Ion-exchange resin to think about in the course of preprocessing:

1, ion-exchange resin containing some water, not suitable for open storage, and through storage and transportation need to be kept moist to avoid dry dehydrated, so resin broken, resin dehydration such as storage, you'll want to use sturdy salt water (10%) soak, then gradually diluted, in place of straight into the water, so as to prevent resin swelling and broken.
2, winter storage and transport use, needs to be kept at temperature 5-40 ??, steer clear of extreme cold or heat, influence the top quality, if in winter when there's no insulation equipment, resin is often stored in salt water in the salt water concentration may be determined in accordance using the temperature.
Strong Acid Cation Exchange Resin
three, and ion exchange resins of industrial items within the, often contains couple of low polymer and not take part in reaction of monomer, also includes iron, and lead, and copper, inorganic impurities, dang resin and water, and acid, and alkali or other answer get in touch with Shi, above material on will into answer inside the, effects water excellent, so, new resin in working with Qian ought to for pretreatment, Common 1st water tends to make resin full expansion, then, on which of inorganic impurities (principal is iron of compounds) available hovers of diluted hydrochloric acid removed, organic impurities accessible 2-4% Dilute aqueous sodium hydroxide to take away, wash to near-neutral. As in preparation of pharmaceutical use, shall be treated with ethanol.
four, and resin in working with within the, protect against and metal (as iron, and copper,) oil, and organic molecular microbial, and powerful oxidation agent, make contact with, from makes ion exchange capacity reduced, even lost function, so, should as outlined by situation on resin for not often of activation processing, activation process can as outlined by pollution predicament and conditions and set, General Yang resin in softening in the quick by Fe of pollution accessible hydrochloride soaking, then steadily diluted, Yin resin uncomplicated by organic pollution, obtainable 10%NaC1 2-5%NaOH mixed answer soaking or leaching, 1% hydrogen peroxide option soak to get a handful of minutes, if necessary, other, acid-base alternating treatment techniques may well be employed, bleaching therapy, alcohol treatment and sterilization procedures, and so on.
five, the new pretreatment of resin: ion exchange resins for industrial solutions, usually with small amounts did not participate in the reaction from the monomer and oligomer, also include inorganic impurities for instance iron, lead and copper. When the resin with water, acids, alkalis, or some other option when option of diversion of those substances will influence water top quality. Thus, new resins has to be pretreated just before use. Usually water resin to expand, then, of inorganic impurities (mainly iron compounds) offered billion-plus dilute hydrochloric acid to remove, 2-4% accessible in dilute sodium hydroxide resolution to eliminate organic impurities could be washed into near-neutral.
