“…Therefore, in our previous work on the dye adsorption, [27][28][29][30][31][32][33], the purpose of this research is the synthesis and characterization of boehmite (-AlOOH) nanoplatelets and nanowires modified with sulfonic acid and the comparison between these two structures in adsorption of anionic dye in different conditions such as contact time, pH, initial anionic dye concentration and temperature. Adsorption kinetics, isothermic and thermodynamic models were considered to obtain the parameters to describe the anionic dye adsorption processes.…”

a b s t r a c tIn this study, boehmite (-AlOOH) nanoplatelets and nanowires were synthesized at a pH of 5 and 12, respectively, modified with sulfonic acid (-AlOOH-SA5), (-AlOOH-SA12), and were used to adsorb eriochrome black T (EbT) dye solutions. Transmission electron microscopy, scanning electron microscopy, Fourier-transform infrared spectroscopy and X-ray diffraction were used to characterize the prepared nanoplatelets and nano wires. The effect of many parameters including initial concentration, pH and contact time was investigated. Values of 212.76 and 116.28 mg g -1 were, respectively, obtained for AlOOH-SA5 and AlOOH-SA12 for the adsorption maximum of EbT. Compared between two structures, the results indicated that the optimum conditions for 100 mg L -1 EbT solution were pH of 3 and 0.5 g L -1 AlOOH-SA5 as well as pH of 3 and 1 g L -1 AlOOH-SA12. Results of adsorption isotherms and adsorption kinetics indicated which they better matched by the Langmuir isotherm and also the adsorption kinetics better described by the pseudo-second-order model. Thermodynamic parameters have been measured, and results indicate that the adsorption process was spontaneous and exothermic for AlOOH-SA12 and nonspontaneous and endothermic for AlOOH-SA5. Finally, AlOOH-SA5 is a suitable adsorbent than that of AlOOH-SA12 and can be used for dye removal in wastewater treatment processes.

In this research, we synthesized and characterized a new heterogeneous basic nanocatalyst and its catalytic application was studied in the Claisen‐Schmidt and Knoevenagel condensations. In order to prepare this nanocatalyst, first, the Iranian natural asphalt was sulfonated with the concentrated sulfuric acid and then, converted to the potassium natural asphalt sulfonate (K‐NAS). In order to characterization of the nanocatalyst, used of FT‐IR spectroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X‐ray diffraction (XRD), inductively coupled plasma (ICP) and thermogravimetric analysis (TGA) techniques. This new basic heterogeneous nanocatalyst have advantages such as being eco‐friendly, huge specific surface area, high reactivity and recyclability.
