Abstract
U ovom radu ispitivana je mogućnosti recikliranja iskorištenog papira s eko lužinom dobivenom od pepela. Korištena lužina, nazvana eko lužina, dobivena je otpadnog pepela u kućanstvu nastalim sagorijevanjem ogrjevnog drveta bukve i hrasta. Uzorci papira korišteni za reciklaciju deinking flotacijom uzeti su iz dnevnih novina, točnije Večernjeg lista. Postupak kojim se vršilo uklanjanje bojila iz uzorka navedenih tiskovina proveden je po uzoru na Ingede Metodu11, gdje se uz površinsko aktivnu tvar (potrebnu za proces flotacije) od kemikalija za deinking koristila jedino eko lužina. Kao kontrolni postupak na istim uzorcima tiskovina proveden je i klasičan flotacijski deinking sa svim definiranim kemikalijama, poznat kao Ingede Metoda 11. Tijekom flotacijskog deinkinga uz klasične kemikalije (korištene u Ingede Metodi 11) i uz eko lužinu formirani su laboratorijski listovi prije i nakon flotacije. Kako bi se ustanovilo je li laboratorijski pripremljena eko lužina pogodna za flotacijski deinking, točnije uklanjanje bojila, provedena su optička ispitivanja na laboratorijskim listovima formiranim prije i nakon flotacije. Od optičkih svojstava ispitivana je prozirnost, svjetlina i količina zaostale tinte u uzorku (ERIC). Također je vršena i slikovna analiza pomoću Spec*Scan 2000 (Apogee Systems Inc.) te je dobivena ukupna površina čestica, ukupan broj čestica, te klasifikacija detektiranih čestica u 25 klasa veličina. Uspoređivanjem dobivenih vrijednosti na laboratorijskim listovima formiranim nakon obrade eko lužinom u flotacijskom deinkingu i klasičnim deinking kemikalijama (Ingede Metoda 11) može se zaključiti da postoji mogućnost korištenja eko lužine u procesu uklanjanja bojila iz iskorištenog papira.
Abstract (english)
This study overhauls the possibility of recycling of used paper with eco alcali obtained from ashes. Used lye, called eco alkali, was produced from combustion waste obtained in households from burning beech and oak. Paper samples used for deinking flotation were taken from croatian daily news paper named Večernji list. The procedure which was done to remove dye from samples was conducted according to model Ingede Methode 11, where the sufracant (necessary for deinking flotation) was only used eco alkaly. As a control procedure on the same samples was conducted classical deinkig flotation with all defined chemicals known as Ingede Methode 11. During flotation deinking with classical chemicals, and with eco alkali laboratory sheets were formed before and after flotation. The reason for doing this was determination whether eko alkaly is suitable for deinking flotation, namely the removal of dyes, optical tests were conducted on laboratory sheets formed before and after flotation. Optical properties that were tested are transpareny, brightness, and amount of residual ink (ERIC). Image analysis was conducted with Spec*Scan 2000 (Apogee Systems Inc.), which gained total particle area, total particle number, and it classified detected particles in 25 sizes. After comparasion of gained values on laboratory sheets formed after deinking flotation with eco alkaly and classical chemicals it can be concluded that eco alkaly can be suitable for dye removal from used paper.
