Sodium
Nka tekanyo e loketseng ea sodium standard solution 'me u e hlapolle ka bongata ka metsi ho etsa 1 ml ka 'ngoe e nang le 0.16jLtg le 0. 4 Net, 0. 8 ^ tg.1.0/ig, 1. 2pg tharollo, e le tharollo ea litšupiso;Nka sehlahisoa sena 0.14g, boima ba 'mele bo nepahetseng, platinum crucible, butle-butle e halefile ho tlatsa carbonization, e pholile, eketsa sulfuric acid 0 .5M l ho metsi, mocheso o tlaase oa mocheso ho tloha ho sulfuric acid ho tlosoa mouoane ka mor'a ho chesa ka 600 ℃ ho ntho e tšoeu e bohlooho, e pholileng. , Precision Force 1 into hydrochloric acid lm l qhibiliha le quantitatively fetisetsoa ho 100ml lekanya botlolo, diluted ka metsi ho ea sekala, sisinya, ho nepahala nka lm l 100ml lekanya botlolo, diluted ka metsi ho ea sekaleng, e le teko tharollo.Tharollo e se nang letho e ile ea lokisoa ka mokhoa o ts'oanang, 'me e lekantsoe le ho baloa ka bolelele ba 589.0 nm ka atomic absorption spectrophotometry (Molao oa Kakaretso oa 0406 mokhoa oa pele).Ho ipapisitsoe le sehlahisoa se omeletseng, litaba tsa sodium e lokela ho ba 5.0% ~ 6.1%.
Ho hlaka le 'mala oa tharollo
Nka 0.5g ea sehlahisoa sena, Eketsa 10ml ea metsi ho qhibiliha, hlahloba ho ea ka molao (Molao o akaretsang oa 0901 le Molao oa Kakaretso oa 0902 ), tharollo e lokela ho ba e hlakileng le e se nang mebala.Tabeng ea nts'etsopele ea 'mala, e ke ke ea teba ho feta tebello e mosehla No. 1 Standard Colorimetric solution (Molao o akaretsang oa 0901).
Tahlehelo ka ho omisa
Nka sehlahisoa sena, ho 60 ℃ tlas'a khatello e fokotsehileng ea ho omisa ho boima bo sa khaotseng, ho lahleheloa ke boima ba 'mele ha hoa lokela ho feta 5.0% (Molao o akaretsang 0831).
Litšepe tse boima
nka 1.0 g ea sehlahisoa sena, e behe ka har'a crucible ea platinum, 'me ue hlahlobe ho ea ka molao (Molao o akaretsang 0821 molao oa bobeli).Lintho tsa tšepe tse boima ha lia lokela ho feta likarolo tse 20 ho milione.
Letsoai la Arsenic
Nka sehlahisoa sena 1.0 g, eketsa 500% magnesium nitrate ethanol tharollo, khantša ethanol, butle-butle mocheso ho molora, haeba ho ntse ho e-na le carbonized, o ka eketsa palo e nyenyane ea nitric acid e metsi, tsoela pele ho chesa (~ 60 (TC)) ka mor'a molora o feletseng, pholile fatše, eketsa metsi 21ml ho qhibiliha, eketsa hydrochloric acid 5ml, hlahloba ho ea ka molao (Kakaretso ea molao 0822 molao oa pele), e lokela ho lumellana le melao ea tsamaiso (0.0002%).
302-95-4 - Boikemisetso ba litaba
Nka sehlahisoa sena se ka bang 0.3g, boima bo nepahetseng, eketsa anhydrous formic acid 5 ml ho qhibiliha, eketsa glacial acetic acid 35 ml, potentiometric titration (General Rule 0701), ka perchloric acid titration solution (0.1 mol / L) titration, le liphello tsa titration li ile tsa lokisoa ka teko e se nang letho.E 'ngoe le e' ngoe ea l ea perchloric acid titration solution (0.1 mol / l) e lumellana le 41.46mg ea C24H39NaO4.
