Abstract
A polyelectrolyte-surfactant complex, a method of removing a toxic substance from contaminated soil or contaminated groundwater using a polyelectrolyte-surfactant complex and a method of making a polyelectrolyte-surfactant complex. The polyelectrolyte-surfactant complex is made from a complexated recombinant intrinsically disordered protein that has been electrostatically conjugated to an anionic surfactant to provide enhanced liquid-liquid phase separation properties.
Claims15
A method of removing a substance from soil or groundwater, the method comprising:
- receiving a polyelectrolyte-surfactant complex comprising a cationized protein that has undergone electrostatic conjugation with an anionic surfactant such that the polyelectrolyte-surfactant complex has a first liquid and a second liquid such that a complexated protein is present in the first liquid in a greater concentration than in the second liquid;
- combining the polyelectrolyte-surfactant complex with at least one of the soil and the groundwater such that the substance contained therein absorbs into the complexated protein within the first liquid while the second liquid remains predominantly in contact with the groundwater or soil;
- and
- separating the first liquid and the substance extracted thereto from the second liquid.
