Removal of noxious Cr (VI) ions using single-walled carbon nanotubes and multi-walled carbon nanotubes

Microporous nanocrystalline NaA zeolite prepared by microwave assisted hydrothermal method and determination of kinetic, isotherm and thermodynamic parameters of the batch sorption of Ni (II)

“…There are several adsorbents such as sensors and electrochemical electrodes [14][15][16][17][18], bagasse fly ash [19,20], bottom ash [21,22], CNTs and MWCNTs [23][24][25][26][27][28][29][30], fix bed adsorbers [31], resins [32], nanoparticles [33][34][35][36][37][38][39], and rubber tire [40][41][42], these all and the previously developed adsorbents have various applications in many scientific and industrial fields, including wastewater purification, heavy metal ion removal and hazardous impurities.…”

Removal of linear alkyl benzene sulfonate from aqueous solutions by functionalized multi-walled carbon nanotubes

“…CNTs, in particular, received special attention for potential application in environmental protection and to work effectively against chemical and biological contaminants [15,18,21]. Single and multiwalled carbon nanotubes (MWCNTs) have been used in water and wastewater treatment [15].…”

Sulfonated poly(arylene ether nitrile)/polypyrrole core/shell nanofibrous mat: an efficient absorbent for the removal of hexavalent chromium from aqueous solution

“…Typically, the removal efficiency is strongly dependent on the intrinsic properties and surface active sites of adsorbents. Therefore, many carbon based smart nano‐materials such as carbon nanotubes, graphene and graphene derivatives exhibit excellent adsorption performance for hexavalent chromium and other heavy metal ions . Although many achievements have been made, there are still some drawbacks for practical applications.…”
