1. 强碱型阴离子交换树脂：主要是含有较强的反应基如具有四面体铵盐官能基之-N+(CH3)3，在氢氧形式下，-N+(CH3)3OH-中的氢氧离子可以迅速释出，以进行交换，强碱型阴离子交换树脂可以和所有的阴离子进行交换去除。
1. Strong base anion exchange resins: mainly containing strong reaction groups such as - N+ (CH3) 3 with tetrahedral ammonium salt functional groups. In the form of hydrogen and oxygen, the hydrogen and oxygen ions in - N+ (CH3) 3OH - can be rapidly released for exchange. Strong base anion exchange resins can exchange and remove all anions.
这类树脂含有强碱性基团，如季胺基(亦称四级胺基)-NR3OH(R为碳氢基团)，能在水中离解出OH-而呈强碱性。这种树脂的正电基团能与溶液中的阴离子吸附结合，从而产生阴离子交换作用。
These resins contain strong alkaline groups, such as quaternary amines (also known as fourth-order amines) - NR3OH (R is hydrocarbon group), which can dissociate OH - in water and show strong alkalinity. The positive group of the resin can be combined with the anion adsorption in the solution, resulting in anion exchange.
这种树脂的离解性很强，在不同pH下都能正常工作。它用强碱(如NaOH)进行再生。
The resin has strong dissociation and can work normally at different pH. It is regenerated with strong alkali (such as NaOH).
2. 弱碱型阴离子交换树脂： 这类树脂含有弱碱性基团，如伯胺基(亦称一级胺基)-NH2、仲胺基(二级胺基)-NHR、或叔胺基(三级胺基)-NR2，它们在水中能离解出OH-而呈弱碱性。这种树脂在多数情况下是将溶液中的整个其他酸分子吸附。它只能在中性或酸性条件(如pH1～9)下工作。它可用Na2CO3、NH4OH进行再生。
2. Weak base anion exchange resins: These resins contain weak basic groups, such as primary amino group (also known as primary amino group) - NH2, secondary amino group (secondary amino group) - NHR, or tertiary amino group (tertiary amino group) - NR2, which can dissociate OH - in water and show weak alkalinity. In most cases, this resin adsorbs the whole other acid molecules in the solution. It can only work under neutral or acidic conditions such as pH 1-9. It can be regenerated with Na2CO3 and NH4OH.
3 . 对阴离子的吸附
3. Adsorption of anions
强碱性阴离子树脂对无机酸根的吸附的一般顺序为：
The general order of adsorption of inorganic acid radicals by strong basic anion resins is as follows:
SO42-> NO3- > Cl- > HCO3- > OH-
SO42-> NO3-> Cl-> HCO 3-> OH-
弱碱性阴离子树脂对阴离子的吸附的一般顺序如下：
The general order of adsorption of anions by weakly basic anion resins is as follows:
OH-> 柠檬酸根3- > SO42- > 酒石酸根2- >草酸根2- > PO43- >NO2- > Cl- >醋酸根- > HCO3
OH - > Citrate 3 - > SO42 - > Tartrate 2 - > Oxalate 2 - > PO43 - > NO2 - > Cl - > Acetate - > HCO 3
