(1)1-(2-pyridinazo)-2-naphthol (PAN) was used to form a complex with metal ions,and then reacted with the solution of Fe3+ and Fe2+ with concentration ratio 1∶2 to form Fe3O4-PAN-Mn+;(2)With hydrazine hydrate as a reducing agent,metal ions was reduced to form Fe3O4-PAN-M0,which was enriched and separated from the system by magnets,simplifying the separation process.The product was expected to be further used in monitoring of organic small molecules in the environmental system.
