I-acetic acid eneHalogenated emanzini okusela
Iisampulu zihluzwa ngesihluzo esingundoqo sesanti.Ukusebenzisa iCIC-D120 ion chromatograph, SH-AC-3 anion chromatographic column, 2.4mM Na2CO3/3.6mM NaHCO3 eluent kunye nebipolar pulse conductance method, phantsi kweemeko ezicetyiswayo zechromatographic, ichromatogram imi ngolu hlobo lulandelayo....Funda ngokugqithisileyo -
Amanzi esembiwa
Amanzi eeminerali luhlobo lwamanzi aphuma ngokuzenzekelayo kumbindi ophantsi komhlaba okanye aqokelelwe ngokugrunjwa kwaye aqulethe umlinganiselo othile weeminerali, ukulandelela izinto okanye amanye amacandelo kwaye akangcoliswanga kwindawo ethile kwaye athatha amanyathelo okuthintela ukuze...Funda ngokugqithisileyo -
Uhlalutyo lwamanzi okusela
Amanzi ngumthombo wobomi.Kufuneka senze bonke abantu baneliseke (abanele, akhuselekile kwaye kulula ukuwafumana) ubonelelo lwamanzi.Ukuphucula ukufikelela kumanzi okusela akhuselekileyo kunokuzisa iingenelo ezibonakalayo kwimpilo yoluntu, kwaye kufuneka kwenziwe zonke iinzame zokuqinisekisa ukusetyenziswa okukhuselekileyo kwamanzi okusela.T...Funda ngokugqithisileyo -
I-Bromate emanzini amaminerali
I-Bromate luhlobo lwento eyomeleleyo ye-carcinogenic, eyimveliso yonyango lokubulala iintsholongwane usebenzisa i-ozone.Yinto yokuhlola eyimfuneko kwimveliso yamanzi emineral.Isebenzisa iCIC-D120 ion chromatograph, iKholamu ye-SH-AC-11 kunye ne-15.0 mM NaOH eluent, ikhromatogram yi...Funda ngokugqithisileyo -
Uhlalutyo lweoli
Ngokusekelwe ekutshakeni kwepetroleum, iklorini, initrogen kunye nesulfure kwiimveliso zepetroleum ziguqulwa zibe ziihydrides kunye neeoksidi kubushushu obuphezulu ngesithando somlilo, emva koko ifunxwe butywala bealkali.Isebenzisa iCIC-D120 ion chromatograph, ikholamu yeanion yeSH-AC-3, 3.6 mM N...Funda ngokugqithisileyo -
Amanzi amdaka entsimi yeoli
Ukukhetha i-dilution ratio efanelekileyo yokunciphisa amanzi amdaka entsimi yeoli, i-diluent yahluzwa yi-0.22 um microporous membrane kwaye iphathwa yi-IC-RP column.Ukusebenzisa i-CIC-D120 ion...Funda ngokugqithisileyo -
Ukugawulwa ngodaka
Ngexesha lokugaya, ukujikeleza kwakhona kunye nokongeza ulwelo lokugaya kuya kusebenzisana ngokuqinisekileyo kunye nolwelo lwe-stratum kwaye kubangele utshintsho lweekhemikhali eziqhubekayo, eziya kutshintsha iipropathi ze-drilling fluid kwaye zikhokelele kutshintsho kwiintlobo ze-ion kunye nokuxinwa kwe-drilling fluid filtra...Funda ngokugqithisileyo -
Iincinci ze-atmospheric
Iisampulu zokusingqongileyo zomthamo othile okanye ixesha ziqokelelwa ngokweemfuno zesampulu ze-TSP, PM10, uthuli lwendalo kunye nezivunguvungu zothuli emoyeni.Ikota yeesampulu zokucoca inwebu eziqokelelweyo zisikwe ngokuchanekileyo kwiibhotile zeplastiki, zongeza i-20mL...Funda ngokugqithisileyo -
Amanzi angaphezulu
Amanzi angaphezulu acocekile.Emva kwemizuzu engama-30 yemvula yendalo, ithatha indawo engeyiyo imvula yomaleko ongaphezulu ukuze ihlalutywe.Ukuba kukho izinto ezininzi ezinqunyanyisiweyo kwisampulu yamanzi okanye umbala umnyama, yilungise kwangaphambili nge-centrifugation, fi...Funda ngokugqithisileyo -
Uhlalutyo lokusingqongileyo
I-F-, Cl-, NO2-, SO42-, Na+, K+, NH4+, Mg2+, Ca2+, njl. zizinto eziyimfuneko eziza kufunyanwa kwisifundo somgangatho we-atmospheric kunye nemvula.Ion chromatography (IC) yeyona ndlela ifanelekileyo yohlalutyo lwezi zinto ze-ionic.Isampulu yerhasi ye-atmospheric: Genener...Funda ngokugqithisileyo
