Method and apparatus for the evaporation of a solution into the ambient air. The apparatus contains a reservoir having at least one elastic wall; a first compartment outside the reservoir having an opening to the ambient air; a passage which may be intermittently opened and closed, connecting the reservoir to the first compartment; and, an absorbent material placed on a support which is outside both the reservoir and the first compartment, and which is in contact with the first compartment. By exerting pressure on the elastic wall of the reservoir, solution may be transferred from the reservoir to the first compartment through the passage when it is open. The passage is kept closed during the time intervals between intermittent transfers of the solution. The portion of solution which has been transferred to the first compartment is gradually and continuously transferred to the absorbent material for evaporation to the ambient air.

A method for the evaporation of a solution which comprises: (a) introducing a certain volume of said solution (18) into a reservoir (16) having at least one elastic wall (13); (b) intermittently opening a passage (17,18) connecting said reservoir and a first compartment (26) outside said reservoir,

A method for the evaporation of a solution which comprises: (a) introducing a certain volume of said solution (18) into a reservoir (16) having at least one elastic wall (13); (b) intermittently opening a passage (17,18) connecting said reservoir and a first compartment (26) outside said reservoir, for the transfer of a portion of said solution from said reservoir to said first compartment; (c) intermittently opening an opening (29) in said first compartment to the ambient air; (d) exerting an external pressure on said elastic wall of said reservoir, when said opening (29) and said passage (17,18) are open, sufficient to transfer said portion of said solution from said reservoir to said first compartment, and gradually and continuously transferring a portion of the solution (34) contained in said first compartment to an impregnation member (31) consisting of a material capable of absorbing a liquid, said member being placed on a support (21) outside said reservoir and outside said first compartment; (e) closing said opening of said first compartment and closing said passage; and (f) keeping said opening and said passage closed during the time intervals between intermittent transfers of portions of said solution from said reservoir to said first compartment.
