Hexavalent Chromium Umgangatho waManzi kwi-Intanethi ngokuzenzekela ukubeka iliso kuMfanekiso oboniswayo

UmGangatho waManzi we-Chromium Hexavalent kwi-Intanethi ngokuzenzekelayo

Inkcazelo emfutshane:

I-analyzer inokuthi isebenze ngokuzenzekelayo kwaye ngokuqhubekayo ingajongwanga ixesha elide ngokuhambelana nendawo, kwaye isetyenziswa ngokubanzi kumthombo wongcoliseko lwemizi-mveliso ukukhupha amanzi amdaka, inkqubo yamanzi amdaka enkqubo yoshishino, ugutyulo lwamanzi amdaka kwimizi-mveliso, ugutyulo lwamanzi amdaka kamasipala kunye nezinye izihlandlo. Ngokobunzima beemeko zovavanyo lwentsimi, inkqubo yonyango ehambelanayo inokukhethwa ukuze kuqinisekiswe ukuthembeka kwenkqubo yovavanyo kunye nokuchaneka kweziphumo zovavanyo, kwaye ihlangabezane ngokupheleleyo neemfuno zentsimi zezihlandlo ezahlukeneyo.

Iinkcukacha zeMveliso

Iithegi zeMveliso

1.Isishwankathelo seMveliso:

2.Umgaqo weMveliso:

Le mveliso imiselwe yi dibenzoyl dihydrazine spectrophotometric colorimetric indlela. Emva kokuxuba isampuli yamanzi kunye nomlawuli, i-chromium ene-hexavalent iphendula kunye nesalathisi ukwenza i-complex enemibala kwindawo ene-acidic kunye nobukho besalathisi. I-analyzer ibona utshintsho lombala kwaye iguqule olu tshintsho lube yi-hexavalent chromium value output. Ubungakanani bemibala entsonkothileyo eveliswayo bulingana nobungakanani be-chromium enehexavalent.

Le ndlela ifanelekile kumanzi amdaka anehexavalent chromium kuluhlu lwe-0 ~ 30mg/L.
