杜笙® 螯合離子交換樹脂 Tulsion® CH-90
去除+2價金屬離子的選擇性螯合離子交換樹脂
SELECTIVE ION EXCHANGE RESIN FOR REMOVAL OF BIVALENT METALS .
TULSION® CH-90是一款具有iminodiacetic官能基及非常耐久型的巨孔狀的選擇性螯合型離子交換樹脂。
TULSION® CH-90適用于制程或廢水中從一價金屬離子中選擇性的去除二價金屬離子的應用。二價金屬離子可以很容易的與單價金屬離子分離,如Ca+2等離子。
此二價金屬離子的去除應用, 如電鍍及金屬酸洗, 水解冶金; 電池制造業的鉛去除, 電子業等應用。
