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.
