Macroporous Adsorption Resin AB-8 - Hebei Lijiang Biotechnology Co., Ltd.|Water Purification, Separation & Purification

Introduction

Discover the Macroporous Adsorption Resin AB-8, a high-performance adsorbent developed by Hebei Lijiang Biotechnology Co., Ltd.. This resin is engineered for efficient extraction, separation, and purification of water-soluble and weakly polar compounds.

Product Features

• Milky white or light yellow appearance for easy observation during processing.
• Stable physical and chemical properties, insoluble in acids, alkalis, or organic solvents.
• High selectivity for organic matter, unaffected by inorganic salts.
• Easy regeneration using ethanol, water, or dilute acids/bases.

Technical Specifications

Parameter	Specification
Appearance	Milky white opaque spherical beads
Pore Volume	0.73–0.77 ml/g
Specific Surface Area	≥480 m²/g

Applications

AB-8 resin is ideal for water purification, pharmaceuticals, and food processing. It excels in isolating compounds like stevioside and alkaloids.

Preparation and Regeneration

Pretreatment

Soak in ethanol (10–20 cm) for 3–4 hours, then rinse with water until neutral.

Enhanced Regeneration

Use 3–5% HCl for 2–4 hours, followed by 5% NaOH. Rinse thoroughly to restore adsorption capacity.

Precautions

• Store at 5–40°C to prevent freezing or mildew.
• Avoid direct water injection if resin dries; use ethanol to rehydrate.
