Ha ho sebetsana le asiti ea litšila, mekhoa eo e ka khetholloang e kenyelletsa tšoaro ea letsoai, mokhoa oa ho se jelle ha 'mele, mokhoa oa ho khethula, mokhoa oa ho arohana oa membrane, jj.
1. Setsi sa ho hlakola
Seo ho thoeng ke salting ke ho sebelisa metsi a mangata a letsoai ho phatsima hoo e ka bang le likotsi tsohle tsa manyolo ho asiti ea litšila. Leha ho le joalo, mokhoa ona o tla hlahisa hydrochloric acid mme o ama ho hlaphoheloa le ts'ebeliso ea asiti ea asiti ea litšila ka sodium Bisfate e ile ea ithutoa.
Asiti ea matla a senya e na le litlolo tsa sesepa le litlolo tse fapaneng tsa bokoang ke 6-chlorotoluene-4 sulfenic acid Mokhoa oa ho emisa ke ho sebelisa metsi a mangata a letsoai a nang le mafura a letsoai ho hofihlella lintho tsohle tse phelang ho asiti ea litšila. Mokhoa oa ho ngola ka letsoai o ke ke oa tlosa litšila tse fapaneng tse fapaneng feela a asiti, empa hape a fole sulfuric acid ho kenya tlhahiso le matla le matla.
2. Mokhoa oa ho roa
Mokhoa oa ho roka o sebelisoa ho acid e tloaelehileng e kang hydrochloric acid, e arohaneng le tharollo ea ho khutlisa phello.

Molao-motheo oa mantlha oa ho phekola litšila tsa li-acid acid acid ea acid ea li-acid tse tsoang ho acif acic acic ho fihlela li-acif e acid ea acid le letsoai.
6. Mokhoa oa ho arohana oa membrane
Bakeng sa lino tse silafetseng tsa acidic, mokhoa oa tšoaro e matla ea membrane o joalo ka ho fokola le elektronisisis. Pholoso ea ho phonyoha ha asiti ea litšila haholo-holo e amohela molao-motheo oa ho ba le bo fapaneng, e khannoang ke phapang ea mohopolo. Sesebelisoa sohle se entsoe ka membrane e nang le li-dialysis, poleiti e ntle, poleiti ea pole, e matla, 'me e fihlela karohano ea metsi ka metsing.
7. Mokhoa oa ho futhumatsa oa crystallization
Mokhoa oa ho pholisa o futhumatsang ke mokhoa oa ho fokotsa mocheso oa tharollo le ho fafatsa tharollo ea tharollo. E sebelisoa ts'ebetsong ea kalafo ea acid acid ea asiti ea asiti ea litšila e folile ho khutlisa litlhoko tsa acid tse kopanang le litlhoko tsa acid mme li ka sebelisoa hape. Mohlala, asiti ea litšila e senyehileng ho tloha ts'ebetsong ea ho hlatsoa e nang le acnyl Kamora ho tlosoa ha tšireletso e feretsoeng ka ho teneha, acid e ka khutlisetsoa mokhoeng oa ho kenya letsoho bakeng sa ho tsoela pele ho sebelisoa.
Crystallization e futhumatsang e na le lits'ebetso tse ngata tsa indasteri, tse bontšitsoeng mona li kopantsoe ke ts'ebetso ea tšepe. Ts'ebetsong ea tšepe le ts'ebetso ea mochini, tharollo ea sulfuric acid e tloaetse ho tlosa mafome holim'a tšepe. Ka hona, ho nyahlatsa asiti ea litšila a ka fokotsa litšenyehelo haholo 'me a sireletsa tikoloho. Crystallization e se e sebelisoa indastering ho fihlela ts'ebetso ena.
8. Mokhoa oa oxidation
Mokhoa ona o sebelisitsoe ka nako e telele, 'me molao-motheo ke ho lahla litšila tsa manyolo, joalo ka ha ho katoa le li-acid tse litšila tse ka hloekisitsoeng ebe se hlaphoheloa. Boholo ba oxida ba sebelisoa ke hydrogen peroxide, nitric acid acid, hypochlous acid, nitrate, ozone, ozone, Ozone, Ozone, Ozone Oxidizer e 'ngoe le e' ngoe e na le melemo le mefokolo ea eona.
