D201 Macroporous Styrene series strongly alkaline anion exchange resin

This product is similar to 201×7 Strong-Base Type I (Gel) Anion Exchange Resin, but provided with better physical and chemical stability. It has strong capabilities of permeation resistance, abrasion resistance and contamination resistance. For it has macroporous structure, and can exchange big-sized ions and molecules, so it can be used in non-aqueous medium.
They are mainly used in manufacture and purification of pure water and high purity water, decolorization of sugar solution and fermentation solution, wastewater treatment, adsorption and extraction of vanadium pentoxide, recycling of heavy metal etc.
