Isidingo somoya-mpilo wamakhemikhali siwukuhlola okubalulekile kokuhlola ikhwalithi yamanzi alahlwayo kanye namanzi angcolile ngaphambi kokuba akhishwe. Ukuhlolwa kweChemical Oxygen Demand (COD) kubikezela isidingo somoya-mpilo kumfucumfucu futhi isetshenziselwa ukuqapha nokulawula okuphumayo, kanye nokuhlola ukusebenza kwezitshalo zokwelashwa. Umthelela wokuchitheka kwamanzi angcolile noma angcolile emanzini atholwayo ubikezelwa ngesidingo sawo somoya-mpilo. Lokhu kungenxa yokuthi ukukhishwa komoya-mpilo emanzini emvelo kunciphisa amandla awo okulondoloza impilo yasemanzini. Ngakho-ke uhlolo lwe-COD lwenziwa njengenjwayelo kulabhorethri yezinsiza zamanzi nezinkampani zezimboni.

I-Aijiren COD Test Tube incane ngosayizi futhi ilula ngesisindo. Ingahlolwa ngaphandle kwanoma iyiphi enye impahla yaselabhorethri kanye nochwepheshe; kuthatha imizuzu engu-3-5 kuphela ukuhlola isampula, ngaphandle kwezisetshenziswa ezengeziwe noma amathuluzi, futhi kulula ukuyisebenzisa.

Imininingwane Yokuhlolwa Kwesidingo Se-Chemical Oxygen:

U-2mL wesampula wamanzi noma we-watse wengezwa eshubhuni yengilazi engu-16mm equkethe into evuselela ukugaya ukudla kanye ne-catalyst. Ishubhu imbozwe nge-polypropylene, ikepisi elayishiwe ye-PTFE futhi ishisiswe ku-block digester ku-150C amahora angu-2. I-chromium ye-Hexavalent ewolintshi yehliswa ibe yi-chromium e-trivalent eluhlaza okwesibhakabhaka. Ibanga lokuhlaziya lendlela ye-spectrophotometric ngu-5-150ppm (kukalwa ku-420nm).

I-Aijiren ibambe iqhaza ekukhiqizeni ishubhu yokuhlola ye-COD ene-Caps iminyaka engaphezu kweshumi, sinolwazi olucebile ngokuphelele nezinqubo ezijwayelekile zokukhiqiza ishubhu yokuhlola ye-COD enekepisi, futhi singaqinisekisa ikhwalithi ephezulu yeshubhu yokuhlola ye-COD ekhiqizwa i-Aijiren ngentengo efanelekile.
