How to use activated carbon
Activated carbon is a porous adsorption material that is widely used in household, medical, industrial and other fields. In recent years, with the increase in environmental awareness, the use of activated carbon has become a hot topic. This article will combine the hot content on the Internet in the past 10 days to give you a detailed introduction to the purpose, usage and precautions of activated carbon.
1. Main uses of activated carbon
The adsorption capacity of activated carbon makes it useful in many fields. The following are the most discussed uses of activated carbon on the Internet in the past 10 days:
| use | Application scenarios | heat index |
|---|---|---|
| air purification | Formaldehyde removal for new homes and odor removal for cars | ★★★★★ |
| water treatment | Water purifier filter element, fish tank filtration | ★★★★☆ |
| personal care | Teeth whitening, skin care ingredients | ★★★☆☆ |
| food industry | Syrup decolorization and wine purification | ★★☆☆☆ |
2. The correct way to use activated carbon
According to recent hot discussions among netizens, the following are some of the most popular ways to use activated carbon:
1. Household formaldehyde removal
Place activated carbon bags in closed spaces such as wardrobes, drawers, new furniture, etc., at a concentration of 50-100g per square meter. It is recommended to replace it once a month. Used activated carbon can be reused 2-3 times after exposure to the sun.
2. Water purification treatment
Put granular activated carbon into the water purifier filter element, and control the water flow rate at 0.5-1L/min for the best effect. It needs to be rinsed for 10 minutes for the first time and replaced every 3-6 months.
3. Deodorize the refrigerator
Put 100g of activated carbon into a breathable cloth bag and place it in the corner of the refrigerator. Taking it out and drying it for 6 hours every 2 months can restore the adsorption capacity, and the service life is about 1 year.
3. Precautions when using activated carbon
| Things to note | reason | solution |
|---|---|---|
| Avoid direct contact with skin | May cause dryness or allergies | Use sealed packaging |
| Keep away from children and pets | May be dangerous if swallowed | placed high |
| Regular replacement | Failure after adsorption saturation | Create a replacement reminder |
| Pay attention to the storage environment | Moisture reduces effectiveness | Sealed and moisture-proof storage |
4. Frequently Asked Questions about Activated Carbon Use
Q: Can activated carbon completely remove formaldehyde?
A: No. The adsorption rate of activated carbon for formaldehyde is about 60-80%, so it is recommended to use it with ventilation.
Q: Can activated carbon still be used if it becomes heavy?
A: A change in weight indicates that the adsorption is saturated and needs to be replaced or regenerated.
Q: How to judge the quality of activated carbon?
A: High-quality activated carbon has developed pores and will produce dense bubbles when placed in water and will sink slowly.
5. Activated carbon purchase guide
According to recent e-commerce platform sales data, the activated carbon purchasing indicators that consumers are most concerned about are as follows:
| index | Premium standards | Detection method |
|---|---|---|
| Iodine adsorption value | ≥1000mg/g | View test report |
| particle size | 2-4mm | naked eye observation |
| Packaging tightness | vacuum packaging | Check packaging status |
| Source of raw materials | Coconut shell/bamboo charcoal | View product description |
Through the above detailed introduction, I believe you have mastered the correct use of activated carbon. Reasonable use of activated carbon can make our living environment healthier and more comfortable. Remember to replace activated carbon regularly to maintain its purification effect.
