Abstract
The manganese substituted heteropolytungstates alpha-[(Mn(H2O))SiW11O39](6- ) (1), alpha-[(Mn(H2O))(2)SiW10O38](8-) (2), alpha-[(Mn(H2O))(3)SiW9O37](10 -) (10-) (3), beta-[(Mn(H2O))(3)SiW9O37](10-) (4), and alpha-[(Mn(H2O))(3)P W9O37](9-) (5) were applied as catalysts for low-temperature bleaching of s tained cotton cloth. The bleaching activity of this series of catalysts is correlated to the fibre-damage induced to cotton cloths during washing as w ell as to the stability of the catalysts under simulated washing conditions .
