Ion Ion exchange resin is a polymer compound with functional groups (active groups with exchangeable ions ), having a network structure and insoluble. Usually spherical particles.
Ion exchange Resin The full name consists of classification name, backbone (or gene) name, and basic name. There are two types of pore structures: macroporous and gel type. Those with physical pore structures are called macroporous resins, with "macroporous" added before the full name. Acidic classifications add "cation" before the name, and basic classifications add "anion" before the name. For example: macroporous strong acid polystyrene and cation exchange resin. Ion exchange resins can also be divided according to the type of matrix into styrene-based resins and
acrylic based resins. The type of chemically active groups in the resin determines the main properties and categories of the resin. First, they are divided into cation resins and anion resins, which can respectively exchange ions with cations and anions in the solution. Cation resins are further divided into strong acid and weak acid types, while anion resins are divided into strong base and weak base types (or further into medium strong acid and medium strong base types). 中的阳离子和阴离子进行离子交换。阳离子树脂又分为强酸性和弱酸性两类，阴离子树脂又分为强碱性和弱碱性两类（或再分出中强酸和中强碱性类）。
