Eco-friendly moxifloxacin removal using date seed waste and Ni-Fe LDH: Adsorption efficiency and antimicrobial potential.

BACKGROUND

New pharmacological remediation techniques were needed due to their detrimental impacts on human health and aquatic ecosystems. Layer double hydroxide (LDH) can be made inexpensively and readily available using easy preparation techniques. Three nanomaterials date seed powder (DSP), Ni-Fe LDH, and Ni-Fe LDH/(DSP) composite are used to eliminate Moxifloxacin (MOX).

OBJECTIVE

Providing the date seed powder (DSP), Ni-Fe LDH, and Ni-Fe LDH/(DSP) composite multifunction as an ecofriendly adsorbents for antibiotic residues also its assessing antibacterial effectiveness in addition to other fungal organisms.

METHODS

The catalysts were synthesized via co-precipitation and characterized using HRTEM, FESEM, FT-IR, X-ray, PZC and BET analyses. Adsorption experiments were conducted to evaluate the effects of pH, adsorbent dose, and contact time, while kinetic and isotherm models were employed to elucidate the adsorption mechanisms. Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC), Minimum Bactericidal Concentration (MBC), and Disc Diffusion assays for bacterial activity were applied for antifungal study.

RESULTS

The removal percent of the MOX was 35.37 % at pH 3, 44.91 % at pH 7, and 83.50 % at pH 5 for (DSP), Ni-Fe LDH and Ni-Fe LDH /(DSP) composite, respectively. The Langmuir- Freundlich model is the best suitable model for three nanomaterials (DSP), Ni-Fe LDH and Ni-Fe LDH /(DSP), R2 were (0.97,0.99 and 0.99, respectively) and qmax were (212.77, 206.7 and 251,6 respectively).

CONCLUSION

current research indicates that the Ni-Fe LDH/(DSP) composite is a promising nanomaterial for treating wastewater and has a greater antimicrobial efficacy than each alone against both bacterial and fungal pathogens.
