Resumo: A newly effective system was used to bleach ligno-cellulosic textile materials. This system is based on two different newly synthesized natrium oxo-diperoxo molybdates, Na2[MoO (O2)2(C2O4)] and Na2[MoO (O2)2(C6H6O7)]. These two compounds were characterized by means of cyclic voltammetry, and the bleached fabrics were fully characterized by measuring their whiteness index, percent loss in fabric weight and the content of lignin in the fabric. The obtained results revealed that good whiteness index of the bleached linen-cotton fabrics (50% linen and 50% cotton) and low content of lignin could be obtained by soaking the fabric for 55 min at 90 °C in a solution containing 3.5% of molybdate complex and 3.5% H2O2.
