SamenvattingA comparative study of the ability of six different reducing agents (sodium borohydride, tetramethylammonium borohydride, tetraethylammonium borohydride, sodium sulfite, sodium thiosulfate or sodium hydrosulfite) to elimintate chloramine-t bleaching residues from paper has been completed. The investigation has been carried out as a function of anti-chlor concentration (0. 1 to 2%) and solvent (water or alcohol). Evaluation of results took place after five months of natural aging in the dark and showed the borohydrides to have similar abilities to successfully remove oxidizing residues. Treatment of bleached paper with the sulfur-based reducing agents showed evidence of incomplete removal of bleaching residues.
