Otu esi anwale mgbakwunye nke inorganic bekee i

Otu esi anwale mgbakwunye nke ihe inorganic na enyemaka nhazi ACR:

Usoro nchọpụta maka Ca2+:

Ngwa nnwale na reagents: beaker; Kalama ụdị cone; Ọkụ; agba aja aja; Igwe ọkụ eletrik; ethanol na-egbu egbu; Hydrochloric acid, NH3-NH4Cl ngwọta ngwọta, calcium egosi, 0.02mol/L EDTA ọkọlọtọ ngwọta.

Nnwale nzọụkwụ:

1. Jiri nlezianya tụọ ụfọdụ ihe enyemaka nhazi ACR (nke ruru 0.0001g) ma tinye ya na beaker. Weta ya na ethanol anhydrous, wee tinye 1: 1 hydrochloric acid ngafe ma kpoo ya na ọkụ eletrik iji meghachi omume ion calcium kpamkpam na hydrochloric acid;

2. Jiri mmiri na-asacha ma kpochaa site na oghere iji nweta mmiri mmiri doro anya;

3. Gbanwee uru pH ka ọ dị ukwuu karịa 12 na NH3-NH4Cl ngwọta ngwọta, gbakwunye ego kwesịrị ekwesị nke ihe ngosi calcium, na titrate na ngwọta ọkọlọtọ 0.02mol/L EDTA. Ebe njedebe bụ mgbe agba na-agbanwe site na-acha odo odo na-acha anụnụ anụnụ na-acha anụnụ anụnụ;

4. Mee nnwale efu n'otu oge;

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

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

V # - Olu nke ngwọta riri n'oge nnwale efu

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

Usoro ọkụ maka ịlele ihe inorganic:

Ngwa nnwale: itule nyocha, ọkụ muffle.

Nnwale ule: Were 0.5,1.0g ACR ihe enyemaka nhazi (nke ziri ezi na 0.001g), tinye ha n'ime ọkụ muffle okpomọkụ 950 na-adịgide adịgide maka 1 hour, dị jụụ, ma tụọ iji gbakọọ ihe fọdụrụ ọkụ. Ọ bụrụ na agbakwunyere ihe ndị na-adịghị ahụkebe na ihe enyemaka nhazi ACR, a ga-enwekwu ihe fọdụrụnụ.
