AI Technical Summary
Technical Problem
Existing technologies are ineffective at removing nanoscale microplastic particles, especially in water bodies, and traditional methods may lead to secondary pollution or waste of resources.
Method used
By treating crustacean shells with acids and alkalis to preserve their structure and functional groups, porous adsorbent materials are prepared. These materials capture nanoplastic particles using their rough surfaces and porous structures, and can be hot-pressed into sheets for wastewater treatment.
Benefits of technology
It achieves efficient capture and removal of nanoplastic particles, avoids resource waste, provides a closed-loop path for waste recycling, and the resulting boards have excellent thermal stability.
