AbstractThe preparation and use of aqueous 0.2% chlorine dioxide as it was practiced at the private conservation studio of paper conservator Christa M. Gaehde in the 1990s is described for the record. The bleach was used predominantly on prints printed in black printing inks on machinemade lignin-free paper. The treatment sequence involved washing in deionized water; immersion in the chlorine dioxide solution or a local brush application of the bleach in the print margins; rinsing in deionized water; neutralization of residual bleach by misting 1% sodium thiosulfate solution recto and verso; four rinsing baths in deionized water, the fourth one conditioned with calcium hydroxide to pH 9. Preparation of the bleach required special precautions in handling the sodium chlorite and formaldehyde.

High Treatment

In order to verify the treatment performance of newly developed johkasous with membrane separation, for household use, three johkasous of different types were used for experimental study. It was found that each of these johkasous has a high treatment performance for removing BOD, nitrogen, and can be operated steadily by monitoring the function and maintaining the devices at every three months and by withdrawing accumulated sludge at every six months. It was also found that periodical cleaning of the membrane by sodium hypochlorite solution and neutralizing cleaning wastewater by sodium thiosulfate solution at every six months is important to maintain a steady permeability of the membranes. No adverse effects on treatment performance was observed by leached sodium hypochlorite solution from the membrane at membrane cleaning.

Direct Spectrophotometry

Abstract Samples of wheat, flour, dried milk, or pecans are ashed in a modified Schoniger oxygen flask and bromide is determined by titration with standardized sodium thiosulfate solution or by direct spectrophotometry. A collaborative study indicated about 90% recovery at the 100 ppm bromine level. Standard deviations from 3.7 to 35.3 ppm and from 2.8 to 21.8 ppm were obtained for the titration and spectrophotometric determination, respectively.
