Nheyo dzeX-Ray Fluorescence (XRF) Kuongorora
Kuongororwa kweX-ray fluorescence (XRF) kunofadza maatomu ari mumuenzaniso nekuaisa paX-rays ine simba guru. MaX-ray ekutanga anoburitsa maerekitironi emukati megoko, zvichiita kuti pave nenzvimbo dzisina vanhu. Maerekitironi anobva kumagoko akakwirira anozadza nzvimbo idzi, achiburitsa maX-rays echipiri. Chinhu chimwe nechimwe chinoburitsa chigunwe chakasiyana cheX-rays yechipiri, zvichibvumira kuzivikanwa zvakananga uye kuverengwa kwenhamba.
Kuongororwa kwezvinhu zveXRF kunosanganisira zvinhu kubva kuMg (12) kusvika kuuranium (U, 92). Kuongororwa kweXRF kwemazuva ano kunoona kuwanda kwezvikamu pamamiriyoni. Zvishandiso zvekuongorora zvinhu zvemhando yepamusoro murabhoritari yekuongorora zvinhu zveXRF zvinopa mhedzisiro yemhando yepamusoro uye yehuwandu pasinei nekuoma kwe matrix.
Kuongororwa kweXRF kusingaparadze kunochengetedza sampuli. Kuongororwa kwakawanda hakudi kugadzirira sampuli zvakanyanya kana kusada. Zvishandiso zveXRF analyzer zvinotakurika zvinotsigira kuongororwa nekukurumidza, panzvimbo. Masevhisi eXRF spectroscopy uye nzvimbo dzekuongorora makemikari eXRF dzinovimba nemisimboti iyi kuti pave nemhedzisiro yepamusoro uye yekutevera.
Matambudziko eindasitiri akagadziriswa neXRF
Kuongororwa kwezvinhu zve XRF kunogonesa kuzivikanwa kwakarurama uye kuverengwa kwesimbi dzakasanganiswa, zvicherwa, zvinwiwa, uye hupfu mumasekonzi mashoma. Kuongororwa kwe XRF hakuparadzi uye kunotsigira zvakananga kuongororwa kwe XRF nekukurumidza panguva yekutarisa maitiro esimbi, kuchera, uye kudzokorodza.
In kugadzira simbi, XRF inoona zvinhu zvechisikigo uye inotsvaga huwandu hwezvinhu zvakasvibiswa musimbi dzisina ngura uye ma alloys akakosha. Matekinoroji aripo e micro-XRF anogadzirisa kugoverwa kwe3D elemental pa micrometer scales, zvakakosha pakugadzirwa kwezvinhu zvepamusoro.
Kune vanochera, vanoongorora XRF vanobata nemaoko uye vanotakurika vanopa ongororo yemhando yeXRF, vachigadzira simbi dzakakosha dzakadai seNi, Cu, uye zvinhu zvisingawanzoonekwi muore. Mukugadzirisazve, masisitimu eXRF ari mumutsara uye nzvimbo dzekuongorora XRF dzinotungamira kurongeka, kuderedza kukanganisa uye kuona kuchena.
Kuongororwa kwevhu reXRF kunoratidza simbi dzinorema dzakadai sePb, As, uye Cd pamazinga eppm, zvichitsigira kutariswa kwezvakatipoteredza uye kutevedzera mitemo.
