Yog dab tsiLanthanum (III) chloridesiv rau?
Ib qho kev siv lanthanum chloride yog kev tshem tawm cov phosphate ntawm cov tshuaj los ntawm kev nag lossis daus, piv txwv li hauv cov pas dej ua luam dej kom tiv thaiv kev loj hlob ntawm algae thiab lwm yam kev kho dej khib nyiab. Nws yog siv rau kev kho mob hauv cov thoob dej yug ntses, cov chaw ua si dej, cov dej nyob hauv tsev thiab hauv cov chaw nyob hauv dej kom tiv thaiv kev loj hlob ntawm algae.
Lanthanum Chloride (LaCl3) kuj tau pom tias siv tau ua ib qho kev pab lim dej thiab ib qho flocculent zoo. Lanthanum chloride kuj tseem siv rau hauv kev tshawb fawb biochemical los thaiv cov haujlwm ntawm divalent cation channels, feem ntau yog calcium channels. Doped nrog cerium, nws yog siv ua scintillator khoom siv.
Hauv cov organic synthesis, lanthanum trichloride ua haujlwm ua ib qho Lewis acid me me rau kev hloov cov aldehydes rau acetals.
Cov tshuaj no tau raug txheeb xyuas tias yog ib qho catalyst rau kev ua kom muaj kev kub siab oxidative chlorination ntawm methane rau chloromethane nrog hydrochloric acid thiab oxygen.
Lanthanum yog ib hom hlau uas tsis tshua muaj nyob hauv ntiaj teb uas zoo heev rau kev tiv thaiv kev sib sau ua ke ntawm phosphate hauv dej. Hauv daim ntawv ntawm Lanthanum Chloride, ib qho me me ntawm cov tshuaj uas tau muab rau hauv dej uas muaj phosphate tam sim ntawd tsim cov flocs me me ntawm LaPO4 precipitate uas tom qab ntawd tuaj yeem lim tau siv cov lim xuab zeb.
LaCl3 muaj txiaj ntsig zoo rau kev txo cov phosphate ntau heev.
