Leholiotsoana metsing a ka hodimo

Moferefere ke eng?
Turbidity e bolela tekanyo ea tšitiso ea tharollo ea ho feta ha leseli, e kenyeletsang ho hasana ha leseli ka lintho tse emisitsoeng le ho monya ha leseli ka limolek'hule tsa solute.
Turbidity ke parameter e hlalosang palo ea likaroloana tse emisitsoeng ka har'a mokelikeli. E amana le lintlha tse kang likahare, boholo, sebopeho, le index ea refractive ea lintho tse emisitsoeng ka metsing. Tekong ya boleng ba metsi, ho hlaka ke sesupo sa bohlokwa, se ka bonahatsang kgatello ya dintho tse tiileng tse fanyehilweng ka metsing mme hape ke o mong wa motheo wa tshekatsheko ya maikutlo ya batho ya boleng ba metsi. Hangata moferefere o lekanyetsoa ka ho metha boholo ba khanya e hasantsoeng ke ntho e itseng ka metsing ha khanya e feta sampoleng ea metsi. Hangata lintho tsena tse nyenyane li nyane, ka boholo ka kakaretso ho latela tatellano ea li-microns le ka tlase. The turbidity e bonts'itsoeng ke lisebelisoa tsa sejoale-joale hangata e hasanya moferefere, 'me yuniti ke NTU (Nephelometric Turbidity Units). Tekanyo ea turbidity ke ea bohlokoa haholo bakeng sa ho hlahloba boleng ba metsi a nooang, hobane ha e amane feela le ho hlaka ha metsi, empa hape e bonahatsa ka mokhoa o sa tobang boemo ba mahloriso a likokoana-hloko ka metsing, e amang phello ea ho thibela likokoana-hloko.
Turbidity ke tekanyo e lekantsoeng ke hore na khanya e kae e ka feta sampoleng ea metsi. Ha turbidity e phahame, leseli le fokolang le tla feta ka sampuli mme metsi a tla hlaha "cloudier". Maemo a phahameng a moferefere a bakoa ke likaroloana tse tiileng tse leketlileng ka metsing, tse hasang leseli ho e-na le ho le fetisetsa ka metsing. Thepa ea 'mele ea likaroloana tse emisitsoeng e ka ama turbidity e felletseng. Likaroloana tse kholoanyane li hasanya leseli ebe li le lebisa pele, kahoo li eketsa moferefere ka ho kena-kenana le phetiso ea leseli ka metsing. Boholo ba likaroloana bo boetse bo ama boleng ba leseli; likaroloana tse kholoanyane li hasanya makhubu a malelele a khanya habonolo ho feta maqhubu a makhutšoane, ha likaroloana tse nyenyane li na le phello e kholo ea ho hasana ha maqhubu a makhutšoane. Ho eketseha ha likaroloana ho boetse ho fokotsa phetisetso ea leseli ha leseli le kopana le palo e ntseng e eketseha ea likaroloana 'me le tsamaea sebaka se sekhutšoanyane pakeng tsa likaroloana, ho fella ka ho hasana ka makhetlo a mangata ka karoloana.

Molao-motheo oa ho lemoha
Mokhoa oa ho hasanya oa Turbidity 90-degree ke mokhoa o sebelisoang hangata ho lekanya moferefere oa tharollo. Mokhoa ona o ipapisitse le ts'ebetso ea ho hasana e hlalositsoeng ke equation ea Lorentz-Boltzmann. Mokhoa ona o sebelisa photometer kapa photometer ho lekanya matla a leseli le fetang sampole tlas'a teko le matla a khanya a hasantsoeng ke sampuli ka tsela ea ho hasana ea 90-degree, le ho lekanya ho senyeha ha sampuli ho latela litekanyetso tse lekantsoeng. Khopolo ea ho hasana e sebelisitsoeng mokhoeng ona ke: Molao oa Beer-Lambert. Khopolo ena e bolela hore tlas'a ts'ebetso ea leqhubu la sefofane se ts'oanang, karabo ea electro-optical ka har'a bolelele ba yuniti e fokotseha ka ts'ebetso ea exponential ea bolelele ba tsela ea optical, e leng molao oa khale oa Beer-Lambert. Ka mantsoe a mang, mahlaseli a khanyang a otlang likaroloana tse emisitsoeng tharollong a hasana ka makhetlo a mangata, 'me mahlaseli a mang a hasane ka li-angles tsa 90-degree. Ha u sebelisa mokhoa ona, sesebelisoa se tla lekanya karo-karolelano ea matla a leseli a hasaneng ke likaroloana tsena ka lehlakoreng la 90-degree ho ea ho matla a khanya e fetang sampuli ntle le ho hasana. Ha mahloriso a likaroloana tsa turbidity a ntse a eketseha, matla a leseli le hasaneng le ona a tla eketseha, 'me karo-karolelano e tla ba kholoanyane, ka hona, boholo ba karolelano bo lekana le palo ea likaroloana tse emisitsoeng.
Ha e le hantle, ha ho lekanya, mohloli oa leseli o hlahisoa ka ho toba ka har'a sampuli 'me sampuli e behoa sebakeng se nang le angle ea ho hasanya ea 90 °. Boleng ba turbidity ba sampole bo ka fumanoa ka ho metha matla a khanya a lekantsoeng ka kotloloho ntle le ho feta sampole le matla a khanya a 90 ° a hlahisitsoeng sampole ka fotometer, 'me a kopantsoe le mokhoa oa ho bala oa colorimetric.
Mokhoa ona o na le ho nepahala ho phahameng 'me o sebelisoa haholo ho lekanya moferefere metsing, metsi a litšila, lijo, meriana le masimo a tikoloho.

Sesosa se seholo sa metsi a ka holim'a metsi ke sefe?
