In recent years, the excessive use and improper disposal of antibiotics have led to their pervasive presence in environment, resulting significant antibiotic pollution. To address this pressing issue, present study synthesized nickel–iron-layered double hydroxides (NiFe-LDHs) with varying molar ratios using a hydrothermal method, employing these LDHs as catalysts for oxidative degradation doxycycline, peroxymonosulfate (PMS) serving oxidant. X-ray diffraction analysis confirmed that NiFe-LDHs exhibited hexagonal crystal structure characteristic layered hydroxides. Experimental results demonstrated catalytic efficiency increased both dosage catalyst concentration PMS, achieving high doxycycline at 0.5 g/L. Furthermore, performance was notably effective across range pH conditions, highest being observed Ni–Fe ratio 3:1. The activation PMS by pollutants primarily occurs through singlet oxygen (1O2), superoxide radicals (O2−·), sulfate (SO4−·). also proposed three potential pathways indicating final products lower environmental toxicity. This research offers novel approaches methodologies treatment antibiotic-contaminated wastewater.
