Momwe mungayesere kuonjezedwa kwa zinthu zopanda organic i

Momwe mungayesere kuwonjezera kwa zinthu za inorganic mu ACR processing aids:

Njira yodziwira Ca2+:

Zida zoyesera ndi ma reagents: beaker; botolo lopangidwa ndi cone; Funnel; burette; Ng'anjo yamagetsi; Mowa wopanda madzi; Hydrochloric acid, NH3-NH4Cl yankho la buffer, chizindikiro cha calcium, 0.02mol/L EDTA njira yothetsera.

Njira zoyesera:

1. Yezerani molondola kuchuluka kwa ACR processing aid chitsanzo (zolondola kwa 0.0001g) ndikuyika mu beaker. Nyowetsani ndi ethanol ya anhydrous, kenaka yikani owonjezera 1: 1 hydrochloric acid ndikutenthetsa pa ng'anjo yamagetsi kuti mutengere ayoni a calcium ndi hydrochloric acid;

2. Sambani ndi madzi ndikusefa kudzera muzitsulo kuti mupeze madzi omveka bwino;

3. Sinthani pH mtengo kukhala wamkulu kuposa 12 ndi NH3-NH4Cl yankho la buffer, onjezani kuchuluka koyenera kwa chizindikiro cha calcium, ndi titrate ndi 0.02mol / L EDTA njira yothetsera. Mapeto ndi pamene mtundu umasintha kuchokera ku chibakuwa wofiira kupita ku buluu weniweni;

4. Chitani zoyeserera zopanda kanthu nthawi imodzi;

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

V - Voliyumu (mL) ya yankho la EDTA lomwe limagwiritsidwa ntchito poyesa zitsanzo zothandizira kukonza za ACR.

V # - Voliyumu ya yankho lomwe limagwiritsidwa ntchito panthawi yoyesera yopanda kanthu

M - Yesani kulemera (g) kwa chitsanzo cha ACR processing aid.

Njira yowotcha yoyezera zinthu za inorganic:

Zida zoyesera: kuwerengera bwino, ng'anjo yamoto.

Njira zoyesera: Tengani zitsanzo zothandizira 0.5,1.0g ACR (zolondola mpaka 0.001g), zikhazikike mu ng'anjo yamoto yotentha ya 950 kwa ola limodzi, kuziziritsa, ndikulemera kuti muwerenge zotsalira zotsalira. Ngati zinthu za inorganic ziwonjezedwa ku zitsanzo zothandizira kukonza za ACR, padzakhala zotsalira zambiri.
