Abstract
Vanadiumoxide nanoparticles (VO2-NPs) were synthesized and utilized as an adsorbent against methylene blue (MB) fromaqueous environment. Three substantial variables, pH, mixing time, and VO2 dose,were considered in the process modeling accomplished by Box-Behnken design (BBD). The quadratic model revealed that the VO2- NPs dose plays the most significant role. The model optimization predicts a 96.3%MB removal when pH, VO2 NPs dosage, and contact time were adjusted to 6, 0.5 g/L, and 30 min, respectively. The sorption capacity of VO2-NPs raised rapidly from 49.6 mg/g to 235.7 mg/g by increasing the initial MB concentration from 25 to 200 mg/L, respectively. The best fitted kinetic model was the pseudo-second order, while the well fitted Langmuir model showed a qmax of 240.5 mg/g. The study of the temperature effect revealed that increase of the temperature had a positive impact on the removal efficiency.
