D280U is a sort of anion exchange resin that has quaternary ammonium group [-N(CH3)3OH] in the cinnamene styrene and diethenoid benzene copolymer with macroporous structure. It is used mainly to absorb and enrich and purify uranium in the uranium mine and its waste water, enrich and separate thorium and plutonium and uranium in the nuclear industry, treat and recover vanadium in the waste water produced in ammonia synthesizing, separate and remove zinc in the nickel electrolyte.

D382 is a sort of anion exchange resin that has tertiary amine group [-N(CH₃)₂] in the cinnamene styrene and diethenoid benzene copolymer with macroporous structure. It is used mainly to enrich and extract uranium in the uranium mine solution, separate and remove plumbum in the nickel and cobalt electrolyte, with uniform grain size distribution.

D751chelating ion-exchange resin is cross-linked polystyrene copolymer structure, the introduction of iminodiacetic acid functional group of the weak acid macroporous cation exchange resin, The selectivity of metal ions similar to EDTA, to remove it from the aqueous solution of divalent cations in order of preference is as follows: Cu2+﹥VO2+﹥UO22+﹥Pb2+﹥Ni2+﹥Zn2+﹥Cd2+﹥Fe2+﹥Be2+﹥Mn2+﹥Ca2+﹥Mg2+﹥Sr2+﹥Ba2+﹥Na+

Can be seen from the previous, D751 chelating resin demonstrated two divalent metal ions with high selectivity and high affinity. At the same time have been exchanged divalent metal ions in the low PH of the solution is easy to desorption (regeneration) so that chelation group restore exchange adsorption capabilities.

D750 is a chelating resin with weak acid imide two acetic acid [-CH₂N-(CH₂OOH)₂] on the special macroporous structure of styrene and two ethylene benzene copolymers.It can immobilize and chelate one or more specific cations in a large range or even from a high concentration solution.

D752 is a special strong alkali anion resin, which is mainly used to remove nitrate from aqueous solution，especially groundwater and fish and shrimp aquaculture.The resin has a special skeleton and three ethylamine functional groups, and has a very high selectivity for nitrate.The resin has high exchange capacity, stronger wear resistance and physical stability.

D753 is a chelating resin specially designed for removal of high arsenic in drinking water.The resin can effectively adsorb trivalent arsenic and pentvalent arsenic in water by carrying iron oxide and has high adsorption capacity.Through adsorption of resin, arsenic content in water can be effectively reduced to drinking water safety level.This resin can be continuously regenerated and can maintain a long working cycle. The economic benefit is very high. Because of its unique chemical characteristics, it can be used in neutral and alkaline environments.
