This article has been retracted at the request of the Editor-in-Chief. Spectrum “pH 7.5” from Fig. 6 appears similar to spectrum “T = 323.15 K” from Fig. 7 of the article. Also, Fig. 2B appears similar to Fig. 2 of the article that some of the authors have previously published in the Chemical Engineering Journal 168 (2011) 178–182 https://doi.org/10.1016/j.cej.2010.12.060. Text from Introduction has been reused from the article that was previously published by Castaldi et al. in the Journal of Hazardous Materials 156 (2008) 428–434, https://doi.org/10.1016/j.jhazmat.2007.12.040, Encyclopaedia Britannica https://www.britannica.com/science/mordenite and the article from the Chemical Engineering Journal. https://doi.org/10.1016/j.cej.2010.12.060.
