Abstract:
A polyelectrolyte coated fly ash is described with a method of making and a method of using for the adsorption of a contaminant from a solution. The polyelectrolyte coated fly ash may be made by treating the oil fly ash with acid, and then contacting the product with a positive polyelectrolyte to create a first polyelectrolyte layer, and then with a negative polyelectrolyte to create a negative polyelectrolyte layer. The resulting polyelectrolyte coated fly ash quickly adsorbs contaminants from solution, and may be cleaned and reused.
