Desorption ： "Resin adsorption of gold thiourea with 9% + 3% sulfuric acid analysis, analytical dosage of 6-8 times the bed volume, contact time with Resin for 2h or more.
"
Regeneration process： Resin after resolution after washing, rinse with 2-3 times the bed volumeNaOH, about 1 hour, then rinse renewable HCl solution, the dosage is 2 times the bed volume, time is about 1.5h, washed clean and odor can be the last.
