SYNTHESIS OF ZEOLITE A FROM KAOLIN LOADED WITH CARBON NANOTUBES AND THE EVALUATION OF ITS ANTIMICROBIAL ACTIVITY
Authors: *Kovo A.S, Dyil P, Ali A.F.
This study evaluates the antimicrobial activity of zeolite A loaded with Carbon Nanotubes (CNTs) against bacterial isolates usually common in water (especially wastewater). The zeolite was synthesised using the hydrothermal synthesis method while incorporation of CNTs into it was via the sol gel method. The sample was characterised using X-ray Diffraction (XRD) Fourier Transform Infrared spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM). The results showed well-defined cubic crystals of Zeolite A were formed and confirms the homogeneous distribution of CNT around them. The antimicrobial activity of Zeolite A/CNT was tested against three gram-negative bacteria (Salmonella typhi, Escherichia coli and Pseudomonas Aaeruginosa), using the agar dilution method at concentrations of 12, 16 and 20 mg/ml. Results showed no significant activity irrespective of the concentration. Only delayed growth was noticed in P. aeruginosa.
