Abstract: Microplastics (especially nano-sized microplastics) have become a global environmental problem due to their small size and difficulty in degradation, posing long-term threats to ecosystems and human health. Traditional methods for treating microplastics are inefficient and costly, and there is an urgent need for green and efficient solutions. In 2024, the group of Prof. Hongbing Deng from Wuhan University reported an innovative achievement that shrimp shells can adsorb microplastics. This project focuses on the core concept of “green chemistry” and adopts the approach of “popularizing cutting-edge research results”, transforming the aforementioned “shrimp shell microplastic adsorbent” innovation achievement into a popularization plan. This project is highly applicable and interesting, suitable for both home-based chemical exploration activities and the design of gradient scientific popularization display schemes for different audiences. Through the implementation of this project, the audience can understand scientific concepts such as adsorption, biomass materials, microplastics, fluorescence, colorimetry, and green chemistry, stimulating the interest of the general public, especially teenagers, in chemistry and cutting-edge innovative achievements.
