Abstract

Fremgangsmåte for bleking av masse, og som omfatter trinnet for bleking av massen med hydrogenperoksyd og en effektiv mengde av minst ett biologisk nedbrytbart 1-aminoalkan-l,1-difosfonat-chelateringsmiddel for å forbedre ble-kingen av massen. Det beskrives også anvendelse av et 1-aminoalkan-l, 1-difosfonat for å forbedre bleking av masse med hydrogenperoksyd, samt forbehandling av masse med et 1-aminoalkan-l , 1-difosfonat før trinnet for bleking med hydrogenperoksyd. Til slutt beskrives også avsverting av masse i nærvær av 1-aminoalkan-1,1-difosfonat.
