Habka lagu ogaanayo Ca2+:
Qalabka tijaabada iyo reagents: beakers; Qalab koofiyad ah; Funnel; Burette; foornada korontada; ethanol anhydrous; Hydrochloric acid, NH3-NH4Cl xal kaydiyaha, tilmaame kaalshiyam, 0.02mol/LEDTA 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 xad-dhaaf ah 1: 1 hydrochloric acid oo ku kululee foornada korantada si ay ugu oggolaato ions calcium inay si buuxda uga falceliyaan hydrochloric acid;
2. Biyo ku maydh oo ku shaandhee godad si aad u hesho dareere saafi ah;
3. Ku hagaaji qiimaha pH si uu uga weynaado 12 adigoo isticmaalaya NH3-NH4Cl xal, ku dar qadar ku habboon tilmaame kaalshiyam, iyo titrate leh 0.02mol/LEDTA xal caadi ah. Dhamaadka dhamaadka waa marka midabku ka beddelo casaan guduudan oo buluug saafi ah;
4. Samee tijaabo maran isku mar;
5. Xisaabi C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Mugga xalka EDTA ee la isticmaalo marka la tijaabinayo muunadaha gargaarka farsamaynta ee ACR (mL).
V # - Mugga xalka la isticmaalo inta lagu jiro tijaabada maran
M — Miisaam tirada muunadda gargaarka habaynta ACR (g).
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 oo gubo 1 saac, ka dibna qabooji oo miisaan si aad u xisaabiso walxaha gubtay ee hadhay. Haddii walxaha aan noolaha ahayn lagu daro muunada agabka wax qabad ee ACR, waxaa jiri doona hadhaa badan.
Habka xalinta:
1. Qalabka tijaabada iyo dheelitirka falanqaynta reagent; 25 ml oo biyo ah; Trichloromethane.
Talaabada 2: Marka loo eego habka tijaabada viscosity-ga ee ACR, miisaan 75mg muunada oo ku rid weel mug leh oo 25mL ah. Ku dar dareeraha trichloromethane. Haddii uu jiro turbid ama iftiin muuqda
