Ntshiab phosphorus yog siv los ua tshuaj rau siv hauv kev lag luam. Qhov tseem ceeb tshaj plaws siv phosphate pob zeb, txawm li cas los xij, yog nyob hauv kev tsim khoom phosphate chiv rau kev ua liaj ua teb. Yuav luag txhua cov chiv ua ke muaj qhov ntsuas "N-P-K". Phosphorus yog "P" hauv cov chiv.
Ib qho ntxiv, pom cov phosphates nyob qhov twg?
Cov neeg tsim khoom loj tshaj plaws hauv ntiaj teb thiab xa tawm ntawm phosphates yog Morocco. Hauv North America, cov nyiaj tso loj tshaj plaws nyob hauv thaj tsam Bone Valley ntawm nruab nrab Florida, thaj chaw Soda Springs ntawm sab qab teb sab hnub tuaj Idaho, thiab ntug dej hiav txwv ntawm North Carolina. Cov nyiaj me me yog nyob hauv Montana, Tennessee, Georgia, thiab South Carolina.
Kuj Paub, dab tsi yog piv txwv ntawm phosphates? Phosphate minerals suav nrog:
- Triphylite Li (Fe, Mn) PO4
- Monazite (La, Y, Nd, Sm, Gd, Ce, Th) PO4, lub ntiaj teb tsis tshua muaj hlau.
- Hinsdalite PbAl3(POJ4) (TSO4) (OH)6
- Pyromorphite Pb5(POJ4)3Cl.
- Erythrite Co.3(As OS4)2· 8H npe2O.
- Amblygonite LiAlPO4F.
- lazulite (Mg, Fe) Al2(POJ4)2(OH)2
- Wavellite AW3(POJ4)2(OH)3· 5 hli2O.
Qhov thib ob, yam khoom twg yog tsim los ntawm phosphate?
Qib siab phosphate pob zeb yog siv hauv kev tsim cov chiv thiab pub additives , thiab tseem nyob hauv kev kho mob ntawm dej thiab hlau, kev tsim cov xab npum thiab tshuaj txhuam hniav , ua ntawm nqaij khoom, cheese thiab dej qab zib hauv kev lag luam khoom noj khoom haus, nrog rau tsim cov roj teeb rau tsheb fais.
Koj txheeb xyuas phosphates li cas?
Cov txheej txheem tsim nyog Lub xub ntiag ntawm phosphate ions tau qhia los ntawm kev tsim cov xim daj daj nag lossis daus txheej ntawm ammonium phosphomolybdate. Cov tsos ntawm nag lossis daus tuaj yeem ua kom yooj yim los ntawm cua sov. Qhov kev xeem no tseem siv rau paub arsenic, cov xim daj daj tau tsim.

Qhov sib txawv ntawm kev txhawb siab rau kev ua haujlwm thiab kev ntxub ntxaug kev ntxub ntxaug yog dab tsi?
Nco ntsoov tias kev txhawb nqa kev ua haujlwm sib txawv los ntawm kev sib cais kev ntxub ntxaug (Sd). Qhov kev ntxub ntxaug qhia tias muaj kev txhawb nqa ntxiv, thaum lub zog txhawb nqa kev hloov pauv kev ua haujlwm ntawm tus txhawb nqa
Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Kev tsis saib xyuas yog dab tsi thiab plaub theem hauv kev ua pov thawj qhov tsis saib xyuas yog dab tsi?
Kev tsis lees paub yuav tsum ua pov thawj plaub yam hauv tsev hais plaub: lub luag haujlwm, ua txhaum cai, ua rau raug mob, thiab puas tsuaj/raug mob. Feem ntau hais lus, thaum ib tus neeg ua qhov tsis saib xyuas thiab ua rau raug mob rau lwm tus neeg, raws li txoj cai lij choj ntawm 'kev tsis saib xyuas' tus neeg tsis saib xyuas yuav raug cai raws txoj cai rau qhov ua rau raug mob
Dab tsi yog phosphate mining siv rau?
Thoob ntiaj teb, ntau dua 85 feem pua ntawm cov pob zeb phosphate tau siv los tsim cov chiv chiv. Qhov seem 15 feem pua yog siv los ua cov tshuaj phosphorus thiab tsiaj pub, lossis siv ncaj qha rau cov av. Elemental phosphorus yog siv los tsim ntau hom tshuaj sib txuas
Puas yog dicalcium phosphate zoo ib yam li calcium phosphate?
Dicalcium phosphate yog calcium phosphate nrog cov mis CaHPO4 thiab nws cov dihydrate. Qhov 'di' ua ntej hauv lub npe tshwm sim vim tias kev tsim ntawm HPO42– anion cuam tshuam nrog kev tshem tawm ob lub protons los ntawm phosphoric acid, H3PO4. Nws tseem hu ua dibasic calcium phosphate los yog calcium monohydrogen phosphate
