The need for magnetically separable toxicant-absorbing materials for waste and contamination disposal is vital for environmental decontamination. Humic substances (HS) and their derivatives are an abundant resource and this paper characterizes their properties when combined with iron oxide molecules in a nanocomposite matrix. A mechanochemical technique is described that provides an inexpensive production method for sorbents with the requisite properties for binding chemical and radiochemical contaminants.
