Preparation and Regeneration Proper preparation and regeneration are critical for maximizing the resin's efficiency. Here’s a step-by-step guide: Resin Pretreatment Soak the resin in 10–20 cm of ethanol for 3–4 hours. Drain the solution and repeat washing until the effluent is clear. Rinse with clean water until no ethanol odor remains. Enhanced Regeneration Soak in 3–5% hydrochloric acid for 2–4 hours. Rinse with 5–7 times the volume of the acid solution until neutral pH. Repeat the process with 5% sodium hydroxide solution. Final rinse with water until the effluent is neutral. For detailed instructions, refer to the product documentation . Precautions for Optimal Performance To ensure the resin's longevity and effectiveness, follow these guidelines: Store the resin at 5–40°C to prevent freezing or mold growth. Avoid direct water contact if the resin is dry; use ethanol to rehydrate it first. Filter the solution before loading to prevent resin poisoning. Store the resin in clean water or saturated saline/ethanol for long-term use. About Hebei Lijiang Biotechnology Co., Ltd. Hebei Lijiang Biotechnology Co., Ltd.
