Well, my test electrode has been bubbling nicely in solution for over 24 hours
now, and shows no sign whatever of having the binder dissolve or anything. Also,
I haven't noticed any dropoff in current from "anode loading" i.e. from the
anode becoming more resistive over time. So, early tests are looking good.
Another thing I like about these (3/8x12") carbon electrodes is that the
alligator clips on my little battery charger fit the carbon electrodes very
well. Most car battery terminals are close to being cylindrical slugs of lead,
and so the charger leads are designed to clamp nicely to a round shape. They
work very well.
If this works OK for another day I'm going to declare success and buy a few more
of these and try drilling and tapping No. 10 holes on one end for brass screws.
I have lots of crimp-on fittings, and if I wanted to have several anodes in
parallel around the periphery of a container (as I often do to achieve a more
uniform field i.e. "line of sight") this would make it a simple way to effect
positive connectivity between wire and carbon.
I'm happy about this so far.
