Abstract (en)
[origin: EP1967577A1] A mixture of (a) hydrogen peroxide, (b) manganese complex salt(s) with organic nitrogen ligands and (c) readily biodegradable or at least bio-eliminatable complex former(s). A mixture containing (a) hydrogen peroxide, (b) manganese-based metal complex(es) of formula [L nMn mX p] z>Y q (I) in which Mn : Mn(III) or Mn(IV); X : a coordinating or bridging species; n, m : 1-3; p : 0-4; Y : a counter-ion, the type of which depends on the charge z on the complex; q : z/(charge on Y); L : a ligand of an organic molecule with a number of nitrogen atoms, coordinated via the N atoms to the Mn center(s) and (c) readily biodegradable or at least bio-eliminatable complex former(s).
