Maitiro ekuyedza kuwedzerwa kwezvinhu zvisina organic i

Maitiro ekuyedza kuwedzerwa kwezvinhu zvisina organic muACR processing aids:

Nzira yekuona Ca2+:

Zvishandiso zvekuedza uye ma reagents: beaker; Bhodhoro rakaita sekone; Funnel; burette; Furnace yemagetsi; Anhydrous ethanol; Hydrochloric acid, NH3-NH4Cl buffer solution, calcium indicator, 0.02mol/L EDTA standard solution.

Matanho ekuyedza:

1. Yera nemazvo huwandu hwakati hweACR processing aid sampuro (yakarurama kusvika 0.0001g) woiisa mubeaker. Nyorovesa neanhydrous ethanol, wobva wawedzera 1:1 hydrochloric acid woipisa pamoto wemagetsi kuti iite calcium ions nehydrochloric acid zvakakwana;

2. Geza nemvura wosefa nepaburi kuti mvura yacho ibude yakachena;

3. Gadzirisa pH kuti ipfuure 12 uchishandisa NH3-NH4Cl buffer solution, wedzera huwandu hwakakodzera hwecalcium indicator, wobva wawedzera titrate ne 0.02mol/L EDTA standard solution. Mugumo ndewekuti kana ruvara rwukachinja kubva patsvuku yepepuru kuenda pabhuruu chaiyo;

4. Itai kuedza kusina chinhu panguva imwe chete;

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

V - Huwandu (mL) hwemhinduro yeEDTA inonwiwa pakuyedzwa kwesampuli dzekubatsira pakugadzirisa ACR.

V # - Huwandu hwemushonga wakashandiswa panguva yekuedza kusina chinhu

M - Yera huremu (g) ​​hwemuenzaniso wekubatsira kugadzirira ACR.

Nzira yekupisa yekuyera zvinhu zvisina organic:

Zvishandiso zvekuedza: chiyero chekuongorora, muffle furnace.

Matanho ekuyedza: Tora 0.5,1.0g yeACR processing aid sampuro (dzakarurama kusvika 0.001g), dziise mufurnace yemuffle inodziya 950 kweawa imwe chete, dzitonhore, wozoyera kuti uone zvasara zvekutsva. Kana zvinhu zvisina organic zvikawedzerwa kune sampuli dzeACR processing aid, pachava nezvakawanda zvasara.
