Activated carbon can adsorb impurities in water. For example, survival experts often use carbon to obtain drinkable water, but it also has a lifespan. How to check if the activated carbon in pure water equipment is saturated?

1. Take a certain amount of new activated carbon and use colored water as the adsorption test. For example, use a beverage bottle, add an appropriate amount of activated carbon, and add cold water to the bottle. Then pour the activated carbon into the bottle, drop a small amount of yellow medicine or methyl blue, shake or let it stand for a certain time, and then remove the aqueous solution from the bottle, which is aqueous solution A.

2. In addition, the process is repeated again, only using drugs without adding activated carbon, as an aqueous solution B that has not been solved by activated carbon.

3. In the end, the applied activated carbon can be used as a pure water equipment for testing. By observing where the water color in the bottle is close to aqueous solution A or B, it can be determined whether the activated carbon also has practical application effects. Pay attention to fixing the amount of activated carbon added, water flow rate, drug dosage, and shaking time.

4. The porosity of activated carbon can be roughly divided into large and medium composite microporous plates, which refer to the presence of these three types of porosity in each activated carbon. The composition of which one accounts for the most depends on the raw material materials and production standards.

5. It is proposed to use coconut shell activated carbon. Due to its high adsorption capacity, the apparent density of coconut shell activated carbon is mostly less than 0.45g/ml, and the fineness is mostly less than 5%. When the proportion of pure water equipment activated carbon and residual carbon is lower, it can be expressed that there are not too many carbonates and residues in it, and the proportion of porosity is higher, so the relative adsorption capacity is improved.
