▎ 摘　　要

NOVELTY - Preparing polysilicon ferromanganese graphene flocculant comprises (i) uniformly mixing silica ash with concentrated sulfuric acid and aging to obtain polysilicate; (ii) adding graphite powder to polysilicic acid, uniformly mixing and aging to obtain graphite polysilicic acid; (iii) uniformly mixing sodium peroxodisulfate and potassium permanganate to obtain mixed oxidant, adding the mixed oxidant to graphite polysilicic acid and mixing, sonicating, and aging to obtain graphene polymanganese silicate; and (iv) uniformly mixing the humic acid, iron powder and graphene oxide polymanganese silicate, age, adjusting the pH to acid, continuously aging, drying, and grinding to obtain polysilicon iron manganese graphene flocculant. USE - The method is useful for preparing polysilicon ferromanganese graphene flocculant. ADVANTAGE - The method is simple and economical; easy to realize; utilizes raw materials, which are widely used; and captures multiple pollutant flocculating recycling efficiency.
