AB  - U radu je prikazana sinteza visokoefikasnih antikorozivnih premaza dobijenih iz alkidnih smola (AR) baziranih na proizvodima glikolize iz otpadnog poli(etilen tereftalata) (PET). Glikolizati PET-a dobijeni postupkom katalitičke depolimerizacije uz pomoć trimetilolpropana (TMP) i dipropilen glikola (DPG), su korišćeni kao zamena polihidroksilne komponente tokom sinteze AR smola. Sintetisani glikolizati i AR smole okarakterisane su primenom FT-IR i 1HNMR spektroskopije i određena im je vrednost kiselinskog, jodnog i hidroksilnog broja. Sintetisanim AR smolama, kao i antikorozionim alkidnim premazima određena su sledeća svojstva: debljina suvog filma, adhezivnost, bubrenje, korozivnost, prskanje i odslojavanje prema SRPS EN ISO standardima. Alkidne smole su dobijene u visokom prinosu i pokazale su dobra fizičko-mehanička svojstva, adhezivnost i sjaj premaza (≤85 %), dok su antikorozioni alkidni premazi na bazi AR1 i AR3 pokazali najbolje rezultate otpornosti na koroziju. Najefikasnija kombinacija katalizatora sušenja je 0.5 mas.% Ca, 0.03 mas.%, Co i 0.45 mas% Zr.
AB  - Synthesis of high-performance anticorrosive coatings obtained from alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET glycolyzates, synthesized by catalytic depolymerization with trimethylolpropane (TMP) and dipropylene glycol (DPG), were used as replacement of part of the polyhydroxylic component during the ARs synthesis. The obtained glycolyzates and ARs were analyzed using FT-IR and 1HNMR spectroscopy and acid, iodine, and hydroxyl value were determined. Thickness, adhesion, swelling, corrosion, spraying and layering of the synthesized ARs, as well as alkyd coating film were determined in accordance with SRPS EN ISO standards. ARs were produced in high yields and FT-IR and 1NMR analysis results confirmed assumed structures. All synthesized ARs show good elasticity, flexibility, adhesion and the gloss values are greater than 85 %, and the alkyd coating films based on AR1 and AR3 showed best corrosion results. The most effective dryer catalyst combination was 0.5 wt.% Ca, 0.03 wt.%, Co and 0.45 wt.% Zr.

AB  - Ecobiological study of medicinal plants includes the analysis of particular soil features and the ecological indexes of plant species as site indicators. Two experimental serpentine areas in northwest and central Serbia were selected to identify the potential limiting factors for medicinal plant harvesting. Soil analysis is done according to ICP methodology ICP Forest Manual, Part III, Soil Sampling and Analysis (1998). Floristic and phytocoenological investigations were carried out by Wasthoff-van der Maarel (1973). The assessment of soil quality is based on the calculation of indicator values of available nitrogen (N), heavy metals, and the sensitivity to acidification. According to our results, N (12.1-17.5), acidification (7-12), and indicator values for some heavy metals (0.3-46.5) show a low biological availability. Medicinal plant species at the investigated areas have low values of ecological indexes: N (2.41-2.82), moisture (2.45-2.70) and soil acidity (3.35-3.70). Hydrothermic conditions indicate the predominant presence of sub-xerophytes, semi-sciophytes and mesothermic species. These types of plant species are recommended for exploitation.
