How do you make activated charcoal with water?

Published in Activated Charcoal 2 mins read

The process of making activated charcoal using water involves a specific series of steps, where water is used for rinsing, but not for activation directly. The activation process utilizes a chemical and heat, based on the provided reference. Here is a step-by-step breakdown:

Steps to Make Activated Charcoal (with Water Involved in Rinsing)

Step Description
1 Powder the charcoal: Begin by finely powdering your regular charcoal. This increases the surface area for activation.
2 Prepare Calcium Chloride Solution: Make a 25% solution of calcium chloride by weight. This acts as the activating agent.
3 Create a Paste: Mix the powdered charcoal with the calcium chloride solution to form a paste.
4 Dry the Paste: Spread the paste out and allow it to dry completely.
5 Rinse: Rinse the dried charcoal paste with clean water to remove excess calcium chloride.
6 Bake: Bake the rinsed charcoal at 225 degrees Fahrenheit for 30 minutes to complete the activation process.

Explanation

  • The reference specifies using calcium chloride, not water, as the primary activating agent.
  • Water is used to remove excess calcium chloride in step 5.

Key Points:

  • The activation process happens by using a chemical to create more pores on the charcoal surface.
  • This process increases the ability of charcoal to absorb substances.
  • The baking at 225 degrees Fahrenheit is essential for driving off any remaining chemicals.
