302-95-4 - mayeso
Sodium
Tengani mlingo woyenerera wa sodium standard solution ndikuwasungunula mochulukira ndi madzi kuti 1 ml iliyonse ili ndi 0.16jLtg ndi 0. 4 Net, 0. 8 ^ tg.1.0 / ig, 1. 2pg yankho, monga njira yothetsera;Tengani mankhwala 0.14g, mwatsatanetsatane masekeli, platinamu crucible, pang'onopang'ono mkangano kumaliza carbonization, ozizira, kuwonjezera asidi sulfuric 0 .5M l kunyowa, kutentha otsika Kutentha kwa sulfuric acid nthunzi kuchotsa pambuyo poyaka pa 600 ℃ kwa nkhani yoyera imvi, ozizira. , mwatsatanetsatane Mphamvu 1 mu hydrochloric acid lm l kusungunuka ndi quantitatively anasamutsidwa 100ml kuyeza botolo, kuchepetsedwa ndi madzi sikelo, kugwedeza, mwatsatanetsatane kutenga lm l 100ml kuyeza botolo, kuchepetsedwa ndi madzi sikelo, monga njira yothetsera mayeso.Yankho lopanda kanthu linakonzedwa ndi njira yomweyo, ndipo linayesedwa ndi kuwerengeredwa pa kutalika kwa 589.0 nm ndi atomic mayamwidwe spectrophotometry (General Rule 0406 njira yoyamba).Kutengera ndi mankhwala owuma, sodium yokhutira iyenera kukhala 5.0% ~ 6.1%.
Kumveka bwino ndi mtundu wa yankho
Tengani 0.5g ya mankhwalawa, Onjezani 10ml ya madzi kuti musungunuke, fufuzani motsatira lamulo (General Rule 0901 ndi General Rule 0902 ), yankho liyenera kukhala lomveka komanso lopanda mtundu.Pankhani ya chitukuko cha mtundu, sichidzakhala chozama kuposa chikasu cha 1 Standard Colorimetric solution (General rule 0901).
Kutaya pakuyanika
Tengani mankhwalawa, pa 60 ℃ pansi pa kuyanika kwapang'onopang'ono mpaka kulemera kosalekeza, kuwonda sayenera kupitirira 5.0% (General ulamuliro 0831).
Zitsulo zolemera
tengani 1.0 g ya mankhwalawa, muyike mu platinamu crucible, ndikuyang'ana motsatira malamulo (General lamulo 0821 lamulo lachiwiri).Zolemera zazitsulo sizidzapitirira magawo 20 pa milioni.
Arsenic mchere
Tengani mankhwalawa 1.0 g, onjezerani 500% magnesium nitrate ethanol solution, kuyatsa Mowa, kutentha pang'ono mpaka phulusa, ngati pali carbonized, mukhoza kuwonjezera pang'ono nitric acid yonyowa, pitirizani kutentha (~ 60 (TC)) pambuyo phulusa wathunthu, kuziziritsa pansi, kuwonjezera madzi 21ml kupasuka, kuwonjezera asidi hydrochloric 5ml, fufuzani malinga ndi lamulo (General ulamuliro 0822 lamulo loyamba), ayenera kutsatira malamulo (0.0002%).
302-95-4 - Kutsimikiza kokhutira
Tengani mankhwalawa pafupifupi 0.3g, kulemera kwake, kuwonjezera anhydrous formic acid 5 ml kuti asungunuke, onjezani glacial acetic acid 35 ml, potentiometric titration (General Rule 0701), ndi perchloric acid titration solution (0.1 mol/L) titration, ndi zotsatira zake a titration adakonzedwa ndi mayeso opanda kanthu.L iliyonse ya perchloric acid titration solution (0.1 mol/l) imafanana ndi 41.46mg ya C24H39NaO4.
