Otu esi anwale mgbakwunye nke ihe ndị na-adịghị mma na ihe enyemaka nhazi ACR:

Usoro nchọpụta maka Ca2+:

Ngwa nnwale na ihe ndị e ji eme ihe: beaker; karama dị ka kọn; Funnel; burette; Ọkụ eletriki; ethanol anhydrous; Hydrochloric acid, NH3-NH4Cl buffer solution, calcium indicator, 0.02mol/L EDTA solution ọkọlọtọ.

Usoro nnwale:

1. Tụọ nke ọma nha nke ihe nlele ACR (nke ziri ezi ruo 0.0001g) ma tinye ya n'ime beaker. Jiri ethanol anhydrous mee ya mmiri, wee tinye ihe karịrị 1:1 hydrochloric acid ma kpoo ya ọkụ n'elu ọkụ eletrik iji mee ka calcium ions ahụ meghachi omume kpamkpam na hydrochloric acid;

2. Jiri mmiri saa ahụ ma sachaa ya site na funnel iji nweta mmiri doro anya;

3. Gbanwee uru pH ka ọ bụrụ ihe karịrị 12 site na iji ihe nchekwa NH3-NH4Cl, tinye ego kwesịrị ekwesị nke ihe ngosi calcium, wee titrate ya na ngwọta ọkọlọtọ EDTA 0.02mol/L. Isi njedebe bụ mgbe agba ahụ gbanwere site na ọbara ọbara odo odo gaa na acha anụnụ anụnụ dị ọcha;

4. Mee nnwale efu n'otu oge;

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

V - Olu (mL) nke ihe ngwọta EDTA e riri mgbe a na-anwale ihe nlele enyemaka nhazi ACR.

V # - Olu nke ihe ngwọta e ji mee ihe n'oge nnwale efu

M - Tụọ oke (g) nke ihe nlele enyemaka nhazi ACR.

Usoro ọkụ maka ịtụ ihe ndị na-adịghị n'ime ahụ:

Ngwa nnwale: nguzozi nyocha, ọkụ muffle.

Usoro nnwale: Were ihe nlele enyemaka nhazi ACR 0.5,1.0g (nke ziri ezi ruo 0.001g), tinye ha n'ime ọkụ muffle okpomọkụ 950 na-agbanwe agbanwe ruo otu awa, jụọ oyi, ma tụọ ya iji gbakọọ ihe fọdụrụ n'ọkụ. Ọ bụrụ na etinyere ihe ndị na-adịghị ndụ na ihe nlele enyemaka nhazi ACR, a ga-enwe ihe fọdụrụ karịa.
