Abstract
Systems and methods for separation and purification of chemicals using ion-exchange resins are provided.
Claims12
A method, the method comprising extracting a product from a liquid process sample or waste sample, wherein the extracting comprises:
- a liquid fill step, wherein the liquid is delivered into a first column (C1) comprising a strong acid cationic resin;
- a water rinse step, wherein water is passed through C1;
- a heptane rinse step, wherein heptane is passed through C1;
- an elution step, wherein diethylamine (DEA) in heptane is passed through C1;
- a second heptane rinse step, wherein heptane is passed through C1 to form an extracted product solution;
- and a recirculation step, wherein the extracted product solution is recirculated through C1.
A system for the extraction of a product from a process sample or waste sample, the system comprising an extraction column comprising a strong acid cationic resin.
A method, the method comprising extracting a product or contaminant from a liquid process sample or waste sample, by first converting the product or contaminant to an acid, wherein the product or contaminant is converted to an acid using an ion exchange resin comprising a strong acid resin.
