| contents | Optimization for benzeneacetic acid removal from aqueous solution using CaO2 nanoparticles based on Taguchi method Sapana S. Madan Kailas L. Wasewar Ingeniería adsorption nanoparticles Taguchi method calcium peroxide benzeneacetic acid Nanoparticles of CaO2were synthesized by chemical precipitation method and characterized by X-ray powder diffraction (XRD), scanningelectron microscope (HR-FESEM), energy-dispersive X-ray spectroscopy (EDX), transmittance electron microscopy (TEM) and high-resolutionTEM (HRTEM). HR-FESEM, TEM, and HRTEM images confirmed the average size of nanoparticles as 10–40 nm. Furthermore, application ofsynthesized CaO2nanoparticles for the removal of benzeneacetic acid was studied by the Taguchi method. The operating parameters are CaO2nanoparticles dosage (0.008–0.03 g), initial concentration of benzeneacetic acid (6.8–13.47 g/L), and contact time (5–60 min). The result indicatesthat the CaO2nanoparticles adsorbent dosage was the most effective factors as compared to initial concentration of benzeneacetic acid and contacttime. The optimum parameters were CaO2nanoparticles adsorbent dosage = 0.03 g, initial concentration of benzeneacetic acid = 6.8 g/L, contacttime = 30 min, and the removal efficiency of benzeneacetic acid = 94.49%. ANOVA showed the most significant factors were adsorbent dosagewith 93.78% contribution. Regression analysis (R2= 0.91) showed a good agreement between the experimental and the predicted values. 2017 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47452572003 https://www.redalyc.org/journal/474/47452572003/ https://www.redalyc.org/journal/474/47452572003/html/ https://www.redalyc.org/journal/474/47452572003/47452572003.epub https://www.redalyc.org/journal/474/47452572003/movil en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.4 Vol.15 |
