Ukulinganiswa Okuqhubekayo kweAmmonia Kumanzi Omlambo

Umgangatho wamanzi omlambo uvavanywa yi-Environment Agency ngenkqubo yoVavanyo loMgangatho Jikelele (i-GQA) kwaye kubalulekile ukuba iikhemikhali ezinokuba yingozi emlanjeni zilawulwe. I-Ammonia sisondlo esibalulekileyo kwizityalo kunye ne-algae ezihlala emanzini omlambo. Nangona kunjalo, xa ubushushu bomlambo butshintsha, i-ammonia ene-ionized itshintsha ibe yigesi ye-ammonia engeyiyo i-ionized. Oku kuyingozi kwiintlanzi nakwezinye izinto eziphilayo zasemanzini emlanjeni, ngoko ke kubalulekile ukujonga rhoqo amanqanaba e-ammonia.

Umgangatho wamanzi ubalulekile nakwizitishi zokunyanga amanzi ezisebenzisa amanzi omlambo njengomthombo wazo. Amanqanaba aphezulu e-ammonia emanzini anokubangela iingxaki ezinkulu kwinkqubo yokubulala iintsholongwane. Ngokulinganisa ngempumelelo amanqanaba e-ammonia emanzini omlambo kwindawo yokungena yesitishi sokunyanga amanzi, umbutho uyakwazi ukukhusela unikezelo lokungena. Kwezinye izicelo, indawo yokungena ingavalwa xa amanqanaba e-ammonia efikelela kumanqanaba aphezulu ngendlela engamkelekanga.

Iindlela zangoku zokujonga i-ammonia zibiza kakhulu kwaye ziyinkimbinkimbi, zisebenzisa ii-electrode ezikhetha i-ion kunye nee-reagents ezibizayo, ziyingozi kwaye kunzima ukuziphatha. Ezi monitors nazo azicaci kwaye zifuna ukulinganiswa okuqhubekayo ukuze zilungele iimfuno ezahlukeneyo, ezinje ngonyango lwamanzi amdaka, unyango lwamanzi okusela kunye nokulinganisa amanqanaba e-ammonia emanzini omlambo. Ii-electrode ezikhetha i-ion zihlala zifuna ukulinganisa imihla ngemihla kunye nee-reagents.

I-HONDE ammonitha ye-ammonitha ithintela imingeni yee-monitha zemveli ze-ammonitha ngokusebenzisa indlela eyahlukileyo ngokupheleleyo. I-ammonitha iguqulwa ibe yi-monochloramine compound ezinzileyo kwi-concentration elingana ne-ammonia yasekuqaleni. I-concentration ye-chloramine emva koko yalinganiswa kusetyenziswa i-polaragraphic membrane sensor ene-selective linear response kwi-chloramine. I-Reaction chemistry inika i-monitha uvakalelo oluhle kakhulu nokuba kumanqanaba aphantsi kakhulu e-ammonia (ppb).

I-reagent ilula, ixabiso liphantsi kwaye isetyenziswa kancinci. Ngoko ke iindleko zobunini ziphantsi kakhulu.

Iinkampani ezinkulu zamanzi zase-UK kunye nezinye iilabhoratri ezivunyiweyo yi-Environment Agence sele zisebenzisa iimonitha ze-HONDE ukujonga ngokufanelekileyo amanqanaba e-ammonia emanzini omlambo. Le nkqubo intsha ye-ammonia evela kwi-Analytica Technologies inika abasebenzisi imonitha elula ukuyisebenzisa, engabizi kakhulu ukuyithenga, esebenza kancinci kwaye engenakuphazamiseka kokulinganisa.
