Abstract
Strontium doped zirconium oxide (SZO) nano particles were synthesized by a hydrothermal particle growth technique and were employed for removal of Cu (II) from water. The synthesized nano adsorbents were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS) and UV-visible spectral studies. The adsorption experiments were affected in batch to establish the influence of pH, contact duration/time, temperature and initial metal ion concentration on adsorption efficiency. This work demonstrates the success of employing SZO nano adsorbents towards efficient removal of Cu (II) from water.

Summary
The substantial increase of toxic heavy metal ion discharge has imposed the scientific community to design novel eco-friendly strategies of heavy metal ion treatment through various physicochemical methods, owing to its hazardous effects on environmental biota. The burgeoning sources of heavier metallic ions in potential water bodies encompass metal ions from fertilizers, chemical fungicides and metallic residues from paint pigment industries [1] These heavy metal ions are known to effect the survival, when followed inappropriate disposal techniques. The electron rich oxygen centres affect efficient removal of heavy metal ions from their solutions through surface adsorption of heavy metal ions on nano ceramic adsorbents [9,10,11,12,13,14,15]. The partial solubilities of metal oxide nano ceramic during adsorption studies may lead to toxic effects, Cu (II) solutions are made to encounter a dual filtration technique wherein, the nano particle treated Cu(II) solutions are passed through charcoal which owing to its high porosity affects Cu(II) coated SZO nano particle entrapment leading to enhanced heavy metal ion amputation. The effects of hydronium ion content (pH), contact time and temperature on adsorption kinetics have been established
