Functionalized halloysite nanotubes with amine dendrimer for the adsorption of acidic dye from textile wastewater

Halloysite nanotubes (HNTs) are one of the mineral adsorbents using for the removal of dyes from effluents. The capability of the functionalized HNYs with amine terminated group dendrimer has been developed for acidic dye adsorption (Methyl orange). This process was studied using FTIR spectra which indicated that the amino group set on the HNTs structure help to increase the capacity of acidic dye adsorption from 7% to 60% by the electrostatic interaction, and the generation of the synthesized hyperbranched polymer helps to increase the rate of dye removal due to the existence of more adsorption sites on the dendritic structure via more exterior amine group at the surface
