Microwave-assisted hydrothermal synthesis and adsorption properties of carbon nanofibers for methamphetamine removal from aqueous solution using a response surface methodology

Carbon nanofibers have been synthesized by simple facile microwave-assisted hydrothermal route and applied as adsorbent for the fast adsorption of methamphetamine. The topological property of CNF was analyzed using XRD, SEM, TEM, and nitrogen adsorption-desorption instrumental techniques. The significance of the independent variables and their interactions were tested by the analysis of variance (ANOVA) and t-test statistics. Influential parameters are optimized using BBD implemented with RSM, and the optimized value of pH, adsorbent dose and temperature was found to be 8.0, 0.1 g and 298 K, respectively. Under optimal conditions, the removal efficiency of methamphetamine was found to be 55.25 mg/g. (C) 2016 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
