Organic pollutant discharges to water bodies are found to be toxic. A simple chemical co-precipitation method has been adopted for the preparation of Cu–MgFe₂O₄ nanoparticles, because photocatalysts can extract dye pollutants from wastewater. Phase evaluation, microstructure, magnetic and electrical properties were studied. The spinel structure was examined by the X-ray diffractometer (XRD) and the approximate crystalline sizes ranged from 12 to 44 nm. The morphology of the prepared products was documented by the transmission electron microscope (TEM). Magnetic hysteresis (M-H) curves were performed using a vibrating magnetometer sample. The coercive value (Hc) increases while the saturation magnetization (Ms) decreases with the substitution of Cu²⁺. Room temperature DC electrical and AC conductivity tests were carried out for all materials. The antibacterial activity of Cu–MgFe₂O₄ NPs was studied using Agar well diffusion method and the samples MCFO-2 and MCFO-3 NPs showed maximum antibacterial activity compared to MCFO-1 NPs (minimum activity) against Micrococcus luteus (Gram positive) and Escherichia coli (Gram negative). Photo-Fenton operation was performed using organic methylene blue (MB) to analyze the dye removal efficiency of spinel Cu–MgFe₂O₄ nanoparticles.

发现排放到水体的有机污染物是有毒的。由于光催化剂可以从废水中提取染料污染物，因此采用了一种简单的化学共沉淀方法来制备Cu-MgFe ₂ O ₄纳米颗粒。研究了相评价，显微组织，磁和电性能。用X射线衍射仪（XRD）检查尖晶石的结构，晶体的近似尺寸为12-44nm。通过透射电子显微镜（TEM）记录了所制备产品的形态。使用振动磁力计样品执行磁滞（MH）曲线。随着Cu ²⁺的替换，矫顽力值（Hc）增大，而饱和磁化强度（Ms）减小。对所有材料进行了室温直流电和交流电导率测试。使用琼脂井扩散法研究了Cu–MgFe ₂ O ₄ NPs的抗菌活性，与MCFO-1 NPs（最低活性）相比，样品MCFO-2和MCFO-3 NPs具有最大的抗菌活性（革兰氏阳性）。和大肠杆菌（革兰氏阴性）。使用有机亚甲基蓝（MB）进行Photo-Fenton操作，以分析尖晶石Cu–MgFe ₂ O ₄纳米颗粒的染料去除效率。
