Kodi mungayese bwanji kuwonjezera zinthu zopanda chilengedwe mu zothandizira kukonza ACR?

Njira yodziwira Ca2+:

Zipangizo zoyesera ndi zoyezera: ma beakers; Botolo la conical; Funnel; Burette; Furnace yamagetsi; Anhydrous ethanol; Hydrochloric acid, NH3-NH4Cl buffer solution, calcium indicator, 0.02mol/LEDTA standard solution.

Masitepe oyesera:
1. Yesani molondola kuchuluka kwa chitsanzo chothandizira kukonza ACR (cholondola mpaka 0.0001g) ndikuchiyika mu beaker. Chinyowetseni ndi anhydrous ethanol, kenako onjezerani hydrochloric acid yochulukirapo ya 1:1 ndikuyitentha pa uvuni wamagetsi kuti ma calcium ions azitha kuchita bwino ndi hydrochloric acid;
2. Tsukani ndi madzi ndikusefa ndi funnel kuti mupeze madzi ake owoneka bwino;
3. Sinthani pH kuti ikhale yoposa 12 pogwiritsa ntchito yankho la NH3-NH4Cl buffer, onjezerani kuchuluka koyenera kwa calcium indicator, ndikuyika titrate ndi yankho lokhazikika la 0.02mol/LEDTA. Mapeto ake ndi pamene mtundu umasintha kuchoka pa wofiira wofiirira kupita ku buluu weniweni;
4. Chitani mayeso opanda kanthu nthawi imodzi;
5. Werengani C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Kuchuluka kwa yankho la EDTA lomwe limagwiritsidwa ntchito poyesa zitsanzo zothandizira processing ACR (mL).
V # - Kuchuluka kwa yankho lomwe lagwiritsidwa ntchito panthawi yoyesa yopanda kanthu
M — Yesani kulemera kwa chitsanzo cha ACR processing aid (g).

Njira yotenthetsera poyezera zinthu zosapangidwa:
Zida zoyesera: kulinganiza bwino, ng'anjo yoziziritsa.
Masitepe Oyesera: Tengani zitsanzo zothandizira kukonza ACR za 0.5,1.0g (zolondola mpaka 0.001g), ziyikeni mu uvuni wa muffle wotentha wa madigiri 950 ndikuziwotcha kwa ola limodzi, kenako ziziziritseni ndikuyeza kuti muwerengere zinthu zotsala zomwe zapsa. Ngati zinthu zopanda chilengedwe ziwonjezedwa ku chitsanzo cha zothandizira kukonza ACR, padzakhala zotsalira zambiri.
Njira yosungunulira:
1. Zipangizo zoyesera ndi kusanthula bwino kwa reagent; botolo la volumetric la 25mL; Trichloromethane.
Gawo 2: Malinga ndi njira yoyesera ya ACR intrinsic viscosity, yesani 75mg ya chitsanzocho ndikuchiyika mu botolo la volumetric la 25mL. Onjezani solvent ya trichloromethane. Ngati pali matope kapena kuwala kooneka
