1.Product Overview:
Chemical oxygen demand (COD) inoreva kuwanda kweokisijeni inopedzwa neoxidants painookisisa organic uye inorganic inodzikisa zvinhu mumasampuli emvura ane akasimba oxidants mune mamwe mamiriro. COD zvakare indekisi yakakosha inoratidza huwandu hwekusvibiswa kwemvura neorganic uye inorganic kuderedza zvinhu.
Iyo analyzer inogona kushanda otomatiki uye nekuenderera kwenguva yakareba pasina kuenda zvinoenderana nesaiti marongero. Inoshandiswa zvakanyanya mumaindasitiri ekusvibisa sosi inorasa mvura yetsvina, maindasitiri maitiro etsvina, maindasitiri emvura yekuchenesa mvura yetsvina, masuwage emvura yekuchenesa mvura yetsvina uye zvimwe zviitiko. Zvinoenderana nekuoma kwemamiriro ekuedzwa kwesaiti, iyo inoenderana pretreatment system inogona kusarudzwa kuti ive nechokwadi chekuti maitiro ebvunzo akavimbika, mhedzisiro yebvunzo ndeyechokwadi, uye inozadzisa zvizere zvinodiwa zvezviitiko zvakasiyana.
2.Product Principle:
Sampuli dzemvura, potassium dichromate digestion solution, sirivheri sulfate solution (silver sulfate secatalyst inogona kuwedzerwa kuti oxidize linear aliphatic compounds zvinobudirira) uye concentrated sulfuric acid musanganiswa inopisa kusvika 175 ℃. Rudzi rwezvakagadzirwa organic mu dichromate ion oxidation mhinduro ichachinja. Iyo analyzer inoona kushanduka kwemavara uye inoshandura shanduko muCOD kukosha uye inoburitsa kukosha.Kuwanda kweiyo dichromate ion inopedzwa yakaenzana nehuwandu hweoxidizable organic matter, iyo COD.
