Ng’anjo yamagetsi yoyesera phulusa ndondomeko njira kwa mphira mafakitale

Njira yeniyeni yochizira phulusa la rabara yamakampani yopanda halogen ndi motere:

1. Yezerani pafupifupi 0.15 g ya chitsanzo chodulidwa bwino (kulemera mpaka 0.0001g) mu 100mL crucible yadothi, ikani mu ng’anjo yamagetsi yoyesera (550±25) ℃ ndikutenthetsa kwa mphindi pafupifupi 30, itulutseni ndikuyiyikamo. chowotcha kuti chizizire mpaka kutentha kwa chipinda. Chotsani ndi kuyeza.

2. Kenaka ikani chitsanzo choyezera mu crucible mu dzenje la mbale ya asibesitosi, ndipo pang’onopang’ono mutenthe crucible ndi graphite digester mu fume hood yotopa bwino kuti sampuli isagwire moto kapena kuwomba kapena kusefukira. Pambuyo pakuwonongeka kwa mphira ndi carbonized, kutentha kumawonjezeka mpaka zinthu zowonongeka zowonongeka zatha, ndikusiya zotsalira zouma za carbonized.

3. Sunthani crucible yomwe ili ndi zotsalira mu ng’anjo yamagetsi yoyesera pa kutentha kwa (550±25) ℃, ndipo pitirizani kuitentha mpaka itakhala phulusa loyera pansi pa mpweya wabwino.

4. Chotsani phulusa la phulusa kuchokera ku ng’anjo yamagetsi yoyesera, ikani mu desiccator kuti muzizizira kutentha kwa firiji, ndikuyezerani ku 0.1 mg yapafupi.

5. Ikaninso crucible yokhala ndi phulusa mu ng’anjo yamagetsi yoyesera pa (550±25) ℃ kapena (950±25) ℃ kwa mphindi pafupifupi 30, itulutseni ndikuyiyika mu desiccator kuti izizire mpaka kutentha, itengeni. tulukani ndi kuchiyezanso.

6. Bwerezani masitepe omwe ali pamwambawa, kutentha ndi kuzizira, mpaka kusiyana kwa kulemera sikuposa 1mg.
