The related research results were published in the latest issue of the online open journal Chemical frontier. The team of Elza Bonntempi of the University of Brescia in Italy introduced synthetic raw materials for this 'green' adsorbent including sodium alginate and silica fume, the former. It can be extracted in large amounts from seaweed, which is a by-product produced in large quantities during the production of silicon alloys. The synthesis process is simple and can be produced on a large scale.
The researchers used pollutants 'methylene blue dye' for wastewater testing. The results showed that this new material can adsorb and remove high concentrations of dyes with an efficiency of 94%; it can also adsorb particulate matter in diesel exhaust.
Researchers say that this new material consumes less energy and is more environmentally friendly than activated carbon. Currently, activated carbon is widely used to reduce atmospheric and waste water pollution, but it is expensive. New materials are widely used for coatings. , Can be sprayed, can also be used for 3D printing materials, is expected to be designed as a water purifier or cover the building facade to remove airborne particles.
