Ib qho yooj yim, tshiab thiab rhiab spectrophotometric txoj kev tau piav qhia rau kev txiav txim siab tib lub sijhawm ntawm mercury thiab palladium.Cov txheej txheem yog ua raws li kev tsim cov mercury thiab palladium nrog Thio-Michler's Ketone (TMK) ntawm pH 3.5.Txhua yam cuam tshuam rau ntawm qhov rhiab heev tau ua kom zoo dua qub thiab cov kab hluav taws xob muaj zog rau kev txiav txim siab ntawm mercury thiab palladium pom.Kev txiav txim siab ib txhij ntawm mercury thiab palladium sib tov los ntawm kev siv txoj kev spectrophotometric yog ib qho teeb meem nyuaj, vim muaj kev cuam tshuam spectral.Los ntawm txoj kev sib txawv ntawm ntau qhov sib txawv xws li ib nrab qhov tsawg kawg nkaus squares (PLS), nws tuaj yeem tau txais cov qauv hloov kho rau qhov ntsuas qhov tseem ceeb ntawm cov khoom sib xyaw uas siv hauv cov calibration ntau.Orthogonal teeb liab kho (OSC) yog cov txheej txheem ua ntej siv los tshem tawm cov ntaub ntawv tsis cuam tshuam nrog lub hom phiaj hloov pauv raws li kev txwv tus thawj tswj hwm kev tsom xam.OSC yog ib txoj hauv kev tsim nyog ua ntej rau PLS calibration ntawm cov khoom sib tov yam tsis tau poob ntawm kev kwv yees muaj peev xwm siv txoj kev spectrophotometric.Nyob rau hauv txoj kev tshawb no, tus qauv calibration yog raws li nyob rau hauv absorption spectra nyob rau hauv lub 360-660 nm ntau yam rau 25 sib txawv mixs ntawm mercury thiab palladium.Calibration matrices muaj 0.025-1.60 thiab 0.05-0.50 microg mL (-1) ntawm mercury thiab palladium, feem.RMSEP rau mercury thiab palladium nrog OSC thiab tsis muaj OSC yog 0.013, 0.006 thiab 0.048, 0.030, feem.Cov txheej txheem no tso cai rau kev txiav txim siab ib txhij ntawm mercury thiab palladium hauv cov qauv hluavtaws thiab cov matrix tiag tiag kev ntseeg tau zoo ntawm kev txiav txim siab.
