Raws li cov khoom siv raw khoom sib txawv, cov txheej txheem tseem ceeb ntawm kev sib txuastrisodium citrate hmoovyog:

Txoj Kev 1: citric acid + sodium hydroxide method

Qhov no kuj yog qhov ntxov tshaj plaws kev tshawb fawb thiab kev loj hlob ntawm ntau lawm technology. Citric acid yog yaj nyob rau hauv dej thiab ntxiv rau sodium hydroxide tov los tsim neutralization cov tshuaj tiv thaiv thiab ua kom muaj cua sov ntau. Cov khoom tiav yog tau los ntawm kev pom, concentration, crystallization thiab ziab. Cov txheej txheem yog yooj yim thiab purity ntawm cov khoom yog zoo; Qhov tsis zoo yog tus nqi ntau lawm. Tam sim no nws tsuas yog siv los npaj cov khoom siv hauv chav kuaj.

Txoj kev 2: citric acid + soda tshauv txoj kev

Txoj kev txhim kho ntawm txoj kev nruab nrab muaj qhov zoo ntawm kev yuav khoom yooj yim, khaws cia zoo thiab cov nqi qis ntawm cov dej qab zib tshauv ua raw khoom; Nws yog ib txoj kev tsim khoom uas feem ntau siv los ntawm cov tuam txhab lag luam.

Txoj Kev 3: citric acid + baking soda method

Txoj kev no yog ib txoj hauv kev txhim kho kev npaj rau cov khoom qab zib tshauv uas tsis haum rau kev lag luam kws tshuaj. Txoj kev no siv cov khoom zoo sodium bicarbonate, uas yog yaj nyob rau hauv dej raws li tus nqi, neutralized nrog citric acid, thiab ua tiav los ntawm concentration thiab crystallization los npaj cov tshuaj qib sodium citrate. Nws yog tus cwj pwm los ntawm cov tshuaj tiv thaiv me me, cov khoom lag luam zoo thiab cov txheej txheem ua haujlwm zoo. Nws yog tsuas yog siv nyob rau hauv ib co chaw ua tshuaj.

Txoj Kev 4: calcium citrate + dej qab zib txoj kev

Nyob rau hauv txoj kev no, calcium citrate thiab dej qab zib tshauv yog tov los tsim cov tshuaj tiv thaiv ob zaug decomposition, thiab cov tshuaj insoluble raug lim tawm kom tau txais sodium citrate. Lub purity ntawm cov khoom tsis zoo thiab cov txheej txheem ua haujlwm ntev. Ob peb xyoos dhau los, nws tau tshaj tawm tias los ntawm kev kho tus nqi pH ntawm kev sib xyaw ua ke, cov txheej txheem ntws tau yooj yim, cov nqi tsim khoom raug txo, thiab cov khoom zoo dua tau txais.

Qee tus neeg siv txoj kev pauv pauv los tsim sodium citrate. Lub fermentation supernatant yog pauv nrog ion resin, thiab ces cov adsorbed citric acid yog eluted nrog sodium hydroxide tov. Cov tau txais sodium ntsev tov yog concentrated thiab crystallized kom tau txais sodium citrate khoom. Txoj kev no tsis muaj kuab paug thiab tus nqi qis.
