The current study involves a synthesis of composite nickel oxide nanoparticles (NiONPs) with chromium dopant to yield (Cr/NiONPs). Synthesis was performed by the co-precipitation method. conducted impregnation FTIR, EDX, SEM, and XRD were used characterize synthesized materials. synthesised materials' point zero charges (PZC) using potentiometric titration obtained results show that PZC for neat around 5, it 8 Cr/NiONPs. adsorption action prepared materials examined applying them remove Reactive Red 2 (RR2) Crystal Violate (CV) dyes from solutions. outcomes demonstrated Cr/NiONPs stronger in removal than NiONPs. achieved 99.9% after 1 h. Adsorption isotherms involving Freundlich Langmuir also conducted, indicated most accurate representation data offered isotherms. Additionally, discovered characteristics NiONPs correspond well pseudo-second-order kinetic model. Each reused five times, display effectiveness RR2 dye slightly declined increase reuse cycles; lost only 5% its original efficiency 5 cycles. Generally, showed better reusability under same conditions.
