If you operate a plant—or you’re just the person everyone calls when the TOC spikes—you’ve probably looked into water purification resin more times than you’d admit. Lately I’ve been tracking a quiet shift in the market: facilities are leaning into macroporous adsorption media not just for polishing wastewater, but for value recovery from botanicals and fine chemicals. One of the names that keeps popping up in my inbox: Macroporous Adsorption Resin AD-101.
AD-101 is a non‑polar styrene–divinylbenzene (DVB) macroporous adsorbent. The porogens (toluene and octanol) create a sponge-like network that loves non‑polar or weakly polar organics—phenolics, pesticides, PAHs, even stubborn color bodies. It’s also known in pharma/herbal circles for saponins, flavonoids, and alkaloids (ginsenosides, notoginseng saponins, diosgenin, ginkgo flavones). In short: it bridges industrial cleanup and high‑value separations. Honestly, that’s rare.
| Matrix | Styrene–DVB, non‑polar |
| Particle size | ≈ 0.3–1.2 mm (real-world use may vary) |
| BET surface area | ≈ 350–700 m²/g |
| Average pore diameter | ≈ 10–20 nm |
| Moisture content | 50–65% |
| Bulk density | ≈ 0.60–0.70 g/mL |
| Operating pH | 1–14 (adsorption performance varies by solute) |
| Max wet temperature | ≈ 120°C |
| Typical capacity | Phenol 120–200 mg/g; saponins 180–250 mg/g (lab data) |
| Service life | 800–1500 cycles with proper regeneration |
Manufacturer location: NO.2 East Jianshe Road, High-Tech Industrial Development South Zone, Wei County, Xingtai, Hebei, China.
| Vendor | Resin Type | Target Organics | Indicative Price | Certs/Notes |
|---|---|---|---|---|
| AD-101 (Lijiresin) | Styrene–DVB macroporous | Saponins, phenolics, color bodies | Mid-range (≈$8–$15/kg) | ISO-style QA; NSF/food-contact on request |
| Vendor A (global) | High-porosity styrene–DVB | PAHs, pesticides | Premium (≈$18–$28/kg) | NSF/ANSI 61-listed SKUs |
| Vendor B (regional) | Acrylic-based adsorbent | Polar organics, dyes | Budget (≈$6–$10/kg) | Limited export docs |
Estimated; confirm with suppliers. Real-world use may vary.
Customization: particle size windows, moisture spec, and pre-conditioning (ethanol-wet) are usually available. For potable or food-adjacent uses, ask for NSF/ANSI 61 or equivalent migration testing, plus a statement on FDA/food-contact applicability. Also, request a QA pack: CoA, SDS, and batch D2187-style physicals.
