Company Background

Hebei Lijiang Biotechnology Co., Ltd. is a leading manufacturer of advanced materials, specializing in the development of macroporous adsorption resins and related products. With a focus on innovation and quality, the company provides solutions that meet the demands of modern industries. Their commitment to research and development ensures that their products, such as the AB-8 resin, adhere to the highest standards of performance and reliability.

Pretreatment and Regeneration

Before use, the resin requires proper pretreatment to ensure optimal performance:

• Pretreatment: Soak the resin in ethanol for 3–4 hours, then rinse thoroughly with water until no ethanol odor remains.
• Enhanced Regeneration: For heavily contaminated resins, treat with hydrochloric acid (3–5%) and sodium hydroxide (5%) solutions, followed by thorough rinsing with water to neutralize pH.

Precautions

• Store the resin at 5–40°C to prevent freezing or mold growth.
• Avoid direct water injection if the resin dries out; instead, rehydrate with ethanol before rinsing.
• Filter solutions before use to prevent impurities from clogging the resin column.
• Store the resin in clean water or saturated saline/ethanol after use to maintain its integrity.
