Abidin Ong, Soon An Fahmi, Muhammad Ridwan Abdul Haqi, Ibrahim S. N. Sabri S. H. Kow S. A. Malik drfahmi@unimap.edu.my Ozonation (O₃) Azo dye Persulfate (Na₂S₂O₈) 2D and 3D Contour Plot ANOVA Link to publisher's homepage at http://amci.unimap.edu.my Advanced oxidation processes (AOPs) especially ozonation method is widely studied in the wastewater treatment field. In this study, it highlighted about three main environmental issues in the world such as 1) proposing a method to overcome uncontrollable effluents from textile industries by using synthetic dyes; 2) creating an improvement of previous conventional method; 3) reduced process time by using statistical approach. To address with this issue, analysis of variance (ANOVA) from Response Surface Methodology (RSM) to study the performance of O3 with the help of persulfate (Na₂S₂O₈) for treating one of azo dyes which is Reactive Green 19. This is due to there is very limited work done by statistical analysis on this study. Hence, ANOVA data would propose statistical models tailored to the data in 2D and 3D contour plots by knowing the three influenced parameters which is pH (6 to 10), persulfate concentration (30 to 70 mM) and contact time (4 to 20 min). Through the analysis, the result can be concluded that improvement of ozonation process with persulfate (Na₂S₂O₈) were statistically significant after all interactive effects gave a positive feedback towards responses. The obtained optimum conditions included a persulfate concentration (49 mM), initial pH (8.89) and contact time (18 min) with fixed initial concentration 100mg/L. The experimental results were corresponded well with predicted models colour removal rates which is 99%. 2018-07-24T02:07:28Z 2018-07-24T02:07:28Z 2018 Article Applied Mathematics and Computational Intelligence (AMCI), vol.7(1), 2018, pages 47-58 2289-1323 (online) 2289-1315 (print) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/54444 en Institute of Engineering Mathematics, Universiti Malaysia Perlis |
