Water purification technology gives "coffee foaming body" a new meaning.
Scientists have proved through experiments that waste coffee grounds can not only be used as road building materials and biodiesel, but also effectively remove heavy metal ions such as lead and mercury from water. A team of scientists led by the Genoa's Istituto Italiano di Tecnologia Institute of Technology in Italy have developed a foam "filter" made from coffee grounds. The foaming "filter" is made of 60% coffee powder and 40% silicone elastomer.
When dried, these mixtures form a solidified form and leave small pores, thus forming a foaming body with filtering effect.
In the experimental results, the researchers found that the foam filter successfully removed 99% of mercury and lead from static water within 30 hours. Even in flowing water, 67% of the lead that is harmful to health has been successfully removed.
The findings are published in the journal ACS Sustainable Chemistry and Engineering (ACS Sustainable Chemistry & Engineering).
