Sida loo tijaabiyo ku darida walxaha aan orgaaniga ahayn ee ACR kaaliyayaasha

Habka lagu ogaanayo Ca2+:

Qalabka tijaabada iyo reagents: beaker; dhalada qaabaysan kolayga; Funnel; burette; foornada korontada; ethanol anhydrous; Hydrochloric acid, NH3-NH4Cl xal kaydiyaha, tilmaame kaalshiyam, 0.02mol/L EDTA xal heerka.

Tijaabooyinka tijaabada:

1. Si sax ah u miisaamo qadar go'an oo ah muunada gargaarka farsamaynta ee ACR (sax ah ilaa 0.0001g) oo ku rid digsi. Ku qoyso ethanol anhydrous ah, ka dibna ku dar 1: 1 hydrochloric acid oo dheeraad ah oo ku kululee foornada korantada si ay si buuxda uga jawaabto ions calcium leh hydrochloric acid;

2. Biyo ku maydh oo ku shaandhee meel god ah si aad u hesho dareeraha saafiga ah;

3. Ku hagaaji qiimaha pH si uu uga weynaado 12 oo leh xal NH3-NH4Cl, ku dar qadar ku habboon tilmaame kaalshiyam, iyo titrate oo leh 0.02mol/L EDTA xalka caadiga ah. Dhamaadka dhamaadka waa marka midabku ka beddelo casaan guduudan oo buluug saafi ah;

4. Samee tijaabooyin madhan isku mar;

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

V - Mugga (mL) ee xalka EDTA ee la isticmaalo marka la tijaabinayo muunado ka shaqaynta ACR

V # - Mugga xalka la isticmaalo inta lagu jiro tijaabada maran

M - Miisaan cufka (g) ee muunadda gargaarka farsamaynta ee ACR.

Habka gubashada ee cabbiraadda walxaha aan organic:

Aaladaha tijaabada: dheelitirka gorfaynta, foornada muffle.

Tijaabooyinka Tijaabada: Qaado 0.5,1.0g ACR muunado gargaar farsamayn ah (sax ah ilaa 0.001g), ku rid foorno heerkul joogto ah 950 ilaa 1 saac, qabooji, oo miisaan si aad u xisaabiso hadhaaga gubashada. Haddii walxaha aan noolaha ahayn lagu daro shaybaarada gargaarka farsamaynta ee ACR, waxaa jiri doona hadhaa badan.
