▎ 摘　　要

NOVELTY - Method for purifying three-dimensional graphene-coated single-particle nanodiamond material involves magnetically separating raw mixture, acidifying, oxidizing, alkalizing, carrying out re-liquid separation and extracting. USE - Method for purifying three-dimensional graphene-coated single-particle nanodiamond material (claimed). ADVANTAGE - The method efficiently and economically provides purified three-dimensional graphene-coated single-particle nanodiamond material with reduced acidity or alkalinity at room temperature, by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for apparatus for purifying three-dimensional graphene-coated single-particle nanodiamond material.
