Me pēhea te whakamātautau i te tāpiritanga o ngā matū kore-waro ki ngā āwhina tukatuka ACR?

Tikanga kimi mō te Ca2+:

Ngā taputapu whakamātautau me ngā matū whakamātau: ngā ipurau; te pounamu kōniko; te kōrere; te pūrete; te oumu hiko; te etanoru waikore; te waikawa hauwaiora, te wairewa parepare NH3-NH4Cl, te tohu konupūmā, te wairewa paerewa 0.02mol/LEDTA.

Ngā taahiraa whakamātautau:
1. Paunatia kia tika te nui o te tauira āwhina tukatuka ACR (kia tika ki te 0.0001g) ka whakanoho ki roto i te ipurau. Whakamakukuhia ki te etanoru waikore, kātahi ka tāpirihia he waikawa hauwaiora 1:1 te nui rawa, ka whakamahana ki runga i te oumu hiko kia taea ai e ngā katote konupūmā te tauhohe katoa ki te waikawa hauwaiora;
2. Horoia ki te wai, ka tātarihia ki te tauera kia puta ai tōna wai mārama;
3. Whakatikatikahia te uara pH kia neke atu i te 12 mā te whakamahi i te otinga parepare NH3-NH4Cl, tāpirihia he nui e tika ana o te tohu konupūmā, ka titrate ki te otinga paerewa 0.02mol/LEDTA. Ko te mutunga ko te wā e huri ai te tae mai i te papura whero ki te kikorangi parakore;
4. Whakahaerehia he whakamātautau pātea i te wā kotahi;
5. Tātaihia C # a2+=0.02 $(V-V0) $0.04004M $%&&
V – Te nui o te otinga EDTA i pau i te whakamātautau i ngā tauira āwhina tukatuka ACR (mL).
V # – Te rōrahi o te otinga i pau i te wā whakamātautau pātea
M — Paunatia te taumaha o te tauira āwhina tukatuka ACR (g).

Te tikanga tahu mō te ine i ngā matū kore-waro:
Ngā taputapu whakamātautau: taurite tātari, oumu whakakā.
Ngā mahi whakamātautau: Tangohia he tauira āwhina tukatuka ACR 0.5,1.0 karamu (tika ki te 0.001 karamu), whakanohoia ki roto i te oumu whakamahana pāmahana pumau 950 ka tahu mō te 1 hāora, kātahi ka whakamatao ka paunatia hei tatau i te toenga o te rauemi kua tahuna. Mēnā ka tāpirihia he matū kore-waro ki te tauira o ngā āwhina tukatuka ACR, ka nui ake ngā toenga.
Tikanga whakarewa:
1. Ngā taputapu whakamātautau me te taurite tātari matū; pounamu rōrahi 25mL; Trichloromethane.
Hipanga 2: E ai ki te tikanga whakamātautau matotoru ā-roto ACR, paunatia te 75mg o te tauira ka whakanoho ki roto i tētahi pounamu rōrahi 25mL. Tāpirihia he whakarewa trichloromethane. Mena he pōuri, he mārama kitea rānei.
