Sažetak
Nowadays, accessible clean water and energy resources are among the highest priorities for sustainable economic growth and societal wellbeing. Water scarcity is an increasing problem globally making it imperative that wastewater is treated and reused in industrial processes, for irrigation and feeding to livestock, thus saving potable water for drinking. Up till now, semiconductor catalysts are produced in the form of a powder suspended in a model solution of pollutants. Many reactors use catalysts in form of suspension where the separation and reuse of the catalyst are difficult to achieve with significant catalyst loss, efficiency, and cost-effectiveness of the process. Regarding the practical applications, immobilised catalysts are more favorable due to the continuous mode of operation and multiple times usage. Reactive orange 16 (RO- 16) is a well-known azo-dye in the environment that is not removed during wastewater treatment because of its high persistence in the aquatic solution. The aim of this work is to evaluate the removal of RO-16 using the surfacefunctionalised polyacrylonitrile (PAN) mesh with Fe (III). The catalyst was tested in a reactor in batch mode at a laboratory scale at different catalytic parameters. The removal of RO-16 was detected by measuring the absorbance at 254 nm and 493 nm by UV-Vis spectrophotometer. Removal of 50 mg/L of RO-16 was achieved under UV-C radiation using 125 mg/L H2O2, 6 g PAN catalyst, 25 °C, and pH 3. After five cycles of use, there was no significant difference in the activity of the catalyst.
