of aromatic compounds in PS-B as compared to PS. The sorption experiments performed in a batch system using PS-B resulted in more than 95 % removal of diesel WSF, reaching equilibrium after 5 h. Equilibrium data were well fitted by Freundlich isotherm, while the pseudo-second order equation fitted well the kinetic data, indicating chemisorption involving valency forces through the sharing/exchange of electrons between the sorbent and PS-B. Applications of ecotoxicology tests based on a microbial biosensor (Aliivibrio fischeri) have shown a significant toxicity reduction of water sample after the treatment with biochar.
