I-halogenated acetic acid emanzini okuphuza
Amasampuli ahlungwa ngesihlungi somgogodla wesihlabathi.Kusetshenziswa i-CIC-D120 ion chromatograph, SH-AC-3 anion chromatographic column, 2.4mM Na2CO3/3.6mM NaHCO3 eluent kanye nendlela ye-bipolar pulse conductance, ngaphansi kwezimo zechromatographic ezinconyiwe, i-chromatogram imi kanje....Funda kabanzi -
Amanzi amaminerali
Amanzi amaminerali awuhlobo lwamanzi agelezayo ngokuzenzakalelayo ekujuleni komhlaba noma aqoqwe ngokumba futhi aqukethe inani elithile lamaminerali, izakhi zokulandelela noma ezinye izakhi futhi angangcolisiwe endaweni ethile futhi athatha izinyathelo zokuvimbela ukuze...Funda kabanzi -
Ukuhlaziywa kwamanzi okuphuza
Amanzi awumthombo wokuphila.Kufanele senze bonke abantu baneliseke (anele, aphephile futhi kulula ukuwathola) amanzi.Ukwenza ngcono ukutholakala kwamanzi okuphuza aphephile kungaletha izinzuzo ezibonakalayo empilweni yomphakathi, futhi kufanele kwenziwe yonke imizamo yokuqinisekisa ukusetshenziswa okuphephile kwamanzi okuphuza.T...Funda kabanzi -
I-Bromate emanzini amaminerali
I-Bromate iwuhlobo lwento eqinile ye-carcinogenic, okuwumkhiqizo wokwelapha okubulala amagciwane kusetshenziswa i-ozone.Kuyinto yokuhlola okudingekayo ukukhiqizwa kwamanzi amaminerali.Isebenzisa i-CIC-D120 ion chromatograph, SH-AC-11 Ikholomu kanye ne-15.0 mM NaOH eluent, ichromatogram iyi...Funda kabanzi -
Ukuhlaziywa kwamafutha
Ngokusekelwe ekushiseni kwe-petroleum, i-chlorine, i-nitrogen nesibabule emikhiqizweni ye-petroleum iguqulwa ibe ama-hydride nama-oxides ekushiseni okuphezulu ngesithando somlilo, bese imuncwa utshwala be-alkali.Kusetshenziswa i-CIC-D120 ion chromatograph, ikholomu ye-anion ye-SH-AC-3, 3.6 mM N...Funda kabanzi -
Amanzi angcolile asensimini kawoyela
Ukukhetha isilinganiso esifanele sokuhlanjululwa ukuze kuhlanjululwe amanzi angcolile asensimini kawoyela, i-diluent yahlungwa ngolwelwesi oluncane lwe-microporous ongu-0.22 um futhi yaphathwa ngekholomu ye-IC-RP. Uma isampula iqukethe ama-ion ensimbi ensimbi esindayo, kufanele iphathwe ngekholomu ye-IC-Na .Isebenzisa i-CIC-D120 ion...Funda kabanzi -
Ukugawula udaka
Ngesikhathi sokumba, ukujikeleza kabusha kanye nokwengezwa koketshezi lokumba kuzosebenzisana nakanjani noketshezi lwe-stratum futhi kubangele izinguquko eziqhubekayo zamakhemikhali, ezizoshintsha izakhiwo zoketshezi lokumba futhi kuholele ekushintsheni kwezinhlobo ze-ion kanye nokugxila kwe-filtra yokumba uketshezi...Funda kabanzi -
Izinhlayiya zasemkhathini
Amasampula emvelo evolumu ethile noma isikhathi aqoqwa ngokuya ngezidingo zesampula ze-TSP, PM10, uthuli lwemvelo neziphepho zothuli emkhathini.Ingxenye yesine yamasampula olwelwesi lwesihlungi aqoqiwe asikwa kahle abe amabhodlela epulasitiki, anezela u-20mL...Funda kabanzi -
Amanzi angaphezulu
Amanzi angaphezulu ngokuvamile ahlanzekile.Ngemuva kwemizuzu engama-30 yemvula yemvelo, kuthathwa ingxenye engeyona imvula yongqimba olungaphezulu ukuze ihlaziywe.Uma kukhona izinto eziningi ezimisiwe kusampula yamanzi noma umbala umnyama, yiphathe kusengaphambili nge-centrifugation, fi...Funda kabanzi -
Ukuhlaziywa kwemvelo
I-F-, Cl-, NO2-, SO42-, Na+, K+, NH4+, Mg2+, Ca2+, njll. izinto ezidingekayo okufanele zitholwe ocwaningweni lwekhwalithi yomoya kanye nemvula.I-Ion chromatography (IC) iyindlela efaneleke kakhulu yokuhlaziywa kwalezi zinto ze-ionic.Isampula yegesi esemkhathini:Okujwayelekile...Funda kabanzi
