Ithusi liphakathi kwezinsimbi zokuqala ezisetshenziswa ngabantu. Njengenye yezinsimbi zethusi ezincibilikayo ezibaluleke kakhulu, i-copper sulfate ibilokhu ihambisana nokuthuthukiswa kwezimayini, ezolimo kanye nokukhiqiza amakhulu eminyaka. I-copper sulfate evame ukusetshenziswa embonini, kwezolimo kanye nokufaka i-electroplating ngokuvamile ibhekisela ku-i-pentahydrate ye-copper sulfate (CuSO₄·5H₂O), i-blue crystalline solid eyaziwa ngokuthi i-chalcanthite. I-Anhydrous copper sulfate iyimpuphu emhlophe enamandla okumunca amanzi, futhi lezi zinhlobo ezimbili zihluka kakhulu ngezakhiwo ze-physicochemical kanye nezimo ezisebenzayo. Ayisebenzi nje kuphela njengendawo evamile ye-copper hydrometallurgy kanye nokuhluzwa kwe-electrolytic, kodwa futhi njengezinto zokusetshenziswa ezivuthiwe zamakhemikhali ezolimo, i-electroplating kanye nokwelashwa kwamanzi. Eminyakeni yamuva nje, iqhutshwa yintuthuko ezintweni ezintsha kanye nemikhakha yamandla e-hydrogen, leli khemikhali elidala liye landisa njalo imingcele yalo yokusebenzisa. Okwamanje, izingozi zemvelo nezempilo ezibangelwa ithusi eliningi zibeka imithetho eqinile ekusetshenzisweni kwalo.
Ngaphakathi komkhakha wezimayini, ukusetshenziswa kwe-copper sulfate kwaqala ezikhathini zasendulo, kodwa impumelelo yayo yezimboni yafika ngekhulu le-19. Ngawo-1860, uJames B. Elkington wathola ilungelo lobunikazi lokuhweba lokucwenga ithusi nge-electrolytic futhi wayala isitshalo sokuqala esisebenza ngempumelelo eWales cishe ngo-1870. Le nqubo yokucwenga i-electrolytic isebenzisa ithusi elingacwengekile njenge-anode kanye nethusi elihlanzekile njenge-cathode, kanye nesisombululo se-copper sulfate sulfuric acid esisebenza njenge-electrolyte. Uma inikwe amandla, ithusi lensimbi elivela ku-anode liyancibilika libe yisisombululo, bese ama-ion ethusi ancishiswa bese efakwa ku-cathode ukuze akhiqize ithusi le-electrolytic elingafika ku-99.99% ubumsulwa. Lokhu kusungulwa kobuchwepheshe kwaguqula ukucwenga ithusi, kunqobe ukushiyeka kwe-pyrometallurgy yendabuko njengokusetshenziswa kwamandla aphezulu kanye nobumsulwa bomkhiqizo obulinganiselwe. Engxenyeni enkulu yekhulu lama-20, ukucwenga i-electrolytic kwabusa ukuhlanzwa kwethusi okuyinhloko, kanti i-copper sulfate sulfuric acid electrolyte yahlala iyindawo yayo eyinhloko.
Ngaphezu kwalokho, i-copper sulfate iyinto ebalulekile ekukhishweni kwe-hydrometallurgical copper. I-copper oxide ore esezingeni eliphansi ixutshwa ne-sulfuric acid encibilikisiwe ukuze kuncibilikiswe i-copper ibe yisisombululo ngesimo se-copper sulfate. Kunezindlela ezimbili eziyinhloko zokubuyisa i-copper okulandelayo: imisebenzi emincane evamile isebenzisa ukuqinisa insimbi ukuze kukhiqizwe i-sponge copper, kuyilapho izincibilikisi ezinkulu ze-hydrometallurgical zanamuhla zisetshenziswa kabanzi.ukukhipha i-solvent – ukuwina i-electro (SX‑EW)Le nqubo ikhipha futhi igxilise ithusi ekuleachate ngokukhetha ngaphambi kokuthola ithusi eliyi-cathode ngogesi. Kusukela yasungulwa ngezimboni ngasekupheleni kwawo-1960, i-SX‑EW ikhule ngokushesha ngezindleko zokusebenza eziphansi kakhulu kune-iron cementation, yaba ubuchwepheshe obudumile bokucubungula i-ore yethusi esezingeni eliphansi.
Kwezolimo, i-copper sulfate iyinto ebalulekile yezolimo yokulawula izinhlobo eziningi zezifo ezibangelwa yi-fungus kanye ne-bacterial plant. Iyisithako esiyinhloko sokulungiselela ingxube ye-Bordeaux, esetshenziswa kabanzi ezivinini nasezingadini zezithelo ukulwa nezifo ezifana ne-downy mildew. Kuncike emikhawulweni yesilinganiso esisemthethweni, ingafakwa futhi ekudleni kwezilwane. I-Copper iyinto ebalulekile yokulandelela emfuyweni; noma kunjalo, umkhuba wokukhuthaza ukukhula kwe-copper ephezulu uthwala izingozi ezinkulu zemvelo, okubangela imikhawulo eqinile yokuhlushwa ephoqelelwe emazweni amaningi.
Emikhakheni yobuciko kanye nobuciko, i-copper sulfate iyigugu ngenxa yombala wayo oluhlaza okwesibhakabhaka ohlukile. Isebenza njenge-mordant ekudayini izindwangu ukuze ikhiqize amadayi aluhlaza okwesibhakabhaka anombala osheshayo omuhle. Ekukhiqizweni kwe-ceramic, ixutshwa ibe yi-glaze ukuze ikhiqize ama-glaze aluhlaza okwesibhakabhaka naluhlaza ngemva kokushisa. Abaculi banamuhla basebenzisa futhi ukusebenza kwayo kwamakhemikhali kanye nezici zombala ukudala imisebenzi ebonakalayo eyingqayizivele.
Embonini ye-electroplating, i-copper sulfate iyisithako esiyinhloko sokufaka i-acid copper plating. Izinto zokusebenza ezenziwe ngensimbi, i-zinc alloy kanye nezinye izinto ezisetshenziswayo zicwiliswa ebhavini lokufaka i-plating. Ngaphansi kwamandla kagesi, ama-ion ethusi afakwa ku-substrate ukuze akhe i-coating yethusi yokuvikela ukugqwala kanye nezinjongo zokuhlobisa, esetshenziswa kakhulu ezingxenyeni zezimoto, izingxenye ze-elekthronikhi kanye nehadiwe yokuhlobisa. I-copper sulfate ecwengisiswe ngobumsulwa obuphezulu inciphisa ukungcola kwensimbi kanye nezinto eziphilayo ezixazululweni zokufaka i-plating, ivimbela ngempumelelo amaphutha okufaka imigodi, imigodi kanye nokushintsha kombala okumnyama. Iqinisekisa ukujiya okufanayo kokufaka i-coating, amandla aphezulu okuphonsa, futhi ithuthukisa ukuhanjiswa kukagesi, ukuguquguquka kanye namandla okudonsa ethusi elifakiwe.
Ekuhlanzweni kwamanzi, i-copper sulfate isebenza kakhulu njenge-bactericide kanye ne-algaecide yokunciphisa ukuqhakaza kwe-cyanobacteria emachibini nasemadamini. Ilimaza i-chlorophyll ku-cyanobacteria futhi ivimbela i-photosynthesis, igweme ukuncipha komoya-mpilo okubangela ukufa okukhulu kwezinhlanzi nezimfanzi. I-Copper sulfate ibilokhu isetshenziswa njenge-algaecide yamanzi ahlanzekile kusukela ngawo-1950. Kodwa-ke, ama-ion e-copper anobuthi emvelweni, ngakho-ke umthamo kumele ulawulwe ngokuqinile ukuze kutholakale ibhalansi phakathi kokusebenza kahle kokwelashwa kanye nokuphepha kwemvelo yasemanzini.
Naphezu kokusebenza kwayo kabanzi, i-copper sulfate inezingozi zemvelo nezempilo ezingenakucatshangelwa ngenxa yemvelo yayo yensimbi enamandla. I-copper eningi ifaka ubuthi ezintweni eziphilayo zasemanzini futhi icindezela umsebenzi wezinto eziphilayo zasemhlabathini. Ukusetshenziswa kwesikhathi eside kwengxube ye-Bordeaux kuholela ekuqongeleleni kwethusi enhlabathini futhi kuvimbele ukukhula kwezitshalo. Ukweqisa umthamo ekuhlanzweni kwamanzi kubulala izinhlanzi ne-plankton, okuphazamisa ibhalansi yemvelo yasemanzini.
I-Copper sulfate inobuthi kubantu. Ukungenisa inani elikhulu kubangela ukuhlanza, uhudo kanye nokulimala kwesibindi, futhi kungaba yingozi ezimweni ezimbi kakhulu. Ukuhogela isikhathi eside uthuli lwe-copper sulfate kuyacasula indlela yokuphefumula futhi kungabangela ukungezwani kwesikhumba. Ngakho-ke, ukusetshenziswa okujwayelekile, okuphephile nokulawulwayo kuhlala kuyinto eza kuqala embonini yonke.
Ukuqinisa imithethonqubo yezemvelo kanye nokuguquka kwamandla kuqhuba ukuthuthukiswa okuqhubekayo okubhekiswe ezinqubweni zokonga amandla kanye nokukhiqiza okuhlanzekile kwe-copper sulfate, ngemikhiqizo ethambekele ekuhlanzekeni okuphezulu kanye namazinga enziwe ngokwezifiso. Njengesisekelo sokudla sokukhiqiza i-cupric oxide, i-copper carbonate eyisisekelo kanye nosawoti wethusi, kuhlanganiswe nokukhula kwesidingo esivela ekufakweni kwe-electroplating, amabhethri, amakhemikhali ezolimo kanye nezimboni zamandla amasha, leli khemikhali elivivinywe isikhathi eside lamukela amathuba amasha entuthuko. Isiqondiso esiyinhloko somkhakha ozayo sisekusebenziseni ubuchwepheshe obusha ukuze kulinganiswe imikhawulo yezinsiza kanye nezingcindezi zemvelo, kuvulwe inani lokusetshenziswa eliphezulu kanye nokugcina amandla phakathi kokuhlelwa kabusha kwezintambo zezimboni zomhlaba wonke.
