Momwe COBE YOPHUNZIRA IZI IMAPHUNZITSIDWA MU TOP

ACOD YOPHUNZIRAOpangidwa ndi Ariaren nthawi zambiri amagwiritsidwa ntchito poyesa mankhwala oxygen akufuna (Cod) kuyesedwa, ndi kuyesa kwa cod kumagwiritsa ntchito makoko ena kuti atseke zinthu (kuphatikiza organics) m'madzi. Kutentha ndi kutentha nthawi, kuyesayesa kumafuna njirayi nthawi zambiri kumagwiritsidwa ntchito ngati muyeso wa oderera opangidwa.

Mankhwala oxygen amafuna bwino kuti awonetse zoipitsa zoipitsa mu madzi otayika mafakitale okhala ndi chonade ndi zitsulo zolemera. Kuyesa kwa COD kungayankhe mwachangu pakusintha mikhalidwe isanachitike. Ndi Airiren COD YOPHUNZIRA, wogwiritsa ntchito aliyense amatha kupezeka mosavuta komanso mosavuta.

Kupitilira apo, kufunika kwa oxgen ndikofunikira kwambiri kuwunika mtundu wa madzi onyansa ndikuwataya madzi asanatulutse. Kuyesa kwamankhwala kwa oxygen (cod) kumatha kuneneratu kufunika kwa madzi osungirako zinyalala, omwe angagwiritsidwe ntchito kuyang'anira ndi kuwongolera zowongolera ndikuwunika magwiridwe antchito othandizira.

Pazinthu zomwe zatsatanetsatane wa oxygen zimafuna kuyesa, choyamba onjezani 2 ml ya madzi kapena madzi atsopano ku 16mm COD YOPHUNZIRA okhala ndi mankhwala othandizira komanso othandizira. Phimbani chubu ndi polypropyynene yolembedwa polyproplene chubu ndikutenthetsa mu digishi ya chipika cha 150 ° C kwa maola awiri. Chubu cha COD chomwe chimapangidwa ndi Ariaren chili ndi zida zolondola.

Ndikofunika kutsindika kuti izi COD YOPHUNZIRA imatha kugwiritsidwa ntchito kamodzi ndipo sangagwiritsenso ntchito. Gwiritsani ntchito cod tultetests zimakhala ndi sulfuric acid ndi mankhwala ena, motero ma reagents ayenera kugwiritsidwa ntchito mosamala. Mankhwala mu mapaipi ayenera kutaya malinga ndi zofunikira zaboma. Machubu awa adadutsa chitsimikizo cha SGC.
