The functional group of the anion resin includes various amines, and the strongly basic functional group is a quaternary amine; the weakly basic functional group has a primary amine, a secondary amine, a tertiary amine, and the like. The quaternary amine is generally a chloride salt and a hydroxide type, i.e., R-N(CH3)3C1, R-N(CH3)3OH, wherein R represents a carbon chain skeleton.
The strong base anion exchange resin contains a strong basic group, such as a quaternary amine group (also known as a quaternary amine group)-NR3OH (R is a hydrocarbon group), which is capable of dissociating OH in water and is strongly alkaline. The positively charged group of this resin can be adsorbed and combined with an anion in the solution to cause anion exchange. This resin is very dissociable and works well at different pHs. It is regenerated with a strong base such as NaOH.
Lanlang has several types of strong base anion exchange resin.
One of it is the TA207 SBA resin.
At present, the groundwater chloride ion in many areas exceeds the standard, and TA207 resin can be used for removal. Generally, it needs to be regenerated by using NaOH solution.
