Abstract
Description
(i)水性液を脱気する工程、
(ii)電界を水性液に印加する工程、
を含む、水性液を通して電流を伝導又は通過させる方法を提供する。
(i)水性液を脱気する工程、及び
(ii)脱気された液体を電気透析に付する工程、
を含む、水性液からイオンを濃縮、分離又は除去するための方法を提供する。
ここで報告される実験的研究においては、水道水から蒸留水を、粗ろ過、活性炭ろ過、逆浸透ろ過、そして最後に蒸留するという一連のプロセスにより製造して、層流の清浄空気キャビネット内に収容したパイレックス(登録商標)ガラス貯蔵容器内に入れた。
単一蒸留水について得られた結果:
所定の範囲の条件下で水の導電率について得られた結果を表1にまとめて示す。これらの結果は、その測定が行なわれたしかるべき条件とともに、標準的な文献値と比較されている。全ての値はμScm-1単位である。温度及びpHの値はかっこ内に示されている。
電子透析に対する塩水脱気の効果:
静電界の影響下で水中のイオンに対し作用する力は、水中の各々の特定イオンについての電気移動度の値により十分に説明することができる。例えば、イオンの移動度U+-は、印加された場Eの強さに対するドリフト速度S+-(印加された場の方向における)の比として表すことができる。
