▎ 摘　　要

NOVELTY - Method for preparing graphene scale inhibition filter element, involves (a) preparing modified graphene composite powder, (b) preparing graphene activated carbon composite particles, and (c) preparing graphene activated carbon composite scale inhibition filter element. USE - The method is used for preparing graphene scale inhibition filter element (claimed). ADVANTAGE - The filter element has high-efficiency and excellent scale inhibition effect, effectively removes the calcium and magnesium ions in water, does not release harmful ions to human body, completely adsorbs the small molecule organic substances, bacteria, different colors and odors in water, reduces the scale formation, prolongs long-term life, and the water quality is sweet and delicious.
