▎ 摘 要
NOVELTY - Preparation of dithiocarbamate chelating agent-modified graphene oxide involves carboxylating graphene oxide, and modifying the resultant carboxylated graphene oxide using R-dithiocarbamic acid (I). USE - Preparation of dithiocarbamate chelating agent-modified graphene oxide used in adsorption of heavy metal. ADVANTAGE - The method provides dithiocarbamate chelating agent-modified graphene oxide having excellent recyclability and adsorption efficiency with respect to heavy metals. DETAILED DESCRIPTION - Preparation of dithiocarbamate chelating agent-modified graphene oxide involves carboxylating graphene oxide, and modifying the resultant carboxylated graphene oxide using R-dithiocarbamic acid of formula (I). R1,R2=HO(CH2CH2O)n1H; R3=HO(CH2CH2O)n3H or COOH;and n1,n2,n3=5-20.
