Murexide yog metal indicator for Ca, Co, Cu, Ni, Th, and rare earth metals; nws kuj yog ib tug colorimetric reagent rau calcium thiab tsawg ntiaj teb hlau. Murexide yog me ntsis soluble hauv dej, cawv, thiab ether. … Kev kuaj xyuas cov calcium yog pH 11.3, qhov siab tshaj plaws wavelength 506 nm thiab kuaj pom ntau yam 0.2-1.2 ppm.
Vim li cas murexide yog qhov ntsuas tsim nyog?
Vim li cas Murexide yog qhov ntsuas tsim nyog? … Qhov taw qhia siv yog murexide uas yog xim txawv thaum freq piv rau nws cov xim thaum nws txuas rau Ni2 ions. Murexide yog qhov ntsuas tsim nyog txij li nws khi tsawg zog rau Ni2ions dua li EDTA.
PH ntau ntawm murexide ntsuas yog dab tsi?
Murexide kuj tseem siv los ua cov tshuaj pleev xim rau kev ntsuas cov calcium thiab cov hlau tsis tshua muaj hauv ntiaj teb; rau calcium, pH xav tau yog 11.3, kev tshawb pom nyob ntawm 0.2-1.2 ppm, thiab qhov siab tshaj plaws absorbance wavelength yog 506 nm.
Koj ua qhov ntsuas murexide li cas?
A av sib tov ntawm cov hmoov dye thiab sodium chloride (NaCl) muab ib daim ntawv ruaj khov ntawm qhov taw qhia. Npaj los ntawm mixing 200 mg murexide nrog 100 g khoom NaCl thiab sib tsoo cov sib tov rau 40 mus rau 50 mesh Titrate tam sim tom qab ntxiv qhov taw qhia vim nws tsis ruaj khov nyob rau hauv alkaline tej yam kev mob.
Qhov ntsuas twg yog siv hauv EDTA titration?
EDTA luv luv rau ethylenediaminetetraacetic acid. Ib xim xiav hu ua Eriochrome Black T (ErioT) yog siv los ua qhov taw qhia. Qhov xiav dye no kuj tsim ib txoj hauv kev nrog cov calcium thiab magnesium ions, hloov xim ntawm xiav mus rau liab hauv cov txheej txheem. Cov dye-hlau ion complex tsis ruaj khov dua li EDTA-hlau ion complex.
