1. Ventilation method: air circulation can be used to take away the plastic smell of diluted schoolbags, or an electric fan can be used to blow it. It should be reminded that some people use negative oxygen ion generators to control low-concentration air pollution, but the control effect is not satisfactory, and negative oxygen ions are also easy to be converted into ozone, resulting in secondary pollution.

　　2. Adsorption method: Let the schoolbag contact and soak in a proper amount of cleaning agents such as milk, vinegar, baking soda, light salt water, waste tea, rice soup or rice washing water, grapefruit peel, pineapple pieces (good quality), white wine, dilute sulfuric acid (poor quality), etc., and after a certain period of time, part of the taste can be removed. Now there are many activated carbon air purification packages sold in supermarkets. Putting schoolbags in them can also remove the smell. The smaller the particles of activated carbon, the better the adsorption effect. However, it should be noted that the charcoal bag needs to be taken out and dried at regular intervals to discharge toxic substances.

　　3. Add fragrance: This method can cover the smell, but it cannot be eliminated. Aromatics are generally used in toys, daily commodities, cosmetic containers, household appliances and gardening equipment. Because toxic toys, toxic cosmetics, etc. are not uncommon now, they unconsciously endanger human health, so we should reduce daily contact and eat more fruits and vegetables to detoxify.

　　4. Plant absorption method: Plants have a strong ability to absorb harmful gases, such as cactus, chlorophytum, reed, ivy, Cycas, chrysanthemum, tortoise shell bamboo, silver queen, Jinhu, Herba Solani, Osmanthus fragrans, Anthurium andraeanum, Huang Jinmu, Yerong, Milan and so on. Generally speaking, plants with large leaves and herbs have a better effect of absorbing formaldehyde in school bags, such as chlorophytum, Eupatorium odoratum and so on. It should be noted that except for a few plants such as cactus and golden amber, most plants take oxygen at night and are not suitable for bedroom.
