Habka Falanqaynta Waxyaalaha Palladium ee ku jira Xakamaynta Palladium

1. Abstract
Kobcinta palladium ee kicinta palladium ee pyrometallurgy, ka dibna ku milmi palladium ee aashitada admixture, dareeraha waxaa falanqeeyay AAS.
2. Reagent
2.1 Hydrochloric acid (ρ1.19g/ml)
2.2 Nitric acid (ρ1.42g/ml)
2.3 Admixture acid (Hydrochloric acid iyo Nitric acid isku qasan, mugga sida 3:1)
2.4 Perchloric acid (AR)
2.5 Sodium chloride xal (50g/L)
2.6 Xalka caadiga ah ee palladium:
Miisaanka 0.1g palladium (laga soo saaro 0.0001g), kaas oo si buuxda ugu milmay 40mL aashitada admixture by kulayl yar.Ku dar 5mL sodium chloride xalkii hore, uumi si aad ugu dhowaato engegan, ka dibna ku dar 3mL hydrochloric acid, uumiga ku dhawaad ​​engegan, ku celi labada tallaabo saddex jeer.Ku dar 10mL hydrochloric acid, u beddel dhalada awoodda, ku milo miisaanka, isku walaaq si isku mid ah, maadada palladium ee xalka waa 1.0mg/mL.
3. Qalabka
3.1 AAS, Olol, nooca gaaska: acetylene-hawo.Halbeegyada waxaa loo dejiyey si waafaqsan diiwaanka buug-karinta.
3.2 Qalabka shaybaadhka caadiga ah.
4. Tusaalaha la tuuro
Dhig 0.15g (sida saxda ah 0.0001g) ee muunada ay tuurtay pyrometallurgy 100mL beaker, samee laba muunado is barbar socda.Ku dar aashitada admixture 15mL, dhanka kale ku dar 5mL perchloric acid, ku milmi kulayl, uumi si aad u qallajiso, ku dar 5mL sodium chloride solution, ka dibna ku dar 3mL hydrochloric acid, uumi si aad u qallajiso, ku celi labada tallaabo saddex jeer.Ku dar 10mL hydrochloric acid, u beddel dhalada awooda, milo miisaanka, si isku mid ah ugu walaaq, waxa ku jira palladium ee xalka muunada qiyaastii waa 1.5mg/ml Si loo cabbiro, waxa ku jira palladium ee xalka muunada qiyaastii waa 0.15mg/mL.
5. Go'aaminta nuxurka
5.1 Codso xalalka caadiga ah ee ka kooban AAS oo samee qalooca caadiga ah (xalka caadiga ah 2,4,6,8,10ppm), go'aami nuugista muunada, ka dibna xisaabi xoojinta muunada iyadoo la raacayo qalooca caadiga ah.
