Ua wehewehe ʻia kahi ala spectrophotometric maʻalahi, noʻonoʻo a me ka maʻalahi no ka hoʻoholo like ʻana o ka mercury a me ka palladium.Hoʻokumu ʻia ke ʻano hana ma ka hoʻokumu paʻakikī o ka mercury a me ka palladium me Thio-Michler's Ketone (TMK) ma ka pH 3.5.ʻO nā mea āpau e pili ana i ka naʻau i hoʻopaʻa ʻia a loaʻa ka laina laina laina no ka hoʻoholo ʻana i ka mercury a me ka palladium.ʻO ka hoʻoholo like ʻana o ka hui ʻana o ka mercury a me ka palladium me ka hoʻohana ʻana i ke ʻano spectrophotometric he pilikia paʻakikī, ma muli o nā hoʻopili spectral.Ma o nā ʻano calibration multivariate e like me nā ʻāpana liʻiliʻi loa (PLS), hiki ke loaʻa i kahi kumu hoʻohālike i hoʻoponopono ʻia i nā kumu kūʻai o nā huila i hoʻohana ʻia i ka laulā calibration.ʻO ka hoʻoponopono hōʻailona Orthogonal (OSC) kahi ʻenehana hana mua i hoʻohana ʻia no ka wehe ʻana i ka ʻike pili ʻole i nā mea hoʻololi i hoʻopaʻa ʻia ma muli o ka hoʻopaʻa ʻana i ka ʻāpana kumu.ʻO OSC kahi ala preprocessing kūpono no ka calibration PLS o nā hui me ka ʻole o ka nalowale o ka hiki ke wānana me ka hoʻohana ʻana i ke ʻano spectrophotometric.Ma kēia noiʻi ʻana, hoʻokumu ʻia ke ʻano calibration i ka spectra absorption ma ka laulā 360-660 nm no 25 mau hui like ʻole o ka mercury a me ka palladium.Loaʻa i nā matrices calibration ka 0.025-1.60 a me ka 0.05-0.50 microg mL (-1) o ka mercury a me ka palladium.ʻO ka RMSEP no ka mercury a me ka palladium me OSC a me ka ʻole OSC he 0.013, 0.006 a me 0.048, 0.030.ʻO kēia kaʻina hana e hiki ai i ka hoʻoholo like ʻana o ka mercury a me ka palladium i ka synthetic a me ka matrix matrix samples maikaʻi loa o ka hoʻoholo.
