▎ 摘　　要

NOVELTY - Graphene soil modifier comprises 40-60 pts. wt. biomass fertilizer, 10-12 pts. wt. microbial agents, 7-9 pts. wt. grapheme, 3-5 pts. wt. bentonite, 1-3 pts. wt. humic acid, 2-4 pts. wt. bagasse charcoal, 0.8-1.8 pts. wt. chelating agent, 1-3 pts. wt. activated carbon, and 1-3 pts. wt. carbon nanotubes. USE - Used as graphene soil modifier. ADVANTAGE - The graphene soil modifier has good adsorption effect on heavy metal ions in soil during application process, and larger adsorption capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene soil modifier, comprising (i) preparing materials and measuring raw materials, (ii) conveying biomass fertilizer, humic acid, bagasse charcoal and bentonite to high-speed mixer for stirring, stirring speed 1100-1200 revolutions/minute, stirring for 35-45 minutes to obtain mixture A, (iii) conveying microbial agent into fermentation tank, maintaining internal temperature of ferment at 45-55 degrees C, stirring every 14-18 hours, and completing fermentation to obtain mixture B, and (iv) adding mixture A and mixture B, graphene, activated carbon, carbon nanotubes, and chelating agent to high-speed mixer, rotating at 900-1000 revolutions/minute, stirring for 1-2 hours, conveying mixture into dryer, drying at 50-60 degrees C, and conveying it into granulator to granulate to obtain graphene soil modifier. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of is process flow diagram of graphene soil modifier. (Drawing includes non-English language text)
