详情介绍
Lewatit VP OC 1026是一种含有磷酸二-2-乙基己酯(D2EHPA)的苯乙烯 - 二乙烯基苯甲醚共聚物的大孔树脂。该萃取剂已经在聚合过程中直接包含在内,这导致活性成分的高浓度。此外,操作过程中萃取剂的损失被好小化(只要工艺溶液的pH值和冲洗水的pH值保持在pH值4以下)。以下列顺序按照以下顺序吸附阳离子:Ti4。 &GT; Fe 3+> IN3。 &GT; Sn2,4 +> Sb3'&gt; Bi 3'&gt; V02&QUOT; &GT; BE2&QUOT; &GT; AL3&QUOT; &GT;锌&QUOT; &GT; PB2&QUOT; &GT; CD2&QUOT; &GT;钙&QUOT; &GT; M n2“ &GT; CIF&QUOT; &GT;非斯&QUOT; &GT; CO2&QUOT; &GT; NI2&QUOT; &GT; MG2&QUOT; &GT; Cr +&gt; &GT; Alkali应用领域:lt可以g通常假设这些组分从水溶液中接收,其可以通过液体萃取剂D2EHPA从硫酸和盐酸溶液中作为pH的函数除去,例如:二价锌离子,铀(UO2- ),钒(VO-),三价镧系元素,铟,铁,al系元素四价离子,钛。Lewatit®VP OC 1026的优点与溶剂萃取相比:不需要有机溶剂,无相分离问题 - 与常规珠粒型离子交换树脂类似的简单设备重要提示应用:与已知离子交换树脂的物理和化学性质有明显区别。应仔细观察以下页面中汇总的产品数据。必须强调:Lewatit VP OC 1026的活性成分是酸酯的形式。这意味着所提供的表格可以直接使用。应避免暴露于氢氧化钠或碳酸钠,因为活性成分将从树脂中排出。处理溶液和漂洗水的pH值也应始终< pH 4.树脂漂浮在液体表面。因此,色谱柱应该在色谱柱的头部配备适当的分配板并在上游操作。由于具体的制造方法,树脂具有相对高百分比的离子珠粒。因此建议使用惰性树脂(Lewatite IN 42)来保护头部分配器不被堵塞。为了保护底部分配器,可以使用砾石层回流只能通过酸性,好低4%的含盐溶液以下流模式进行。反洗水通过位于离子交换床下方的特殊输出管排出。只有在进行彻底预过滤的情况下,才能使用树脂而不反洗。在这种情况下,色谱柱设计为填充床,干舷只有10%。

Lewatit® VP OC 1026 is a macroporous resin based an a styrene-divinylbenzol copolymer containing di-2-ethylhexyl phosphate (D2EHPA). This extracting agent is already included directly during the polymerization, which leads to a high concentration of the active ingredient. In addition, a loss of extractant during operation is minimized (as long as the pH of the process solution as well as rinse water ist kept below pH 4).

Cations are adsorbed by Lewatit® VP OC 1026 in the following order:

Ti4. > Fe3+ > In3. > Sn2,4+ > Sb3' > Bi 3' > V02" > Be2" > Al3" > Zn2" > Pb2" > Cd2" > Ca2" > M n2" > CIF" > Fez" > CO2" > Ni2" > Mg2" > Cr+ > > Alkali

Fields of application:

lt can generally be assumed that Lewatit® VP OC 1026 those components receives from aqueous solutions, which can be removed by means of the liquid extractant D2EHPA from sulfur and hydrochloric acid solutions as a function of pH, e.g.:

  • divalent ions of zinc, uranium (UO2-), vanadium (VO-)
  • trivalent ions of lathanides, indium, iron, aluminium
  • tetravalent ions of actinides, titanium

Advantages of Lewatit® VP OC 1026 compared to solvent extraction:

  • no organic solvent required
  • no phase separation problems
  • simple equipment similar to conventional bead type ion exchange resins

Important hints for application:

There is a marked distinction in its physical and chemical properties from those of the known ion exchange resins. The product data summarized in the following pages should be carefully observed. lt has to be emphazised that: The active ingredient of Lewatit® VP OC 1026 is in the form of the acid ester. This means that the form supplied can be directly used. Exposure to sodium hydroxide or sodium carbonate should be avoided since the active ingredient will be displaced from the resin. Also the pH of process solution and rinse water should always be < pH 4. The resin is floating to the liquid surface. Therefore the column should be equipped with an adequate distribution plate at the column's head and be operated upstream.

Due to the specific method of manufacturing the resin has a relatively high percentage offine beads. Therefore it is recommended to use inert resin (Lewatite IN 42) to protect the head distributor against plugging. To protect the bottom distributor a gravel Iayer can be applied.

Backwash can only be carried out in downflow mode by means of an acidic, in minimum 4 % salt containing solution. Backwash water is discharged through a special outl pipe positionned below the ion exchange bed.

The resin can be used without backwashing only in the case that a thorough - pre filtration is carried out. In this case the column is designed with a packed bed, having only 10 % freeboard.
