Lewatit ^(®){ }^{\circledR} MonoPlus TP 207 is a weakly acidic, macroporous cation exchange resin with chelating iminodiaceticacid groups designed for the selective extraction of heavy metal cations from weakly acidic to weakly basic solutions. Divalent cations are removed from neutralized waters in the following order (decreasing affinity): Lewatit ^(®){ }^{\circledR} MonoPlus TP 207 是一種弱酸性、大孔陽離子交換樹脂,具有螯合亞氨基二乙酸基團,設計用於從弱酸性溶液中選擇性萃取重金屬陽離子至弱鹼性溶液。按以下順序從中和水中去除二價陽離子(親和力降低):
The monodisperse, uniform sized beads of Lewatit ^(o+){ }^{\oplus} MonoPlus TP 207 are mechanically and osmotically more stable than ion exchange resin beads with heterodisperse bead size distribution. Additionally they offer superior kinetic behavior which leads to faster uptake of cations and a better utilization of capacity. Therefore it is suitable for use in the following applications: Lewatit ^(o+){ }^{\oplus} MonoPlus TP 207 的單分散、大小均勻的微珠在機械和滲透方面比具有異分散微珠大小分佈的離子交換樹脂微珠更穩定。此外,它們還具有出色的動力學特性,從而更快地吸收陽離子並更好地利用容量。因此,它適用於以下應用:
the selective removal of metal contaminants from processing baths 選擇性地去除加工槽中的金屬污染物
the concentration, extraction and recovery or heavy metals from hydrometallurgical solutions 濕法冶金溶液中的濃縮、提取和回收或重金屬
the recovery of useful metals from electroplating rinse waters 從電鍍沖洗水中回收有用金屬
the selective trace removal of heavy metals from industrial metal surface finishing effluents, even in presence of high calcium concentrations 選擇性地去除工業金屬表面處理流出物中的重金屬痕量,即使在高鈣濃度存在的情況下也是如此
the selective removal of heavy metals out of contaminated ground and waste water streams for potable water production and ground water remediation 從受污染的地面和廢水流中選擇性去除重金屬,用於飲用水生產和地下水修復
The selective extraction of heavy metal cations by Lewatit ^(8){ }^{8} MonoPlus TP 207 is also achieved in presence of complexing agents such as nitrogen compounds (e.g. ammonia, aliphatic and aromatic amines), multivalent carboxylic acids (e.g. citric, gluconic, tartaric, oxalic acid) and phosphates (e.g. sodium polyphosphate, tetrasodium diphosphate). Lewatit ^(8){ }^{8} MonoPlus TP 207 還可以在絡合劑(如氮化合物(如氨、脂肪族和芳香胺)、多價羧酸(如檸檬酸、葡萄糖酸、酒石酸、草酸)和磷酸鹽(如聚磷酸鈉、二磷酸四鈉)等絡合劑存在下選擇性萃取重金屬陽離子。
