A novel hybrid based on oxidized multiwalled-carbon nanotubes (ox-MWCNTs) and stannic-molybdophosphate (SMP) were synthesized and used accompanied by its pristine materials to investigate strontium removal from aqueous solution. These materials were characterized by transmission electron microscopy, nitrogen adsorption/desorption isotherms, Fourier-transform infrared spectroscopy, thermogravimetry and X-ray diffraction analysis. Strontium adsorption on the ox-MWCNTs, SMP and hybrid as a function of initial strontium concentration, contact time, adsorbents dosage, pH and ionic strength was studied. The prepared hybrid showed the highest adsorption capacities for strontium which suggests that it can be a promising adsorbent for strontium removal from nuclear waste.
