Model AMP -Weakly Basic Macroporous Anion Exchanger
AMP anion exchanger - weakly basic macroporous resin with a styrene-divinylbenzene matrix. Manufactured specifically for extracting rhenium from acidic solutions or slurries in hydrometallurgical processes ore processing, spent multicomponent refractory alloys and catalysts. It exhibits a high selectivity rhenium, has excellent mechanical, osmotic and thermal stability.
AMR anion exchange resin is produced according to TU U 20.1-30168850-058: 2019
Recommendations for use - the concentration of the rhenium or molybdenum in the starting solution can range from 1 to 1000 ppm, the sulfuric acid concentration of from 5 to 500 g / l. Before the adsorption step is recommended to convert AMP anion exchanger completely or partially in sulphate form. Desorption of rhenium and molybdenum recommended 5-25% aqueous solution of ammonia. Thus from desorbate rhenium can be isolated directly in the form of ammonium perrhenate - the most common marketable forms of rhenium.
Packaging - anion exchanger packed in polypropylene bags with a liner made of polyethylene film. The weight of the anion exchanger in the bag 35 - 0.35 kg.
It is transported It in Covered vehicles in Accordance with the The Rules for the carriage of goods in force on the this of the type of transport.
Shelf life - 2 years from the date of manufacture.
Analogue anion AMP is Purolite A-170
