Amazi meza kandi akonje akonje yongeyeho Anodizing
1. Kurwanya cyane umwanda hamwe nubushobozi bwiza bwo gutanga aside na alkali.
2. Igisubizo gifite ibyiza byoroshye gukora, ibintu byinshi byerekana inzira, nta mpamvu yo guhindura pH kenshi.
3. Irinde gushyirwaho ikimenyetso.
4. Nyuma yo kuvura kashe, irashobora kunoza ubukana bwimbere hamwe nuburabyo bwa aluminium.
| Ubukonje bukonje | Amazi yimana |
| 5 ~ 5.5g / L. | Kuringaniza |
| Ni2 ＋ | F- | pH | Ubushyuhe | Igihe | Gukoresha |
| 0.9 ~ 1.3g / L. | 0.4 ~ 0,6g / L. | 5.5 ~ 6.5 | 22 ~ 28 ℃ | 1μm / 1.3min | 0.9 ~ 1.5kg / T. |
1. Menya ubunini bwa Ni, F na pH, ubigire mubipimo byibikorwa
2. Tunganya pH wongeyeho acide acide acide (acide hydrofluoric acide) cyangwa dilide hydroxide ya sodium (dilute ammonia), gumana agaciro ka pH hagati ya 5.5 na 6.5.
3. Kugirango ugabanye umwanda wumuti wogeje, ugenzure ubwiza bwamazi na pH yo koga cyane, pH ntishobora kuba munsi ya 4.5.
Ubukonje bukonjesha bukonjeshwa bifunze hamwe na polybag, inshundura 5kg buri hamwe na polybag 4 muri karito, inshundura 20 kg.Kurindwa urumuri ahantu humye.
Kumenya nikel ion (Ni2 +) ibirimo
1. Suzuma intambwe.
Shushanya neza 10mL y'amazi ya sink mumashanyarazi ya mpandeshatu ya 250mL, ongeramo 50mL y'amazi, 10mL (pH = 10) ya buffer ya chloramine, agace gato ka 1% ya violetine, hanyuma unyeganyeze neza.Titrate hamwe na 0.01mol / L EDTA igisubizo gisanzwe kugeza igisubizo gihindutse kuva kumuhondo ugahinduka ibara ry'umuyugubwe nkibihe byanyuma, hanyuma wandike ingano yo gukoresha V.
2. Kubara: Nickel (g / L) = 5.869 × V × C.
V: ingano yumuti usanzwe wa EDTA ukoreshwa muri mililitiro (mL)
C: kwibumbira hamwe kwa EDTA igisubizo gisanzwe (mol / L)
1. Gutegura igisubizo cya F- gisanzwe
Solution Igisubizo gisanzwe hamwe na F- yibanze ya 5g / L: Gupima neza 11.0526g NaF (Analytical Reagent, yumisha mu ziko kuri 120 ° C kuri 2h, ubike muri desiccator hamwe nicupa ripima kugirango ukoreshe, neza na 0.0001g mugihe upima) gushonga Mu gipimo gito cy'amazi yatoboye, ohereza kuri flask ya 1000mL ya volumetric, uyunguruze ku kimenyetso, hanyuma uzunguze neza.
Solution Igisubizo gisanzwe hamwe na F- kwibanda kuri 0.1g / L: Pipette 10mL yumuti usanzwe hamwe na F- kwibanda kuri 5g / L mumashanyarazi yavuzwe haruguru mumashanyarazi ya 500mL, mumashanyarazi, hanyuma ubike mumacupa ya polyethilen.
Tegura ibisubizo bisanzwe hamwe na F- yibice bya 0.2-1 g / L nkuko byasobanuwe haruguru.
2. Gutegura imbaraga zose za Ionic Guhindura igisubizo cya Buffer (TISAB)
Fata hafi 500mL y'amazi yatoboye hanyuma ubishyire muri 1L isukuye yikirahure isukuye, ongeramo 57mL ya acide acetique glacial, hanyuma wongeremo 58.5g ya sodium chloride na 12g ya citrate ya sodium kugirango ukosore kandi ushonga burundu, hanyuma ukoreshe hydroxide ya sodium yuzuye. hindura kuri pH = 5.0 ～ 5.5, shyira kuri 1L n'amazi yatoboye.
3. F- Igishushanyo gisanzwe
Ip Pipette 2mL yumuti usanzwe hamwe nubushuhe bwa 0.1g / L mumashanyarazi ya 100mL, hanyuma ushyiremo 20mL ya TISAB ya buffer, ushyire muri magnet, ushyire kuri moteri ya magnetiki, shyiramo electrode ya ogisijeni na electrode yerekana, Nyuma yo gukurura amashanyarazi 3min, uhagarare kuri 30s, hanyuma usome ubushobozi buringaniye Ex;
Se Koresha uburyo bumwe bwo gupima agaciro gashoboka Ex yumuti usanzwe ufite F yibanda kuri 0.2 ～ 1g / L, hanyuma utondekanya kwibanda kuva hasi kugeza hejuru.Ku mpapuro zishushanyije, shushanya EF isanzwe igoramye hamwe nibishoboka E nkibisanzwe hamwe na F yibanze nka abscissa.
4. Uburyo bwo kumenya
Nukuri pipette 20mL yamazi ya sink mumazi ya 100mL, ongeramo 20mL yumubyigano wa ionic imbaraga zose (TISAB), ushyire kuri moteri ya magnetiki ya 3min, hanyuma upime neza itandukaniro rishobora gutandukana mv na electrode ya fluor.Shakisha ibirimo fluor bihuye m muri fluor-ibishobora gutandukana bisanzwe igishushanyo cya electrode.
