High Quality Chelating Resin

Chelating resins also known as specific exchangers or chelating sorbents are a subgroup of ion exchange resins. Chelating resins were developed to obtain higher selectivities of at least one particular counter-ion species. The interaction ofa functional group(ligand) of chelating resin and metal(in form of cation or oxoanion) is selective with respect to the nature of the metal.

Product Details

Chelating resins are a class of ion exchange resins. They are almost always used to bind cations. They utilize chelating agents covalently attached to a polymer matrix. They have the same bead form and polymer matrix as usual ion exchangers. Their main use is for preconcentration of metal ions in a dilute solution.


They has a functional group that is capable of forming a chelate (complex) with a metal ion. The specific metals that can form chelates with the functional group can be captured. In this series, there are five product models. Below is basic information of one of these product:


CH010

Used for mercury removal, precious metals recovery


It has weakly acidic thiourea (-CH2-S-C-NHNH2) on the styrene / DVB copolymer with special macroporous structure. This product can fix and chelating one or several kinds of certain cation in a great range even in the solution with high content. It is used mainly to separate and purify the free mercury and precious metals, with the characteristics such as uniform grain and good mechanical intensity.
