-Introduction. Apricots (Prunus armeniaca L.) have an important role in Serbia's fruit production. Average annual production of 25,035 t generates approximately 1,577 t apricot stone (AS) waste and most of it ends up in landfill sites. In order to minimize the environmental impact, an investigation of the possible use of AS was done by developing a biosorbent for wastewater treatment. Materials and methods. AS waste from the fruit processing industry was used to remove Cu(II) ions from water solution by batch adsorption techniques. This solid waste residue was characterized by FTIR, SEM and EDX. The effects of pH, contact time, metal concentration and biosorbent dosage on the process of biosorption were studied. Results and discussion. Obtained FTIR results confirm that the uptake of Cu(II) ions from aqueous solution involves carboxylate moieties from lignin and fatty acids. Also, the presence of seeds in the AS blend significantly increased biosorption performance providing active sites important for the sorption process. The ion exchange mechanism was also confirmed. The best fitting adsorption model is the Langmuir model and the maximum biosorption capacity (q max ) is 4.45 mg L −1 at pH 5.0. Biosorption of the Cu(II) ions follows a pseudo secondorder kinetic model. According to thermodynamic parameters the biosorption process is endothermic and spontaneous. Conclusion. Numerous biosorbents were investigated for biosorption of Cu(II) ions from aqueous solution, but no report on application of untreated AS waste has been found in literature. This preliminary study confirmed that this material can successfully and rapidly remove dissolved copper ions from dilute solutions.Keywords: Serbia / apricot / Prunus armeniaca / waste management / biosorption / copper ions Résumé -Application des déchets de noyaux d'abricot issus de l'industrie agro-alimentaire à la dépollution : étude de la biosorption du cuivre. Introduction. L'abricot (Prunus armeniaca L.) tient une place importante dans l'économie de la Serbie. La production annuelle moyenne de 25 035 t génère environ 1 577 t de déchets de noyaux d'abricots (AS) dont la plus grande partie se retrouve dans des sites d'enfouissement. Afin de minimiser l'impact environnemental de ces déchets, une l'utilisation possible des AS a été envisagée, visant à développer un biosorbant pour le traitement des eaux usées. Matériel et méthodes. Les déchets AS provenant de l'industrie agro-alimentaire ont été utilisés pour éliminer les ions Cu (II) de solutions aqueuses par des techniques d'adsorption par lots. Le résidu des déchets solides a été caractérisé par spectroscopie infrarouge à transformation de Fourier (FTIR), microscopie électro-nique (SEM) et radioscopie à dispersion d'énergie (EDX). Les effets du pH, du temps de contact, de la concentration et du dosage du métal sur le biosorbant ont été étudiés au cours du processus de biosorption. Résultats et discussion. Les résultats obtenus par FTIR confirment que l'absorption des ions Cu (II) de la solution aqueuse met e...

“…With mowing, the amount of unwanted aquatic weed from lake is being significantly reduced (approximately 350-400 m 3 per harvesting cycle) The harvested plant material is placed in an open landfill used specifically for this purpose without turning. Samples of compost were taken from the landfill surface (1 year old) [13].…”

“…Due to vegetative reproduction and forceful growth dense stand considerably impacts water flow and clog industrial and potable water supply systems, blocks sunlight for native aquatic plants and creates habitats favorable for mosquitoes (Aiken et al, 1979). Methods for growth control are physical (harvesting), chemical and biological (Milojković et al, 2014) Myriophyllum spicatum has been investigated for their potential in heavy metal removal. Mechanisms of metal removal by biosorption can be classified as: extracellular accumulation/precipitation, intracellular accumulation and cell surface sorption/precipitation (Rai et al, 2002).…”

Directive 1999/31/EC requires that biowaste with more than 3% organic content isn't accepted for landfilling directing toward more efficient use of biological material from the landfill. Myriophyllum spicatum is an aquatic weed which grows on every continent except Antarctica and it is noted for its capability to cause different problems, so its growth must be controlled. Utilization of bio-waste in the bioeconomy can be achieved with biosorption. In this study was investigated M. spicatum/alginate (5:1) biosorbent (MsA) for the removal of Pb(II) ions from aqueous solutions. MsA was characterized by Fourier transform infrared spectroscopy. The batch equilibrium was expressed by 5 isotherms and Redlich-Peterson isotherm model provided the best fit with the experimental data. Since, alginate-immobilized M. spicatum beads have superb Pb(II) uptake 200 mg/g they are appropriate cost-effective, environmental friendly biosorbent with potential application for continuous flow reactors. Managing and processing bio-waste must be deployed and integrated to meet the requirements of the sustainability.
