Description The present report deals with the synthesis, characterization and testing of an
ethyl cellulose–calcium(II) hydrogen phosphate (EC–CaHPO4) composite,
where a sol–gel synthesis method was applied for the preparation of the
composite so as to test its efficacy towards the electrochemical, biological, and
adsorption related applications. The physical properties of the composite were
characterized by using scanning electron microscopy (SEM), ultraviolet–
visible (UV–Vis) spectroscopy, and fourier transform-infrared (FTIR) spectroscopy.
On testing, the mechanical properties indicated that the composite is
highly stable due to the cross-linked rigid framework and the enhanced
interactions offered by the EC polymer supported for its binding very effectively.
In addition, the conductivity of EC–CaHPO4 is completely governed by
the transport mechanism where the electrolyte concentration has preference
towards the adsorption of ions and the variations in the conductivity significantly
affected the material’s performance. We observed an increasing order of
KCl> NaCl for the conductivity when 1:1 electrolytes were applied. Further,
the material was tested for its usefulness towards the purification of industrial
waste waters by removing harmful metal ions from the samples collected near
the Aligarh city, India where the data indicates that the material has highest
affinity towards Pb2+, Cu2+, Ni2+ and Fe3+ metal ions. Finally, the biological
efficiency of the material was confirmed by means of testing the antibacterial
activity against two gram positive (staphylococcus aureus and Bacillus thuringiensis)
and two gram negative bacteriums (Pseudomonas aeruginosa and
Patoea dispersa). Thus, from the cumulative study of outcomes, it indicates
that the EC–CaHPO4 composite found to serve as a potential smart biomaterial
due to its efficiency in many different applications that includes the
electrical conductivity, adsorption capability, and antimicrobial activity.
