Me pēhea te whakamātautau i te tāpiritanga o ngā matū kore-waro

Me pēhea te whakamātautau i te tāpiri o ngā matū kore-waro ki ngā āwhina tukatuka ACR：

Tikanga kimi mō te Ca2+:

Ngā taputapu whakamātautau me ngā matū whakamātau: te pīkara; te pounamu āhua-kone; te kōrere; te pūretē; te oumu hiko; te etanoru waikore; te waikawa hauwaiora, te otinga parepare NH3-NH4Cl, te tohu konupūmā, te otinga paerewa EDTA 0.02mol/L.

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 te waikawa hauwaiora 1:1 nui rawa, ka whakamahana ki runga i te oumu hiko kia tino tauhohe ngā katote konupūmā ki te waikawa hauwaiora;

2. Horoia ki te wai, ka tātari mā te kōrere kia puta ai te wai mārama;

3. Whakatikatikahia te uara pH kia neke atu i te 12 me te otinga parepare NH3-NH4Cl, tāpirihia he nui e tika ana o te tohu konupūmā, ka titrate ki te otinga paerewa EDTA 0.02mol/L. Ko te mutunga ko te wā e huri ai te tae mai i te papura whero ki te kikorangi parakore;

4. Whakahaerehia ngā whakamātautau kau i te wā kotahi;

5. Tātaihia C # a2+=0.02 $(V-V0) $0.04004M $%&&

V – Te rōrahi (mL) o te otinga EDTA e pau ana i te whakamātautau i ngā tauira āwhina tukatuka ACR.

V # – Te rōrahi o te otinga i pau i te wā whakamātautau pātea

M – Paunatia te papatipu (g) ​​o te tauira āwhina tukatuka ACR.

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 mō te 1 hāora, whakamataohia, ka paunatia hei tatau i te toenga o te wera. Mena ka tāpirihia he matū kore-waro ki ngā tauira āwhina tukatuka ACR, ka nui ake te toenga.
