2.Ụkpụrụ ngwaahịa:
A na-ekpebi ngwaahịa a site na dibenzoyl dihydrazine spectrophotometry. Mgbe agwakọtachara ihe nlele mmiri na oxidants siri ike, chromium trivalent bụ oxidized na chromium hexavalent. Hexavalent chromium na-emeghachi omume na ihe nrịbama iji mepụta mgbagwoju anya n'ihu gburugburu acidic na egosi. Onye nyocha na-achọpụta mgbanwe na agba wee gbanwee mgbanwe a ka ọ bụrụ mkpokọta uru chromium. Ọnụ ọgụgụ nke mgbagwoju agba emepụtara dabara na mkpokọta chromium.
Usoro a dabara adaba maka mmiri mkpofu na ngụkọta chromium na oke nke 0 ~ 500mg / L.
