<p>PROBLEM TO BE SOLVED: To provide a metal recovery method which can recover metals efficiently by an inexpensive and simple method.SOLUTION: The metal recovery method uses a carboxylic acid ester of polysaccharide as a metal capture agent, which captures metals which dissolve in a solution. The present metal recovery method preferably selectively captures gold which dissolves in an acidic solution. As the carboxylic acid ester of polysaccharide, preferably used is an ester of a carboxylic acid and cellulose.</p> |
