Abstract

In this study, removal rates of phenol and lignin, which are toxic impurities, in wastewaters of paper industry and the changes in turbidity of wastewater were investigated. In the experiments, perlite minerals activated at 105°C were used as an adsorbent. Adsorption time, particle size, temperature, solid/liquid ratio and pH were taken as experimental parameters. As a result of the experimental studies, we found that lower pH, 0.02 g/ml of solid/liquid ratio, an hour of adsorption time and 35°C of adsorption temperature are the optimum conditions for efficient removal of lignin and phenol. Using these conditions, while the removal percentage of phenol and lignin were 59% and 46%, respectively, turbidity value decreased from 79.6 mg/1 to 23.5 mg/1.

Özet

Bu çalışmada, adsorpsiyon yöntemini kullanarak, kağıt endüstrisi atık sularında kirliliğe ve zehirliliğe neden olan fenolik ve lignin bileşiklerinin giderim oranlar ile atık suyun türbidite (bulanıklık) değerlerindeki değişimler incelendi. Deneylerde adsorbent olarak 105°C'de aktive edilmiş perlit minerali kullanıldı. Adsorpsiyon süresi, tane boyutu, sıcaklık, katı/sıvı oranı ve pH'nın etkisi parametre olarak seçildi. Deneyler sonucunda, düşük pH, 0,02 g/ml katı/sıvı oranı, bir saatlik süre ve 35°C adsorpsiyon sıcaklığı optimum giderim için uygun bulundu. Bu şartlarda, fenolde %59, ligninde %46 oranında giderim sağlanırken türbiditenin (bulanıklık) 79,6 mg/T den 23,5 mg/l'ye düştüğü görüldü.
