Abstract
Pripremljeni su uzorci biougljena karbonizacijom ljuski pistacija pri tri različite temperature (350°C, 450°C i 550°C). Na pripremljenim uzorcima biougljena provedena je djelomična analiza s ciljem određivanja udjela vlage, pepela te isparljive i stalne tvari te su ispitana njihova adsorpcijska svojstva. Porast temperature je doveo do smanjenja prinosa na uzorcima biougljena te je sukladno tome najmanji prinos na uzorku biougljena pripremljenom pri temperaturi karbonizacije od 550°C. Također,... More udio isparljivih tvari se smanjuje s porastom temperature. Sadržaj stalne tvari raste s porastom temperature karbonizacije, kao i udio pepela i vlage. Najzastupljenije čestice su one koje pripadaju frakciji 90-100 µm kod svih pripremljenih uzoraka biougljena. U uzorcima biougljena pripremljenim pri dvije više temperature (450°C i 550°C) uočavaju se sitne svjetlije čestice koje bi mogle pripadati ostatcima sagorene organske tvari. Količina adsorbiranih bakrovih iona, kao i učinak adsorpcije rastu porastom temperature pri kojoj je pripremljen biougljen. Less
Abstract (english)
Biochar samples were prepared by carbonizing pistachio shells at three different temperatures (350°C, 450°C and 550°C). Proximate analysis was performed on the prepared biochar samples in order to determine moisture content, ash, and mobile and resident matter, and their adsorption properties were tested as well. The increase in temperature led to a decrease in the yield of the biochar samples and, accordingly, the lowest yield was on the biochar sample prepared at a carbonization... More temperature of 550°C. Also, the content of volatile substances decreases with the temperature increase. The content of resident matter increases with the increase in carbonization temperature, as well as the content of ash and moisture. The most abundant particles fall into the 90-100 µm fraction in all prepared biochar samples. In the biochar samples prepared at two higher temperatures (450°C and 550°C), tiny light-pale particles can be observed, which could be the remains of burned organic matter. The amount of adsorbed copper ions, as well as the adsorption efficiency, increase with the temperature at which the biochar was prepared. Less
