Middle Temperature Sealing Additive yog kaw nrog polybag, 5kg net txhua thiab 4 polybags hauv thawv, 20kg net txhua.Protected los ntawm lub teeb nyob rau hauv qhov chaw qhuav.
Tsawg kub polishing dab dej - txoj kev ntsuam xyuas
Yuav tsum tau reagents: 1N NaOH txheem tov ②1% phenolphthalein qhia ③ Potassium
Kev txiav txim siab ntawm nickel ion (Ni2+) cov ntsiab lus
1. Kev soj ntsuam cov kauj ruam.
Ua kom raug kos 10mL ntawm cov kua dab dej rau hauv 250mL daim duab peb sab beaker, ntxiv 50mL dej, 10mL (pH = 10) ntawm chloramine buffer, me me ntawm 1% violetine, thiab co zoo.Titrate nrog 0.01mol / L EDTA tus qauv tov kom txog rau thaum cov tshuaj hloov los ntawm daj mus rau ntshav liab raws li qhov kawg taw tes, thiab sau cov ntim ntim V.
2. Kev suav: Nickel(g/L) = 5.869 × V × C
V: qhov ntim ntawm EDTA txheem tshuaj noj hauv milliliters (mL)
C: molar concentration ntawm EDTA txheem tov (mol / L)
Kev txiav txim siab ntawm fluoride ion (F-) cov ntsiab lus
1. Kev npaj ntawm F- txheem tov
① Cov txheej txheem kev daws teeb meem nrog F- concentration ntawm 5g / L: raug hnyav 11.0526g NaF (Analytical Reagent, qhuav hauv qhov cub ntawm 120 ° C rau 2h, khaws cia rau hauv lub desiccator nrog lub raj mis hnyav rau kev siv, raug rau 0.0001g thaum hnyav) kom yaj Hauv ib qho me me ntawm cov dej distilled, hloov mus rau 1000mL ntim ntim, dilute rau lub cim, thiab co zoo.
② Standard tov nrog F- concentration ntawm 0.1g / L: Pipette 10mL ntawm cov txheej txheem tov nrog F- concentration ntawm 5g / L nyob rau hauv lub saum toj no volumetric hwj rau hauv 500mL volumetric hwj, dilute mus rau lub cim, thiab cia rau hauv ib lub raj mis polyethylene.
③ Npaj cov kev daws teeb meem nrog F- concentrations ntawm 0.2-1 g / L raws li tau piav qhia saum toj no.
2. Kev Npaj Tag Nrho Ionic Strength Adjusting Buffer Solution (TISAB)
Siv li 500mL ntawm cov dej distilled thiab muab tso rau hauv 1L huv iav beaker, ntxiv 57mL ntawm glacial acetic acid, thiab ces ntxiv 58.5g ntawm sodium chloride thiab 12g ntawm sodium citrate los kho thiab yaj tag, thiab ces siv analytically ntshiab sodium hydroxide rau. kho rau pH = 5.0 ~ 5.5, dilute rau 1L nrog dej distilled.
2. F- Standard nkhaus daim duab
① Pipette 2mL ntawm cov qauv kev daws teeb meem nrog cov ntsiab lus ntawm 0.1g / L rau hauv 100mL yas beaker, tom qab ntawd ntxiv 20mL TISAB tsis siv tshuaj, muab tso rau hauv cov hlau nplaum, do rau ntawm cov hlau nplaum sib nqus, ntxig oxygen electrode thiab siv electrode raws li, Tom qab electromagnetic stirring rau 3min, sawv ntsug rau 30s, thiab nyeem qhov sib npaug ntawm Ex;
②Siv tib txoj kev los ntsuas qhov muaj peev xwm tus nqi Ex ntawm cov qauv kev daws teeb meem uas nws F concentration yog 0.2 ~ 1g / L, thiab txheeb cov concentration ntawm qis mus rau siab.Ntawm daim duab kos duab, kos EF tus qauv nkhaus nrog lub peev xwm E raws li kev tswj hwm thiab F concentration raws li abscissa.
Ua kom raug pipette 20mL ntawm lub dab dej ua kua rau hauv 100mL beaker, ntxiv 20mL ntawm tag nrho cov ionic zog buffer (TISAB), do ntawm ib tug sib nqus stirrer rau 3min, thiab ncaj qha ntsuas qhov sib txawv mv nrog ib tug fluorine electrode.Nrhiav cov ntsiab lus fluorine sib xws m hauv fluorine cov ntsiab lus-muaj peev xwm sib txawv tus qauv electrode daim duab.
