摘　　要：载金炭中金含量较高,通常采用火试金重量法测定,但是该方法存在检测成本高,方法操作复杂等劣势,对于部分企业并不适用。本实验采用焙烧溶样-活性炭吸附-分取-氢醌滴定的方法来测定载金炭中的金含量,该方法有快速,易操作,成本较低且准确度较高的优点,适合该回收厂载金炭产品金含量检测,该方法对其他化验检测单位具有借鉴意义。The content of gold in gold-loaded Carbon is relatively high,and it is usually determined by fire assay gravimetric method.However,this method has the disadvantages of high detection cost and complicated operation,and is not applicable to some enterprises.In this experiment,the method of roasting dissolved samples-activated carbon adsorption-separation and hydroquinone titration was used to determine the content of gold in thegold-loaded Carbon.This method has the advantages of fast,easy operation,low cost and high accuracy,and is suitable for the detection of gold content in the gold-loaded Carbon products of the recycling plant.This method is of reference significance to other laboratory units.
