I-acetoneNgaba lulwelo olungenabala, lubonakale lulwelo nge-odor ebukhali necaphukisayo. Sisinyibilikisi esinokutsha kunye ne-orlating esiguquguqukayo kwaye sisetyenziswa ngokubanzi kumzi mveliso, amayeza, kunye nobomi bemihla ngemihla. Kweli nqaku, siza kuphonononga iindlela zokuchonga i-acetone.

umzi-mveliso we-acetone

 

1. Ukuchongwa kokubonakalayo

 

Ukuchongwa kokubonakalayo yenye yeendlela ezilula zokuchonga i-acetone. I-Acetone ecocekileyo yi-allue engenabala kwaye ingenamandla, ngaphandle kokungcola okanye i-sediment. Ukuba ufumanisa ukuba isisombululo sityheli okanye i-turbid, ibonisa ukuba kukho ukungcola okanye i-sediment kwisisombululo.

 

2. I-infrared spectrum yesazisi

 

Ukuchongwa kwe-infrared spectrum yindlela eqhelekileyo yokuchonga izinto zezinto eziphilayo. Imigca ye-organs ye-organic ye-infrared eyahlukileyo ye-infrared i-spectra, enokusetyenziswa njengesiseko sokuchonga. I-Acetone ecocekileyo ine-inqwayithi ye-acketone inesimo se-1735 cm-1 kwi-infradrum spectrum, eyi-carbonyl yolula i-chibiction ye-chibiction yeqela leKetone. Ukuba ezinye izinto zivela kwisampulu, kuya kubakho iinguqu kwindawo yokuthambisa ye-afception okanye imbonakalo ye-peces entsha yokufunxa. Ke ngoko, isazisi sobuchwephesha obungasetyenziselwa ukubonisa i-acetone kwaye bahlule kwezinye iiviwuni.

 

I-3. I-chromatography yegesi

 

I-chromatography yegesi yindlela yokwahlula kunye nokuhlalutya imichiza eguqukayo. Ingasetyenziselwa ukwahlula kwaye ihlalutye amacandelo omxube ontsonkothileyo kwaye afumane umxholo wecandelo ngalinye. I-acetone ecocekileyo ine-chromatographic ethile kwi-chromatom yegesi, ixesha lokugcina malunga ne-1.8 imizuzu. Ukuba ezinye iikhomputha ziyavela kwisampulu, kuya kubakho utshintsho kwixesha lokugcina i-acetone okanye imbonakalo ye-chiromatographic entsha. Ke ngoko, i-chromatography yegesi inokusetyenziselwa ukubonisa i-acetone kwaye ukwahlula kwezinye izinto ezihlanganisiweyo.

 

I-4. Ubunzima bokuchonga i-Spectrometry

 

I-Mass Spectrometry yindlela yokuchonga imilinganiselo ye-organic e-Ionis kwi-vacuum ye-vacuum engaphantsi kwe-Informina ye-Elesm ePhakamileyo ye-Ionfornes ngu-Ioled Proubragraph. I-orgaund nganye inophawu olunobunzima obukhethekileyo, olunokusetyenziswa njengesiseko sokuchonga. I-acetone ecocekileyo ine-suctur spectrum ye-peak kwi-m / z = 43, eyi-molecular ion incoak ye-acetone. Ukuba ezinye izinto ezikhoyo zivela kwisampulu, kuya kubakho utshintsho kwi-Mass Spectrum Spectrum Peak okanye imbonakalo ye-Susctum entsha. Ke ngoko, i-spectrometry inokusetyenziswa ukubonisa i-acetone kwaye ukwahlula kwezinye izihlangani.

 

Kwisishwankathelo, isazisi esibonakalayo, isazisi se-infrared spection, i-chromatography yegesi, kunye nokuchongwa kobuninzi bokuchonga kunokusetyenziswa ukubonisa i-acetone. Nangona kunjalo, ezi ndlela zifuna izixhobo zobungcali kunye nokusebenza kwezobugcisa, ke kuyacetyiswa ukuba usebenzise amaziko ovavanyo lobuchule ukuze uchonge.
