Abstract

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 q_max 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.

红枣渣和Ni-Fe LDH环保型去除莫西沙星：吸附效率和抗菌潜力

背景由于对人类健康和水生生态系统的有害影响，需要新的药物修复技术。层状双氢氧化物（LDH）可以用简单的制备技术制备，成本低且容易获得。采用三种纳米材料枣籽粉（DSP）、Ni-Fe LDH和Ni-Fe LDH/(DSP)复合材料去除莫西沙星（MOX）。目的研究红枣籽粉（DSP）、Ni-Fe LDH和Ni-Fe LDH/ DSP复合复合材料对抗生素残留的生态吸附剂性能，并评价其对其他真菌的抗菌效果。方法采用共沉淀法合成催化剂，并采用HRTEM、FESEM、FT-IR、x射线、PZC和BET分析对催化剂进行表征。通过吸附实验考察了pH、吸附剂剂量和接触时间对吸附的影响，并采用动力学模型和等温模型分析了吸附机理。采用最小抑菌浓度（MIC）、最小杀真菌浓度（MFC）、最小杀菌浓度（MBC）和圆盘扩散法测定细菌活性。结果（DSP）、Ni-Fe LDH和Ni-Fe LDH /(DSP)复合材料在pH 3、pH 7和pH 5下对MOX的去除率分别为35.37 %、44.91 %和83.50 %。Langmuir- Freundlich模型是三种纳米材料（DSP）， Ni-Fe LDH和Ni-Fe LDH /(DSP)的最适合模型，R2分别为（0.97,0.99和0.99），qmax分别为（212.77,206.7和255.1）。结论Ni-Fe LDH/(DSP)复合材料是一种很有前途的污水处理纳米材料，其对细菌和真菌病原体的抗菌效果都优于单独使用Ni-Fe LDH/(DSP)复合材料。
