Phetoho ea Phekolo ea Metsi a Litšila: Polyamine e le Senotlolo sa Litharollo tsa Moshoelella le tse Sebetsang

Tlhoekiso ea metsi a litšila ke mokhoa oa bohlokoa oa ho netefatsa hore ho na le metsi a hloekileng le a bolokehileng bakeng sa tšebeliso ea batho le ho sireletsa tikoloho.Mekhoa e tloaelehileng ea ho hloekisa metsi a litšila e itšetlehile ka tšebeliso eali-coagulants tsa lik'hemik'hale, tse kang aluminium le matsoai a tšepe, ho tlosa litšila metsing.Leha ho le joalo, tsenaliindasteri ho hloekisa metsi lik'hemik'haleli theko e boima, li sebelisa matla a mangata, 'me li ka ba le liphello tse mpe tsa tikoloho.

Ka lehlohonolo, ho hlahile tharollo e ncha tšimong ea ho hloekisa likhoerekhoere -polyamine(PA).Polyamines ke sehlopha sa metsoako ea lintho tse phelang tseo ka tlhaho li fumanoang liseleng tse phelang 'me li na le thepa e ikhethang e etsang hore e atlehe haholo ho hloekisa metsi a litšila.Tšebeliso ea li-polyamine e fetola sebaka sa ho hloekisa metsi a litšila le ho fana ka tharollo e tsitsitseng le e sebetsang hantle bakeng sa mathata a tšilafalo ea metsi le khaello ea metsi.

China ke e 'ngoe ea bareki ba kholo ka ho fetisisa ba lik'hemik'hale tse hloekisang metsi lefatšeng, ka tlhokahalo e ntseng e hola ka potlako ea tharollo ea metsi a litšila e sebetsang hantle le e theko e tlaase.Tšebeliso ea li-polyamine indastering ea ho hloekisa metsi a litšila ea China e ntse e eketseha ka lebaka la ts'ebetso ea tsona e holimo le ho baballa ha tsona ha ho bapisoa le lik'hemik'hale tsa setso.

Li-polyamine li na le melemo e mengata ho feta lik'hemik'hale tsa khale tsa ho hloekisa metsi ka indasteri.O mong oa melemo ea mantlha ke kamano ea tsona e phahameng le litšila tse fapaneng tse fumanehang metsing a litšila, joalo ka litšepe tse boima, lidae le metsoako ea lintho tse phelang.Li-polyamine li khona ho hoama le ho thella lintho tse silafatsang tsena, e leng ho etsang hore li tlosoe habonolo metsing.Ts'ebetso ena e ntlafatsa haholo ts'ebetso e akaretsang ea ts'ebetso ea ho hloekisoa ha metsi a litšila, e bakang litšila tsa boleng bo holimo.
