Water pollution is a problem in many parts of the world and heavy metals in water can accumulate in our bodies and cause serious problems. Recently, scientists from Singapore and Switzerland have found a way to use a vegetable oil byproduct to filter heavy metals out of water.
Noticing that oilseed meals – waste byproducts of sunflower and peanut oil production – were attracted to heavy metal ions, the scientists did some tests and found that, with some adjustments, they could filter out 99.89% of heavy metals like platinum, lead and chromium from the water.
The great news is that the filters they created will filter out heavy metals as well as organic pollutants. The process is highly effective. It is also very cheap, since the filters come from a throwaway waste product.
