| 摘要: |
| 通过对几种树脂比较后发现,在氯化溶液中353E树脂对金是一种较为理想的吸附剂。考察了溶液中金含量、酸度、氯离子浓度等因素对353E树脂吸附金的影响,酸度、硫脲浓度、温度等对硫脲解吸金的影响。在适宜条件下,金的吸附率和解吸率都在98%以上。 |

| Abstract: |
| It was found that 353E resin was an ideal adsorbent for gold in chloride solutions after comparing several resins. The effects of gold content in solution,acidity and chloride concentration on the adsorption,and the effects of acidity,thiourea concentration and temperature on the desorption were examined.Both the adsorption rate and the desorption rate of gold could reach over 98% under suitable conditions. |
