Abstract
A process for the recovery of tellurium compounds which have been retained on a strongly acidic sulfonated ion exchange resin employed to remove soluble tellurium compounds from tellurium-containing vicinal glycol ester solutions, by elution of the resin with dilute mineral acids, such as hydrochloric, to form a tellurium-containing acid eluate and treating the eluate by stripping or distilling to remove contained water and acid leaving a tellurium compound concentrate which may be treated in the presence of air or oxygen to convert the tellurium to a form suitable for reuse in the preparation of vicinal glycol esters.
