AB  - Recycling of printed circuit boards (PCBs) is an extremely complex and sensitive process. Physicochemical
characterization of printed circuit boards is significant for choosing the optimal
processing procedure. The aim of this research was the physico-chemical characterization of the
boards and the separated fractions after cutting on a shredder and magnetic separation. Separated
fractions (metal granulate, magnetic fraction, and plastic) were leached in three consecutive phases
by use of sulfuric acid, nitric acid, and aqua regia. The experiments were performed on the
fractions obtained by processing 100 kg of the sample and were compared with the results obtained by the chemical analysis of the sample obtained by manually unfolding 10 PCBs. Also, the grain size analysis of each separated fraction was determined.
AB  - Reciklaža štampanih ploča (PCBs) je izuzetno složen i osetljiv postupak. Fizičko-hemijska karakterizacija štampanih ploča je od velikog značaja zbog izbora optimalnog postupka za preradu. Cilj ovog istraživanja bila je fizičko-hemijska karakterizacija ploča kao i izdvojenih frakcija nakon sečenja na šrederu i magnetne separacije. Izdvojene frakcije (metalni granulat, magnetna frakcija i plastika) su rastvarane u tri uzastopne faze, luženjem, uz korišćenje: sumporne kiseline, azotne kiseline i carske vode. Eksperimenti su izvedeni na frakcijama dobijenim preradom 100 kg uzorka i upoređivani su sa rezultatima dobijenim hemijskom analizom uzorka dobijenog ručnim rasklapanjem 10 ploča. Takođe, određivan je granulo sastav svake izdvojene frakcije.

AB  - This paper presents original software, developed for the needs of mathematical modeling of complex processes using the simplex method. The software was developed in the Delphi programming language for the Windows environment. The idea was to use the developed software to determine the efficiency of the simplex method in choosing the optimal mode of heat treatment of PdNi5 alloy, and simplex triangle can visually monitor the legality of the behavior of the test process depending on the influential parameters.
AB  - U radu je predstavljen originalni softver, razvijen za potrebe matematičkog modeliranja složenih procesa primenom simpleks metode. Softver je razvijen u programskom jeziku Delphi za Vindovs okruženje. Ideja je bila da se razvijenim softverom utvrdi efikasnost simpleks metode u izboru optimalnog načina termičke obrade legure PdNi5, a simpleks trouglom se može vizuelno pratiti zakonitost ponašanja procesa ispitivanja u zavisnosti od uticajnih parametara.
