Dab tsi yogLanthhanum (III) Chloridesiv rau?
Ib daim ntawv thov ntawm Lanthhanum chloride yog qhov kev tshem tawm ntawm phosphate los ntawm cov kev daws teeb meem los ntawm kev ua luam dej kom tiv thaiv cov khoom ua luam dej thiab lwm yam dej khib nyiab. Nws yog siv rau kev kho mob hauv cov thoob dej yug ntses, cov dej hauv chaw nyob nrog hauv cov chaw muaj dej rau kev tiv thaiv algae kev loj hlob.
Lanthhanum chloride (Lacl3) kuj tau ua kom pom kev siv cov kev pab lim thiab cov flocculent zoo. Lanthhanum chloride tseem siv nyob rau hauv kev tshawb fawb biochemical los thaiv kev ua si ntawm cov kev sib tham sib xyaw ua ke, feem ntau calcium raws. Doped nrog cerium, nws yog siv los ua cov khoom siv scintillator.
Nyob rau hauv cov synthic synthesis, Lanthhanum trichhloride muaj nuj nqi ua ib tug me lewis acid rau kev hloov aldehydes rau acetals.
Cov compound tau txheeb xyuas raws li kev ua yeeb yam rau lub siab siab oxidatinatine chloromethane nrog hydrochloric acid thiab oxygen.
Lanthhanum yog lub ntiaj teb tsis tshua muaj hlau uas muaj txiaj ntsig zoo ntawm kev tsim tsa phosphate hauv dej. Nyob rau hauv daim ntawv ntawm lanthhanum chloride ib qho koob tshuaj me me qhia rau phosphate laden dej tam sim ntawd ua tau siv cov khoom siv xuab zeb lim.
Lacl3 tshwj xeeb tshaj yog ua tau zoo tshaj plaws hauv kev txo cov tshuaj siab phosphate siab heev.
