摘要： Methods for purifying a fluid may include injecting an impure fluid comprising carbon dioxide and at least one impurity into a first subterranean aquifer. The impure fluid may be circulated within the first subterranean aquifer for a period of time sufficient to separate at least a portion of the at least one impurity from the carbon dioxide to produce an at least partially purified fluid comprising the carbon dioxide, the at least partially purified fluid having a lower concentration of the at least one impurity than the impure fluid. The at least partially purified fluid may be removed from the first subterranean aquifer, wherein at least a portion of the at least one impurity remains entrained within the first subterranean aquifer.
