D755 is macroporous polystyrene chelating resin with thiourea group ,it is mainly used for selective removal of heavy metal ions in solution, especially for mercury, gold, platinum, palladium and other noble metal ions.D755 is suitable for extracting mercury ions from different solutions, and can reduce the mercury content to less than 5ppb.The resin can also be used in different chemical industries, such as recovering precious metals from waste water from the electronics industry.
D760 is a selective ion exchange resin for removing boron and its salts from aqueous solution.Macroporous structure chelating resin with N- methyl glucosamine and complex anion formed between polyvalent alcohol base and boron，The amine part conduct anion exchange group to form complex anion, thus the adsorption of borate ion is selected.The resin is not affected by salt substances and is strictly required for PH. Complex ions can be formed only in neutral or alkaline solutions, and complex ions are decomposed in acid solutions.
D113 is a premium grade, weak acid, macroporous, cation resin supplied in the hydrogen form as moist, tough, uniform, spherical beads. Its ion exchange functionality is derived from the carboxylic group, which is easily converted to the hydrogen form and has a high affinity for divalent ions.D113 is intended for use in hydrogen cycle dealkalization, deionization, and chemical processing applications. D113 can also be supplied in the sodium form for use in sodium cycle applications such as softening and removal of heavy metal cations.
D111 This is a kind of cation exchange resin which has carboxylic acid groups [-COOH] in the macroporos acrylic acid-divinylbenzene copolymer. It works with large exchange capacity, speedy exchange ability, small volumn change, good physical strength and chemical stability, excellent capabilities of contamination and oxidation resistance etc.
This is a kingd of cation exchange resin which has carboxylic acid groups [-COOH] in the phenolic aldehyde copolymer.
