We are trying to trace the fate of paper pulp in seawater, and need a 
method of identifying the fibers.

I am looking for information on how to indelibly dye or stain paper
and cardboard. The paper and cardboard will be shredded in a paper 
pulper.  We need to be able to indelibly stain all of the paper 
particles that are produced by the pulper.  This stain
must be indelible to seawater.  After exposing the paper particles 
to seawater, we would like to remove the stain via a solvent and 
measure the quantity of stain extracted spectroscopically (such as 
fluorescence).

I would also be interested in any other technique which might enable us 
to identify/quantify  the fiber concentration in seawater.

Thanks,
