Central composite design (CCD) model has shown good fittings of the coefficient of determination (R2) with non-significant lack of fit for both UiO-66(Zr) and NH2-UiO-66(Zr) MOFs. The optimized adsorption efficiency achieved by the UiO-66(Zr) and NH2-UiO-66(Zr) were 99.22 and 95.67 respectively. Artificial neural network (ANN) model was able to predict the experimental findings with high precision at topographic node of 5-4-2 structural layer. The kinetics and isotherms of the process was best described by pseudo-second-order Langmuir models respectively. The process was exothermic and spontaneous with the good reusability of the MOFs. {\^A}{\copyright} 2020 Elsevier Ltd}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85093927924&doi=10.1016\%2fj.poly.2020.114857&partnerID=40&md5=a4d4aa27d3698cae58328dbed8eadaee}, issn = {02775387}, author = {Zango, Z.
