Hanyar Yin Nazari Abun Ciki na Palladium A cikin Palladium Catalysts

1. Abstract
Ingantattun palladium na palladium masu haɓakawa ta hanyar pyrometallurgy, sannan narkar da palladium a cikin admixture acid, AAS na nazarin ruwa.
2. Reagent
2.1 Hydrochloric acid (ρ1.19g/ml)
2.2 Nitric acid (ρ1.42g/ml)
2.3 Admixture acid (Hydrochloric acid da Nitric acid gauraye, juzu'i kamar 3:1)
2.4 Perchloric acid (AR)
2.5 Sodium chloride bayani (50g/L)
2.6 Daidaitaccen bayani na palladium:
Auna 0.1g palladium (cire zuwa 0.0001g), wanda aka narkar da shi gaba daya a cikin 40mL admixture acid da ƙananan zafi.A zuba 5mL sodium chloride bayani a cikin tsohon maganin, a zubar da shi ya kusan bushe, sannan a zuba 3mL hydrochloric acid, a zubar da shi ya kusan bushe, maimaita matakai biyu sau uku.Ƙara 10mL hydrochloric acid, canza cikin kwalban iya aiki, tsarma zuwa sikelin, haxa shi daidai, abun ciki na palladium a cikin maganin shine 1.0mg / ml.
3. Na'ura
3.1 AAS, harshen wuta, irin gas: acetylene-iska.An saita sigogi bisa ga rikodin littafin dafa abinci.
3.2 Na'urar Lab na gama gari.
4. Samfurin zubar da ciki
Sanya 0.15g (daidai zuwa 0.0001g) na samfurin da aka zubar ta hanyar pyrometallurgy a cikin 100mL beaker, yi samfurori guda biyu.Sai a zuba 15mL admixture acid, sai a zuba perchloric acid 5mL, sai a narkar da shi da zafi, a zubar da shi ya kusa bushewa, sai a zuba sodium chloride 5mL, sannan a zuba 3mL hydrochloric acid, sai a zubar da shi ya kusan bushe, a maimaita matakai biyu sau uku.Ƙara 10mL hydrochloric acid, canzawa cikin kwalban iya aiki, tsarma zuwa sikelin, haxa shi daidai, abun ciki na palladium a cikin maganin samfurin kusan shine 1.5mg / ml, canza 10mL na maganin samfurin a cikin kwalban ƙarfin 100mL, ƙara 3mL hydrochloric acid, dilute don sikelin, abun ciki na palladium a cikin samfurin samfurin kusan shine 0.15mg/mL.
5. Tabbatar da abun ciki
5.1 Aiwatar da ƙayyadaddun ƙayyadaddun bayani a cikin AAS kuma yin daidaitaccen tsari (madaidaicin bayani 2,4,6,8,10ppm), ƙayyade ɗaukar samfurin, sannan ƙididdige ƙaddamar da samfurin bisa ga daidaitaccen lanƙwasa.
