摘要: A sol–gel process followed by a calcination treatment was employed to synthesize magnetic Ni/NiO nanoparticles. The as-formed particles were characterized using XRD, TEM, UV–vis, surface area and VSM. XRD results show that the patterns of product synthesized 1:1, 1:2, 1:3 molar ratio nickel nitrate/citric acid composed mixture NiO Ni, whereas recorded for 2:1 3:1 exhibited single phase. All prepared samples are in form nanoparticles with sizes locate range 33 up 118 nm different ratios. photocatalytic tests conducted degradation EDTA. EDTA removal efficiency is 99.9% at 3 × 10−3 M concentration. reaction follows first order kinetics respect rate constants t1/2 0.4 g/l catalyst/EDTA solution were, respectively 460 min−1, 15.1 min.
