采用无氰化钠的解吸液，用有机试剂蒸汽解吸法进行了载金炭解吸的研究。实验中选择了（Ⅰ）、（Ⅱ）两种体系，分别探讨了有机试剂浓度、ＮａＯＨ浓度、Ｎａ＿２ＣＯ＿３浓度，解吸时间及水质等因素对解吸率的影响，并初步进行了活性炭活性试验，研究发现，采用（Ⅰ）体系和（Ⅱ）体系可使载金炭解吸率分别达到９９．４％和９９．７％。贫炭品位降至２０ｇ／ｔ以下，水质时解吸几乎没影响，解吸后贫炭经水蒸汽热再生后活性仍然很强，采用该法不仅提高了解吸率，而且显著缩短解吸时间，降低成本，改善工作环境，减少环境污染。
Using desorption solution without sodium cyanide, desorption of gold by carbon was studied by vapor desorption of organic reagents. The effects of organic reagent concentration, NaOH concentration, Na_2CO_3 concentration, desorption time and water quality on the desorption rate were investigated respectively. The activity of activated carbon was preliminarily studied. It was found that the two systems (Ⅰ, Ⅱ) , The desorption rate of gold-loaded carbon can reach 99.4% and 99.7% respectively using (I) system and (II) system. Lean charcoal reduced to less than 20g / t, almost no effect on desorption when water quality. After desorption, the activity of lean charcoal after steam regeneration by steam is still very strong. By this method, not only the desorption rate is increased, but also the desorption time is significantly shortened, Improve the working environment and reduce environmental pollution.
