Activated carbon

At 03:48 AM 7/18/99 -0400, George Slusarczuk <yurko at warwick_net> opined:
Obviously, AC made from animal bones will contain a lot of phosphorus,
that from wood will have substantially less and AC made from
once-distilled petroleum tar -- only traces of phosphorus, if that.

George, this is not at all obvious to me.   Can you explain how you reached
this conclusion?
