Description
プルシアンブルー(大日精化工業製品クロモファイン)を用いて1重量%濃度のプルシアンブルー水溶液を調製し、このプルシアンブルー水溶液中にカーボンクロス(東レ製品トレカ;空孔率50%、厚さ200μm、抵抗値0.5Ω)を室温下(25℃)で約30分間浸漬した。その後、プルシアンブルー水溶液からカーボンペーパーを引き上げ、60℃で約1時間乾燥してプルシアンブルーを固定したカーボンペーパーを得た。
Claims (2)
- カーボンペーパーまたはカーボンクロスを0.1〜5%濃度のプルシアンブルー水溶液に温度5〜35℃で含浸させた後、温度20〜70℃で乾燥処理を行うことにより、プルシアンブルーをカーボンペーパーまたはカーボンクロスに固定せしめた陽イオン物質分離用材料を、プラス側の電極に取り付け、電圧5〜100V、電流0.01〜1Aで通電することを特徴とする、陽イオン物質分離用材料に吸着している陽イオン物質の分離方法。
- カーボンペーパーまたはカーボンクロスが、空孔率40〜80%、厚さ100〜300μm、抵抗値0.2〜1Ωである請求項1記載の陽イオン物質の分離方法。
