Abstract |
The use of contaminated water by bacteria may cause many diseases, and thus clean water is needed. Chlorine
is normally used for the disinfection of wastewater treatment; however, it produces unwanted odors. Using
extracted Piper betle (P. betle) is an interesting choice because it is a good chemical compound for
bacterial inhibitions. This study attempted to extract P. betle leaf and synthesize P. betle beads (PBB) to
characterize materials and investigate antibacterial efficiencies by disc diffusion assay, batch tests,
adsorption isotherms, kinetics, and material reusability. The results demonstrated the successful extraction
and synthesis of the materials of P. betle. P. betle powder (PBP) had porous and rough surfaces, whereas
PBB had a spherical shape with a coarse surface. The four main chemical elements and functional groups
of PBP and PBB were carbon, oxygen, calcium, chlorine, and O–H, C–H, N–H, C–O, respectively. The
extraction yield and total phenolic, flavonoid, and tannin contents of P. betle were 11.30%, 201.55
0.31 mg GAE per g, 56.86 0.14 mg RE per g, and 41.76 1.32 mg CE per g, respectively. The six main
compounds of eugenol, quercetin, apigenin, kaempferol, ascorbic acid, and hydroxychavicol were detected
by HPLC analysis. The results of the disc diffusion assay confirmed antibacterial efficiencies of PBB, and the
batch tests examined high antibacterial efficiencies of PBB for 100% on Staphylococcus aureus and
Escherichia coli. The adsorption isotherms and kinetics of PBB corresponded to Freundlich model and
pseudo-second order kinetic model, and the desorption experiments confirmed the reusability of PBB.
Therefore, PBB can be possibly applied for an antibacterial purpose in wastewater treatment systems. |
