Isihlalutyi seCOD esikwi-intanethi
Umgaqo wokuFumanisa
Yongeza isixa esaziwayo sesisombululo se-potassium dichromate kwisampuli yamanzi, kwaye usebenzise ityuwa yesilivere njenge-catalyst kunye ne-mercury sulfate njenge-arhente yokufihla kwindawo enamandla ene-asidi. Emva kokusabela kokugaya okunobushushu obuphezulu kunye noxinzelelo oluphezulu, fumana ukufunxwa kwemveliso kwinqanaba elithile. Ngokomthetho kaLambert Beer, kukho ulwalamano oluchanekileyo phakathi komxholo wemfuno ye-oksijini yeekhemikhali emanzini kunye nokufunxwa, uze umisele uxinano lwemfuno ye-oksijini yeekhemikhali emanzini. Qaphela: Kukho ubunzima bokuxovula izinto ezifana ne-aromatic hydrocarbons kunye ne-pyridine kwisampuli yamanzi, kwaye ixesha lokugaya linokwandiswa ngokufanelekileyo.
