摘要： Iron is the first abundant transition metal in the earth's crust. Meanwhile, copper is an essential trace element that can affect the reductive reactivity of sorbed Fe(II) species through Fe(II)/Cu(II) interaction. This study aims to elucidate the impact of the Fe(II)/Cu(II) interaction in 2-nitrophenol (2-NP) reductive transformation on kaolin, TiO2, and alpha-FeOOH. Kinetic measurements demonstrated that 2-NP reduction rates (k) by sorbed Fe(II) species can be promoted by adding Cu(II), whereas the impact of the Fe(II)/Cu(II) interaction on different minerals differed significantly with the k values. The increasing trend in the k values (kaolin TiO2/GC > alpha-FeOOH/GC), as well as with the increasing trend in the normalized sorbed Fe(II) density (kaolin
