“…In this study, a porous bubbler was used for the absorption of NO 2 in the solution. However, some researchers have suggested using scrubber or packed column for simulation and determination of maximum absorption (28)(29)(30). The initial amount of absorption was high, because the measuring time started 7 minutes after the start of the system.…”

Background: One of the important achievements of the past decade was the rapid growth of industries and accordingly production of various chemical compounds.Objectives: This study presents a combined system of photocatalytic oxidation and absorption solution to remove nitrogen oxides from polluted air flow. Materials and Methods:The experimental system used in this study comprised a pollutant gas source, mixing chamber, photocatalytic oxidation reactor, wet absorption system, and finally a system for measuring nitrogen oxides. Firstly, by using photocatalytic property, nitrogen oxide was converted to nitrogen dioxide. Then, absorption system was used to absorb nitrogen dioxide into the sodium hydroxide solution. Results: Experimental results have shown that output of nitrogen oxide removal in the initial concentration of 200 ppm was 44% in the beginning of the process and then fixed at 15% during the rest of the process. Also, by changing the amount of zinc oxide nanoparticles from 4 to 8 mg/cm 2 , no considerable change was observed in the conversion rate of nitrogen oxide. In addition, while
