NOVELTY - Radioactive element scavenger comprises 0.5-4 wt.% of triterpenoid saponins, 0.5-4 wt.% maleic rosin octylphenol polyoxyethylene ether diester carboxylate, 0.1-2 wt.% coconut huaxin, 1-10 wt.% graphene oxide, 0.1-2 wt.% EDTA tetrasodium, 0.1-2 wt.% N,N-dicarboxymethyl glutamic acid tetrasodium, 0.1-1.5 wt.% polyethyleneimine, 0.01-0.5 wt.% sodium polyacrylate, 0-10 wt.% ethanol, 2-8 wt.% hydrogen peroxide, 0-3 wt.% triethanolamine, 0-3 wt.% sodium benzoate, 0-10 wt.% propylene glycol and water (balance). USE - The scavenger is useful for preparing radioactive element scavenging aerosol (claimed). ADVANTAGE - The scavenger: is environmentally friendly and non-toxic; exhibits good wettability; and has simple preparation method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the radioactive element scavenger, comprising (a) adding EDTA tetrasodium and N,N-dicarboxymethyl glutamic acid tetrasodium tetrasodium to water, stirring and dissolving to obtain a solution A, (b) adding triethanolamine and sodium benzoate to solution A, stirring and dissolving to obtain solution B, (c) adding triterpenoid saponin, maleic rosin phenol polyoxyethylene ether diester carboxylate and cocopolysaccharide to solution B, stirring and dissolving to obtain solution C, (d) adding polyethyleneimine, sodium polyacrylate and graphene oxide to solution C, stirring and dissolving to obtain solution D, and (e) adding ethanol, hydrogen peroxide and propylene glycol to the solution D, and stirring and dissolving to obtain the radioactive element scavenger; and (2) radioactive element scavenging aerosol, comprising a propellant and the radioactive element scavenger.
