Yes. You should by William Crawford's "The keepers of light". Page 140, you
can read : "Weigh out one gram of paper, tear it up and place it in a
beaker. Then mash it with a stirring rod in 20 ml of distilled or de-ionized
water. Add 50 ml more water and cover the beaker. After one hour, stir the
content and mesure the pH with the meter."
You can get plenty of information in this book.
