Leli zinga lakhiwe ngokuvumelana nezindinganiso zamanje zesiShayina zokwakheka kwamakhemikhali ethusi ne-alloy alloy imikhiqizo kanye nokucubungula imikhiqizo, okungukuthi i-GB/T468-1997 "Izingotho Zezintambo Zethusi Zokusetshenziswa Kagesi", GB/T3952-1998 "Ama-Copper Wire Billets for Electrical Use", GB/T4}617{9} "High{10}}i-Cathode Cathode Copper ehlanzekile" kanye "Ne-Standard Cathode Copper", kanye ne-GB/T5231-2001 "Ama-Copper Acutshunguliwe Nengxubevange Yethusi" Ngokusekelwe "Ekuhlanganiseni Kwekhemikhali Nokwakheka Komkhiqizo", izindinganiso kazwelonke zasekuqaleni GB/5121-1996 "Izindlela Zokuhlaziywa Kwekhemikhali/--Alloys1319 ye-Copper kanye ne-Alloys ye-319 GB ye-Copper" "Izindlela Zokuhlaziya Amakhemikhali Zethusi Elihlanzekile Le-Cathode" zabuyekezwa ngokuhlelekile. Amasu okuhlaziya athuthukisiwe asetshenziswa ukuze athathele indawo yezindlela zokuhlaziya ezinobuthi neziyingozi, futhi isizukulwane se-hydride - i-non-dispersive atomic fluorescence spectrometry isetshenziselwa ukufaka esikhundleni se-catalytic oscillopolarography ukuze kutholwe i-arsenic, i-antimony, i-selenium, i-tellurium, njll. Izindlela zokuhlaziya eziyisikhombisa ezintsha zakhiwe kanye ne-redmission aspected i-redmission aspected, kuhlanganise ne-redmission aspected e-redmission. indlela yokuhlaziya kanye nendlela yokuhlaziya i-mercury, njll.
