Facile application of OH-ended triazinic dendrimer/halloysite nanotube for removal of methylene blue with a high capacity

In this study, OH-ended triazinic dendritic polymers were constructed and developed on the surface of halloysite nanotubes (HNTG2) to proficiently evacuate methylene blue (MB) from water. The morphology structure nano-absorbent materials decided by TEM (transmission electron microscopy), XRD (X-ray diffraction), FTIR (Fourier transform infrared), TGA (thermogravimetric analysis), isothermal BET (Brunauer Emmet Teller) EDS (energy dispersion analysis X-ray spectroscopy). adsorption MB gives a most extreme 1428.57 mg/g at 298 K an ideal pH 6. As study revealed, kinetics followed pseudo-quadratic model while isotherms sub-corresponding Freundlich model. like manner, it can be induced that takes place heterogeneous further, rate-controlled step known as chemisorption. addition, thermodynamic results also show process occur spontaneously, which is considered endothermic reaction. Interestingly, sorption desorbing productivities after four runs are both high, whereas mechanism affects adsorbent mainly through various types interactions such hydrogen bonding, chemisorption electrostatics interactions. Therefore, concluded HNTG2 effective in eliminating aqueous solution, great applicability importance.
