Abstract
The present invention relates to a method of using foam to remove pollutants and/or heavy metals from a flowable media. The method may include providing a foam that may include cavities wherein the cavities may include an adsorbent composition of iron oxyhydroxy granules. The iron oxyhydroxy granules may have a BET surface area of >100 m/g and a mean particle size of 0.1 mm-2 mm. The method may further include passing a flowable media containing pollutants and/or heavy metals through the foam wherein the pollutants and heavy metals may be removed from the flowable media by the iron oxyhydroxy granules. A method of manufacturing the foam is also disclosed. The method may include introducing an adsorbent composition into a liquid reaction composite to form a mixture and adding an isocyanate reaction component to the mixture to form the foam.
