Njira yodziwira Ca2+:
Zida zoyesera ndi ma reagents: beakers; botolo la conical; Funnel; Burette; Ng'anjo yamagetsi; Mowa wopanda madzi; Hydrochloric acid, NH3-NH4Cl yankho la buffer, chizindikiro cha calcium, 0.02mol/LEDTA 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 yonjezerani 1: 1 hydrochloric acid ndikuwotchera pa ng'anjo yamagetsi kuti ma ions a calcium agwirizane ndi hydrochloric acid;
2. Sambani ndi madzi ndikusefa ndi fanjelo kuti mupeze madzi ake omveka bwino;
3. Sinthani pH mtengo kukhala wamkulu kuposa 12 pogwiritsa ntchito NH3-NH4Cl yankho la buffer, yonjezerani chiwerengero choyenera cha calcium, ndi titrate ndi 0.02mol / LEDTA njira yothetsera. Mapeto ndi pamene mtundu umasintha kuchokera ku chibakuwa wofiira kupita ku buluu weniweni;
4. Yesani mayeso opanda kanthu nthawi imodzi;
5. Werengetsani C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Volume ya yankho la EDTA lomwe limagwiritsidwa ntchito poyesa zitsanzo za ACR processing aid (mL).
V # - Voliyumu ya yankho lomwe limagwiritsidwa ntchito pakuyesa kopanda kanthu
M - Wezani unyinji wa ACR processing thandizo chitsanzo (g).
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), ikani mung'anjo yamoto yotentha ya 950 ndikuwotcha kwa ola limodzi, kenako kuziziritsa ndikulemera kuwerengera zotsalazo. Ngati zinthu za inorganic ziwonjezedwa ku zitsanzo za ACR zothandizira kukonza, padzakhala zotsalira zambiri.
Njira yosungunulira:
1. Zida zoyesera ndi kusanthula kwa reagent; botolo la volumetric 25 ml; Trichloromethane.
Khwerero 2: Malinga ndi njira yoyesera ya ACR intrinsic viscosity, yezani 75mg ya chitsanzo ndikuyiyika mu botolo la volumetric 25mL. Onjezerani trichloromethane solvent. Ngati pali turbidity kapena kuwala kowoneka
