| titleOfInvention | Au plasma enrichment method in a kind of soil |
| abstract | The invention discloses Au plasma enrichment methods in a kind of soil, include the following steps: S1: weighing sample, calcination is transferred in container after cooling；S2: the Fe of 1:1 chloroazotic acid and 95-120g/L is added in the container of step S1 3+ Solution, chloroazotic acid and Fe 3+ The volume ratio of solution is 45-60:1, ebuillition of heated 1.5-3h；Heating evaporation is concentrated into acidity in 5%-10%, is diluted with water Cheng Yici extracting solution, spare；S3: being added foamed plastics in an extracting solution of step S2, shakes 45-90min；S4: taking out foamed plastics, washes with water clean, drying；S5: the foamed plastics in step S4 is put into container, and the thiourea solution that concentration is 10-12g/L is added in a reservoir, places a limiter in a reservoir thus by the position restriction of foamed plastics below the liquid level of thiourea solution；It is covered in the opening of container, container is heated into 30-60min in boiling water bath；Constant volume obtains concentrated extracting solution after taking out foamed plastics while hot.Has the effect of improving extracted amount to improve test accuracy. |
