237Np(Ⅴ)is estimated to be the most hazardous radionuclide concerning its half-time(2.14×106year),radiotoxicity and environmental behavior.It has been reported that most of actinides can be sequestered by a variety of minerals,especially iron oxides as common components of rocks,soils and sediments.Np(Ⅴ)sorption at mineral-water interfaces are of great importance in contaminant regulation
