Abstract
The present invention provides a kind of inspection iron method of noble metal in solution, comprises the concrete steps that: solution 5ml exchange is extracted in clean 60ml separatory funnel, addition hydrochloric acid, and standing；After disappearance of generating heat, ethyl acetate is added, sufficiently vibrates one minute, is static to its layering, it is careful to release solution of the lower layer containing noble metal；The hydrochloric acid of addition sufficiently vibrates, static layering, releases lower layer's solution；Lower layer's solution is taken, KCNS is finally instilled, sees that its colour developing degree and standard colorimetric plate compare, judges the content height of iron in solution.The present invention can clearly exchange the bullion content in solution by the judgement of certificate test, and the exchange degree of noble metal in solution is judged with this；This method simple process, it is convenient to operate, and effectively improves waste water utilization rate, improves the recovery efficiency of noble metal.
Description
Technical field
The present invention relates to a kind of inspection iron methods, and in particular to the inspection iron method of noble metal in solution.
Background technique
In recent years, with the increasingly raising of Environmental costs, environmentally protective noble metal collector becomes the emphasis of people's research.
It is a kind of using magnetic material, iron powder, iron ore or ferriferous oxide as trapping agent, with noble metal materials, additive and reducing agent ball
Nodulizing is restored to obtain pelletizing containing precious metal alloys under protective atmosphere, then removes base metal through ball milling, acidleach, is obtained expensive
Metal enrichment effect is poor, and mill choosing then causes noble metal dispersion in slag, causes the noble metal rate of recovery low, and energy consumption is high.Your existing gold
The problems such as there are heavy metal pollution, material consumption energy consumption height, metallurgical waste discharge amounts for category extraction process greatly, noble metal recovery rate is low.Needle
Processing to recycling solution, general degree for the treatment of are all that permanent micro-judgment is leaned on to complete, and can not really accomplish recycling most
Big degree, to result in waste of resources.
Summary of the invention
For above situation, the inspection iron method that the purpose of the present invention is to provide a kind of in platinum catalyst network production process,
The recycling degree of noble metal is demarcated.
To achieve the above object, the technical solution used in the present invention is: providing a kind of inspection iron side of noble metal in solution
Method, the specific steps of which are as follows:
(1) it prepares solution: extracting the solution 5ml exchanged in clean 60ml separatory funnel, 5ml hydrochloric acid is added, stand；
(2) after disappearance of generating heat, the ethyl acetate of 10ml is added, sufficiently vibrates one minute, is static to its layering, under careful releasing
Solution of the layer containing noble metal；
(3) hydrochloric acid of 10ml 1:1 is added, is sufficiently vibrated, static layering, lower layer's solution is released；
(4) lower layer's solution is taken, the KCNS of 20 drops 10% is finally instilled, sees that its colour developing degree and standard colorimetric plate compare, judge solution
The content of middle iron height.
Principle: thiocyanometry liquid can be used for examining and determine ferric iron, copper and noble metal；Thiocyanate salt solution titrates trivalent
Iron ion blood is red, and precious metal ion colour developing is Chinese red, by comparing the degree of colour developing and standard colorimetric plate, can be used to sentence
The content of disconnected metal.
The standard limit value of the tenor is 0.007%.
The beneficial effects of the present invention are: the bullion content in solution can clearly be exchanged by the judgement of certificate test,
The exchange degree of noble metal in solution is judged with this；This method simple process, it is convenient to operate, and effectively improves waste water utilization rate, mentions
The recovery efficiency of high noble metal.
Specific embodiment
The application is illustrated by the following examples.
The application is illustrated by the following examples, the inspection iron method of noble metal, specific steps in a kind of solution
It is as follows:
(1) it prepares solution: extracting the solution 5ml exchanged in clean 60ml separatory funnel, 5ml hydrochloric acid is added, stand；
(2) after disappearance of generating heat, the ethyl acetate of 10ml is added, sufficiently vibrates one minute, is static to its layering, under careful releasing
Solution of the layer containing noble metal；
(3) hydrochloric acid of 10ml 1:1 is added, is sufficiently vibrated, static layering, lower layer's solution is released；
(4) lower layer's solution is taken, the KCNS for finally instilling 20 drops 10% judges its color for Chinese red.
By the way that there are precious metal elements in waste liquid handled known to the color of judgement reaction, waste water is purified and is located again
Reason is not Chinese red until reaction measures color, is obtained at this time by measurement, and tenor is lower than 0.007%.
Claims (2)
1. the inspection iron method of noble metal in solution, the specific steps of which are as follows:
(1) it prepares solution: extracting the solution 5ml exchanged in clean 60ml separatory funnel, 5ml hydrochloric acid is added, stand；
(2) after disappearance of generating heat, the ethyl acetate of 10ml is added, sufficiently vibrates one minute, is static to its layering, under careful releasing
Solution of the layer containing noble metal；
(3) hydrochloric acid of 10ml 1:1 is added, is sufficiently vibrated, static layering, lower layer's solution is released；
(4) lower layer's solution is taken, the KCNS of 20 drops 10% is finally instilled, sees that its colour developing degree and standard colorimetric plate compare, judge solution
The content of middle iron height.
2. the inspection iron method of noble metal in solution according to claim 1, it is characterised in that: the standard of the tenor
Limit value is 0.007%.
