Application of nanocellulose in the field of environmental protection

1. Sewage treatment:

Nanocellulose can be used as an adsorbent and filter material for wastewater treatment. Its high specific surface area and rich functional groups make it have good adsorption capacity, which can effectively remove heavy metal ions, organic pollutants and pigments in water. Nanocellulose can also be used to construct nanocellulose-based composite membranes for isolating and filtering tiny particles and contaminants in wastewater.

2. Soil Repair:

Nanocellulose can be used for soil repair and adsorption and degradation of pollutants. The fibrous structure of nanocellulose can increase the porosity and aerability of the soil, helping to improve soil structure and moisture retention capacity. Meanwhile, nanocellulose can serve as a support or catalyst support for adsorbing or degrading organic pollutants in the soil.

3. Environmental monitoring:

Nanocellulose can be used to prepare environmental monitoring sensors and devices. By combining nanocellulose with functional materials, high sensitivity and selectivity sensors can be built to detect pollutants and harmful substances in air, water and soil, enabling real-time monitoring and early warning.

4. Improvement of water quality:

Nanocellulose can be used as a material for improving water quality, such as the preparation of ecological filters or plant root simulations. Nanocellulose has good biocompatibility and biodegradability, which can improve the ecosystem structure of water bodies and purify water quality.

5. Air purification:

Nanocellulose can be used for air filtration and purification to capture and remove particulate matter, organic gases and volatile organic compounds from the air. Nanocellulose-based filters have efficient filtration performance and sustainable regeneration, helping to improve air quality in indoor and industrial emissions.

The application of nanocellulose provides new technologies and strategies for environmental protection, which can effectively purify water and air, improve soil quality, degrade pollutants, and promote sustainable development and resource utilization.
