摘要:
A contaminant precipitating composition and method are disclosed. The composition comprises a water soluble, branched, polydithiocarbamic acid salt effective for the purpose of precipitating contaminants from an aqueous solution. The method comprises adding an amount of the composition effective for the purpose to the aqueous solution so as to complex, precipitate and remove contaminants from the aqueous solution.
