Iimpawu zeMveliso

1. Ukuchasana okugqwesileyo kokungacoceki kunye nomthamo olungileyo wokuphazamisa kwi-asidi kunye ne-alkali.

2. Isisombululo sineenzuzo zokulula ukusebenza, uluhlu olubanzi lweeparamitha zenkqubo, akukho mfuneko yokulungelelanisa i-pH rhoqo.

3. Thintela ukutywina kungenzeki.

4. Emva kokunyangwa kokutywinwa, kunokuphucula ukuqina komphezulu kunye negloss yeeprofayili ze-aluminium.

0.9~1.3g/L	0.4~0.6g/L	5.5~6.5	22 ~ 28℃	1μm/1.3min	0.9~1.5kg/T

Ukugcinwa kwesisombululo

1. Qinisekisa ugxininiso lwe-Ni, F kunye ne-pH, zenze zibe phakathi koluhlu lweeparamitha zenkqubo
2. Lawula i-pH ngokudibanisa i-acetic acid edibeneyo (i-dilute hydrofluoric acid) okanye i-dilute i-sodium hydroxide (i-dilute ammonia), gcina ixabiso le-pH phakathi kwe-5.5 kunye ne-6.5.
3. Ukunciphisa ungcoliseko lwesisombululo sokuhlambela, lawula umgangatho wamanzi kunye ne-pH yebhafu yokuhlamba ngokungqongqo, i-pH ayikwazi ngaphantsi kwe-4.5.

Ukupakishwa

I-Cold Seal Additive itywinwa nge-polybag, i-5kg net nganye kunye ne-4 polybags kwibhokisi, i-20kg net nganye.Ikhuselwe ekukhanyeni kwindawo eyomileyo.

Indlela yoVavanyo

Ukumiselwa komxholo we-nickel ion (Ni2 +).
1. Amanyathelo ovavanyo.
Zoba ngokuchanekileyo i-10mL yolwelo lwe-sink kwi-250mL yebhika engunxantathu, yongeza i-50mL yamanzi, i-10mL (pH=10) ye-chloramine buffer, umlinganiselo omncinci we-1% ye-violetine, kwaye ungcangcazele kakuhle.I-Titrate kunye ne-0.01mol / L isisombululo esiqhelekileyo se-EDTA de isisombululo sitshintshe ukusuka kumthubi ukuya kwimfusa njengendawo yokuphela, kwaye urekhode umthamo wokusetyenziswa V.
2. Ukubala: Nickel(g/L)=5.869 × V × C
V: umthamo wesisombululo esiqhelekileyo se-EDTA esisetyenziswe kwiimililitha (mL)
C: Uxinzelelo lwe-molar lwesisombululo esisemgangathweni se-EDTA (mol/L)

Ukumiselwa komxholo weFluoride Ion (F-).

1. Ukulungiswa kwesisombululo se-F-standard
① Isisombululo esisemgangathweni kunye ne-F-concentration ye-5g / L: Ukulinganisa ngokuchanekileyo i-11.0526g NaF (I-Analytical Reagent, eyomileyo kwi-oven kwi-120 ° C ye-2h, igcina kwi-deiccator kunye nebhotile yokulinganisa ukusetyenziswa, ngokuchanekileyo kwi-0.0001g xa ulinganisa) ukunyibilika Kwixabiso elincinci lamanzi adibeneyo, udlulisele kwi-flask ye-volumetric ye-1000mL, nciphisa uphawu, kwaye ugubungele kakuhle.
② Isisombululo esisemgangathweni kunye ne-F-concentration ye-0.1g / L: I-Pipette 10mL yesisombululo esisemgangathweni kunye ne-F-concentration ye-5g / L kwi-flask ye-volumetric engentla kwi-flask ye-volumetric ye-500mL, i-dilute kwi-mark, kwaye igcine kwibhotile ye-polyethylene.
③ Lungiselela izisombululo ezisemgangathweni kunye ne-F-concents ye-0.2-1 g/L njengoko kuchazwe ngasentla.

2. Ukulungiswa kweTotal ye-Ionic Strength Adjusting Buffer Solution (TISAB)
Thatha malunga ne-500mL yamanzi adibeneyo kwaye uwafake kwi-beaker yeglasi ecocekileyo eyi-1L, yongeza i-57mL ye-glacial acetic acid, uze wongeze i-58.5g ye-sodium chloride kunye ne-12g ye-sodium citrate ukulungisa nokunyibilika ngokupheleleyo, kwaye usebenzise i-sodium hydroxide ecocekileyo ngokuhlalutya. lungelelanisa i-pH=5.0～5.5, dilute kwi-1L ngamanzi adibeneyo.

3. F- Umzobo oqhelekileyo wegophe
① I-Pipette 2mL yesisombululo esisemgangathweni esinogxininiso lwe-0.1g/L kwibhekile yeplastiki eyi-100mL, emva koko wongeze i-20mL isisombululo sesithinteli se-TISAB, faka umazibuthe, ushukume kwi-stirrer yamagnetic, faka i-electrode ye-oksijini kunye ne-electrode yereferensi ngokulandelelana, Emva kokuvuselela i-electromagnetic for 3min, yima 30s, kwaye ufunde equilibrium enokubakho Ex;
②Sebenzisa indlela efanayo yokulinganisa ixabiso elinokubakho le-Ex yesisombululo esisemgangathweni esinogxininiso lwe-F yi-0.2～1g/L, kwaye uhlele ugxininiso ukusuka phantsi ukuya phezulu.Kwiphepha legrafu, zoba i-curve esemgangathweni ye-EF kunye ne-E enokubakho njengolungelelaniso kunye nogxininiso lwe-F njenge-abscissa.

4. Inkqubo yokuzimisela
Ngokuchanekileyo i-pipette i-20mL yolwelo lwe-sinki kwibhika eyi-100mL, yongeza i-20mL yesithinteli samandla e-ayoni sisonke (TISAB), ushukume kwi-magnetic stirrer kangange-3min, kwaye ulinganise ngokuthe ngqo umahluko onokubakho we-mv nge-electrode ye-fluorine.Fumana isiqulatho sefluorine esihambelanayo m kumxholo wefluorine-umehluko onokuthi ubekho umgangatho wedayagramu ye-electrode.
