Iisampulu zokusingqongileyo zomthamo othile okanye ixesha ziqokelelwa ngokweemfuno zesampulu ze-TSP, PM10, uthuli lwendalo kunye nezivunguvungu zothuli emoyeni.Ikota yeesampuli ze-membrane zokucoca eziqokelelweyo zinqunywe ngokuchanekileyo kwiibhotile zeplastiki, zongeza i-20mL amanzi ahlanjululweyo, emva koko ivolumu ukuya kwi-50mL emva kokuba ikhutshwe kwi-ultrasonic cleaner kwaye ihluzwe nge-0.45μm i-microporous filter membrane.Emva kwayo yonke le nto, isampuli inokutofwa ukuhlalutya.Ukusebenzisa iCIC-D120 ion chromatograph, SH-AC-3 anion column, 3.6 mM Na2CO3+4.5 mM NaHCO3 eluent kunye nebipolar pulse conductance method,phantsi kweemeko ezicetyiswayo zechromatographic, ichromatogram imi ngolu hlobo lulandelayo.
Isebenzisa iCIC-D120 ion chromatograph, SH-CC-3 ikholamu yecation, 5.5 mM MSA eluent kunye nebipolar pulse conductance method, phantsi kweemeko ezicetyiswayo zechromatographic, ichromatogram imi ngolu hlobo lulandelayo.
