Nzira yekuyedza sei kuwedzera kwezvinhu inorganic mu ACR kugadzirisa aids?

Nzira yekuona yeCa2+:

Kuedza zviridzwa uye reagents: mabheki;Conical flask;Funnel;Burette;Choto chemagetsi;Anhydrous ethanol;Hydrochloric acid, NH3-NH4Cl buffer solution, calcium indicator, 0.02mol/LEDTA standard solution.

Matanho ekuedza:
1. Kunyatsoyera imwe chiyero che ACR processing aid sampuli (yakarurama kusvika 0.0001g) uye isa mubeaker.Nyoresa neanhydrous ethanol, wobva wawedzera kuwanda kwe1: 1 hydrochloric acid uye kupisa pachoto chemagetsi kuti ubvumire calcium ions kuti iite zvizere nehydrochloric acid;
2. Geza nemvura uye sefa nefunnel kuti uwane mvura yayo yakajeka;
3. Gadzirisa pH kukosha kuti ive yakakura kudarika 12 uchishandisa NH3-NH4Cl buffer solution, wedzera huwandu hwakakodzera hwe calcium indicator, uye titrate ne 0.02mol / LEDTA standard solution.Mhedziso ndeye apo ruvara runoshanduka kubva kune yepepuru yakatsvuka kusvika kune yakachena yebhuruu;
4. Ita bvunzo isina chinhu panguva imwe chete;
5. Verenga C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Vhoriyamu yeEDTA mhinduro inopedzwa paunenge uchiyedza ACR kugadzirisa aid samples (mL).
V # - Vhoriyamu yemhinduro inopedzwa panguva isina bvunzo
M - Weresa huwandu hwe ACR kugadzirisa rubatsiro sampuli (g).

Kupisa nzira yekuyera inorganic zvinhu:
Kuedza zviridzwa: analytical balance, muffle furnace.
Matanho ekuedza: Tora 0.5,1.0g ACR kugadzirisa aid samples (yakarurama kusvika 0.001g), isa mu 950 inogara tembiricha muffle furenace uye pisa kweawa imwe, wozotonhorera nekuyera kuverenga zvakasara zvakatsva.Kana inorganic zvinhu zvawedzerwa kune sampuli yeACR kugadzirisa aids, pachave nekusara kwakawanda.
Solvent nzira:
1. Zvishandiso zvekuedza uye reagent yekuongorora chiyero;25mL volumetric flask;Trichloromethane.
Danho rechipiri: Zvinoenderana neiyo ACR intrinsic viscosity yekuyedza nzira, huremu 75mg yemuenzaniso woiisa mu25mL volumetric flask.Wedzera trichloromethane solvent.Kana pane turbidity kana chiedza chinooneka
