Material compositions have multifunctionality in abatement of water pollution: They are capable of removing hydrocarbons along with various types of other pollutants, such as metals and metal oxides, and phosphates and other organic material, from water streams. In certain embodiments, the multifunctional compositions are comprised of biochar particles, activated carbon particles, or metal (or metal oxide) nanoparticles bound to a cellulosic or other organic matrix material, which are adhered to styrene-butadiene-styrene granules embedded in an M-Class rubber matrix. Methods of synthesis of the multifunctional compositions and products, including filter cartridges and filters, that use such compositions are also disclosed. |
