Njira yosavuta, yatsopano komanso yovuta kwambiri ya spectrophotometric idafotokozedwa kuti iwonetsetse munthawi yomweyo mercury ndi palladium.Njirayi imachokera ku mapangidwe ovuta a mercury ndi palladium ndi Thio-Michler's Ketone (TMK) pa pH 3.5.Zinthu zonse zomwe zimakhudzidwa ndi kukhudzika zidakonzedwa bwino ndipo mizere yosinthika yamtundu wa mercury ndi palladium idapezeka.Kutsimikiza panthawi imodzi ya zosakaniza za mercury ndi palladium pogwiritsa ntchito njira ya spectrophotometric ndizovuta, chifukwa cha kusokoneza kwa spectral.Pogwiritsa ntchito njira zowonetsera ma multivariate monga makwerero ocheperako (PLS), ndizotheka kupeza chitsanzo chomwe chimasinthidwa kumagulu osakanikirana a zosakaniza zomwe zimagwiritsidwa ntchito pamtundu wa calibration.Orthogonal signal correction (OSC) ndi njira yopangiratu yomwe imagwiritsidwa ntchito pochotsa zidziwitso zosakhudzana ndi zomwe mukufuna kutengera kusanthula kwazinthu zazikulu.OSC ndi njira yoyenera yopangira zosakaniza za PLS popanda kutaya mphamvu yolosera pogwiritsa ntchito njira ya spectrophotometric.Mu phunziro ili, chitsanzo cha calibration chimachokera pa mayamwidwe amtundu wa 360-660 nm pamitundu 25 yosakanikirana ya mercury ndi palladium.Masamu owerengera anali ndi 0.025-1.60 ndi 0.05-0.50 microg mL (-1) ya mercury ndi palladium, motsatana.The RMSEP ya mercury ndi palladium yokhala ndi OSC komanso yopanda OSC inali 0.013, 0.006 ndi 0.048, 0.030, motsatana.Njirayi imalola kutsimikiza munthawi yomweyo kwa mercury ndi palladium mu zitsanzo zopanga komanso zenizeni masanjidwewo kudalirika kwa kutsimikiza.
