| Abstract: | Established a nitric acid,hydrochloric acid,hydrofluoric acid and aqua regia as a solvent,using microwave digestion and inductively coupled plasma as Steel Tin,Copper,Lead,Antimony,arsenic and other trace elements measurement.Experiments examined different digestion acid,thermometer time on resolving the impact effect.The results showed that the pressure is 1.52MPa,temperature 200 ℃,using 3mL of hydrochloric acid,1mL 1mL of nitric acid and hydrofluoric acid composition of the mixture can be of steel in the As,Pb,Sb,Sn,Cu and completely remove it;At the same time,through the RF power,sampling depth,the gas flow,so as to reduce the signal drift,the impact of the experimental study. |
