Discuss the difference and affection of mobile phase (water/ 1mM NH4NO3/ 10mM NH4NO3/ 10mM NaNO3/ 10mM NH4Cl), separation channel membrane (RC/PES) and filter 0.45µm/1µm filtration. The fractionated sample would be analyzed through Pyrolysis-GCMS and ICP-MS to acquire the composition information on organic compound and heavy metal.
From the results, the higher ionic strength mobile phase, the lower light scattering intensity because particles adsorb on the channel membrane and lower the releasing. The higher ionic strength mobile phase could also delay particles releasing. Separation channel PES membrane delay the lighting scattering peaks and particles distribution compared with RC membrane. Compared with 1µm filter, 0.45µm filter condition show great separation, stable size variation and small average size. The main UV adsorption area is 13~15 mins.
We collect three particles size fraction <10nm, 10~100nm and 100~450nm under RC membrane/ 0.45µm filter/ water mobile phase condition. The heavy metal analysis from ICP-MS show Danshuei Wetland, Gaoping River, Houjin River and Kinmen focus on 10~100nm；Zengwun Estuary Wetland, Beigang River and Erren River focus on 100~450nm. The organic compounds distribution from EGA spectrum show three temperature ranges:100~150℃, 170~400℃ and 500~650℃. The temperature range 100~400℃ means humic substrate, and 500~650℃ range means carbon element or CaCO3 compound." ， 欄位Project Year的內容是2016 ， 欄位Organizer的內容是"Environmental Analysis Laboratory" ， 欄位Executive Unit的內容是"知本生技有限公司" ， 欄位Reporting download URL的內容是https://epq.epa.gov.tw/project/filedownload.aspx?fid=131346 ， 欄位Publish Date的內容是20180201 。
