| 内容記述 | 染料視覚阻害剤を開発する目的で, 13種の澱粉, 3酸性染料, 3塩基性染料, 及び3両性染料を用いて, 澱粉粒への染料吸着を調べた。染料吸着量は, 塩基性染料>酸性染料>両性染料であった。酸性染料中, 小径澱粉粒が大径澱粉粒より高い吸着を示した。陽イオンの染料吸着に与える影響は, 二価が一価より高かった。イオンの高濃度(イオン強度0.1)では, 酸性染料及び塩基性染料の吸着は低下したが, 両性染料は, 特定の澱粉については増加を示した。全澱粉について, メタノール中での吸着は, ほぼ零に近かった。メタノール, エタノール, プロパノール, 及びブタノール中での溶媒蒸発法による吸着では, メタノールとエタノールが高く, プロパノール, 次にブタノールの順に低下した。メタノール蒸発法による染料吸着は, 水溶液中の吸着より高かった。塩基性染料及び両性染料は, 澱粉粒径が大となるに従い吸着量が高かった。これらの現象を説明するために, 澱粉粒の表面及び内部に於けるイオン結合形成の可能性が提案された。 | |||||||||
