Embodiment

[0063] Weigh 0.1000g of pure gold with a purity ≥ 99.9%, put it in a 50mL beaker, add 5mL of aqua regia, heat to completely dissolve the pure gold, evaporate to near dryness, then add 10mL of 10% hydrochloric acid to dissolve, and then transfer to 500mL In a volumetric flask, dilute to the mark with water, and mix well to obtain the first gold standard solution containing 0.2 mg of gold per milliliter of solution; pipette 20.00 mL of the first gold standard solution, place it in a 200 mL volumetric flask, and add a concentration of 10 % hydrochloric acid 10mL, dilute to the mark with water, and mix well to obtain the second gold standard solution containing 20μg of gold per milliliter of solution; take six separating funnels with a volume of 125mL, and add a concentration of 15mL of 10% hydrochloric acid, then add 0.00mL of the second gold standard solution to the first separating funnel, add 1.00mL of the second gold standard solution to the second separating funnel, and add 2...

Abstract

The invention discloses a measurement method for gold content of anode copper. The measurement method comprises the following steps of: drawing a series of working curves of a standard solution; putting an anode copper sample of which the gold content is to be measured into aqua regia and heating to dissolve; adding methyl isobutyl ketone to extract the gold from a solution; measuring the absorbance of the solution where the anode copper sample is dissolved in an organic phase by using an atomic absorption spectrophotometer; and calculating the gold content of the anode copper sample according to the absorbance and the series of working curves of the standard solution. With the adoption of the measurement method, the time is save, and the cost for personnel is lowered; meanwhile, a high-temperature operating environment is avoided, so that the operation is fast, easy to grasp and suitable for the analysis of mass production; and the analytic measurement result is accurate and reliable, the measurement method is suitable for the simultaneous measurement of a plurality of samples, the cost for analysis is saved, and the practicability is strong.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and relates to a method for determining the content of other elements in anode copper, in particular to a method for determining the content of gold in anode copper. Background technique [0002] The gold content in the anode copper is usually determined by the fire assay gold method. The method is cumbersome, difficult to operate, and the analysis period is long, so it is not suitable for mass production. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the object of the present invention is to provide a method for determining the gold content in anode copper, which is quick to operate, saves time and effort, and is suitable for mass production. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is, a method for measuring gold content in anode copper, draw a series of...
