Pollutant Test
The
photograph above shows laboratory desicator jars with conservation
paper inside. The jar on the left contains MicroChamber© file/map
folder paper and the jar on the right contains traditional lignin
and sulphur free, alkaline buffered conservation paper. The orange
colour seen in the bottom of the two jars is and NO2 producing chemical
reaction. The picture was taken at the beginning of the experiment.
The
photograph below showing the jar on the right filled with buffered
paper and a fully developed cloud of yellow/orange pollutant smog
was taken after one hour. As you can see, the MicroChamber© paper
has removed the pollutant smog in the jar on the left. The orange
cloud of NO2 smog never developed in the MicroChamber© paper
jar, while the fully devoloped pollutant smog has blossomed and endured
in the jar containing the traditional buffered conservation paper.
Not only is the buffered paper unable to deal with the pollutant,
but the pH of the buffered paper had dropped to a very acidic pH of
2.4. In direct contrast, the MicroChamber© paper, despite having
removed the dense cloud of pollutant smog, retained its pH in the
neutral range.
