Abstract
The invention relates to a device (22) for changing the pH of a solvent in which a substance is dissolved. The device includes a housing (24) in contact with the solvent through a housing wall (26) that is permissive to the solvent and the substance. The housing contains enzymes adapted for converting the substance in order to provide hydrogen or hydroxyle ions; the housing wall being non-permissive to the enzymes.
Claims17
