An apparatus for use in the treatment of contaminated fluid is provided. The apparatus includes a body portion, made from a mixture of a waste adsorbent material and a binder material, for use in the removal of contaminants. The adsorbent material may be a nanosorbent material manufactured from self-assembled monolayers on mesoporous supports (SAMMS). The binder material, on the other hand, may include any thermoplastic material capable of binding the adsorbent material together to subsequently provide a composite material that can be shaped into a block. A method for treatment of contaminated fluid is also provided.
