Preparing graphene nano-powder comprises e.g. heating expandable graphite to obtain graphite worms, mixing with swelling solvent, dispersing, swelling to obtain graphene suspension and drying.

ZHANG Y, DENG C

Preparation of graphene used for, e.g. integrated circuits by dispersing graphite in intercalation agent organic solvent, pre-sonicating, heating, cooling, stripping, dispersing into organic solvent, sonicating, and centrifuging.

Preparation of adsorbent for adsorbing heavy metal ions from wastewater, involves adding modified graphene oxide to water and ultrasonically-dispersing and obtaining graphene oxide suspension, and then adding nano zero valent iron.

ZHANG Y

Preparation of graphene oxide as carrier wrapped with nano zero valent iron for e.g. adsorption involves grinding weighed ferrous sulfate and sodium borohydride into mortar to obtain solid phase medium, reacting, dispersing, and drying.
