Qhov sib txawv tseem ceeb ntawm orthophosphate thiab polyphosphate yog orthophosphate tsuas muaj ib chav phosphate xwb, hos polyphosphate muaj ob peb phosphate units.
Orthophosphate thiab polyphosphate yog inorganic ntsev compounds. Peb tuaj yeem paub qhov txawv ntawm ob lub tebchaw los ntawm lawv cov qauv tshuaj: nyob ntawm seb muaj pes tsawg tus phosphate units hauv cov qauv tshuaj.
Orthophosphate yog dab tsi?
Lub sij hawm orthophosphate tuaj yeem txhais tau tias yog ntsev lossis ester ntawm orthophosphoric acid. Thaum H + ions poob los ntawm orthophosphoric acid, ib qho orthophosphate anion yog tsim. Cov tshuaj formula ntawm orthophosphate anion yog –PO4-3, thiab nws molar mass yog 94.97 g/mol.
Daim duab 01: Pom ntawm Phosphate Unit
Peb feem ntau hu cov anion no ua phosphate anion vim orthophosphate yog qhov yooj yim ntawm cov tswv cuab ntawm phosphate series. Ntxiv mus, peb tuaj yeem hu nws monophosphate vim nws muaj ib chav phosphate. Lwm cov tswv cuab ntawm phosphate series muaj ob lossis ntau dua phosphate units.
Thaum xav txog cov ntawv thov ntawm orthophosphate, nws yog ib qho kev tiv thaiv corrosion uas muaj txiaj ntsig zoo rau cov neeg siv dej txhawm rau txhawm rau tiv thaiv cov kav dej los ntawm leaching.
YPolyphosphate yog dab tsi?
Lub sij hawm polyphosphate yog siv rau ntsev los yog esters ntawm polymeric oxyanions uas yog tsim los ntawm tetrahedral phosphate structural units. Cov qauv qauv no tau txuas ua ke los ntawm kev sib koom cov pa oxygen atoms. Feem ntau, cov ntsev sib xyaw no zoo li yuav siv cov kab los yog lub voj voog voj voog.
Daim duab 02: Cov qauv tshuaj ntawm Polyphosphoric Acid
Ob hom polyphosphate compounds suav nrog ADP thiab ATP. Cov tebchaw no tseem ceeb hauv kev khaws cia lub zog. Muaj ntau yam sib txawv polyphosphates uas muaj cov ntawv thov sib txawv hauv cov ntxhia sequestration hauv cov dej hauv nroog. Ntxiv mus, polyphosphates muaj txiaj ntsig zoo hauv kev lag luam khoom noj khoom haus raws li cov khoom noj khoom haus hauv qab E tus lej E452.
Thaum xav txog kev tsim thiab kev sib txuas ntawm cov ntsev polyphosphate, peb tuaj yeem tsim lawv los ntawm polymerization ntawm phosphoric acid derivatives. Feem ntau, qhov polymerization no pib nrog ob chav phosphate uas tuaj ua ke hauv cov tshuaj tiv thaiv condensation. Cov tshuaj tiv thaiv condensation no feem ntau yog qhov sib npaug.
Ntxiv mus, cov tshuaj polyphosphate yog cov hauv paus tsis muaj zog. Muaj ib tug ib leeg electron khub ntawm ib tug oxygen atom. Ob leeg electron no tuaj yeem pub dawb rau hydrogen ion lossis hlau ion los ntawm Lewis acid-Lewis puag cuam tshuam.
Qhov txawv ntawm Orthophosphate thiab Polyphosphate yog dab tsi?
Lub sij hawm orthophosphate tuaj yeem txhais tau tias yog ntsev lossis ester ntawm orthophosphoric acid thaum lub sij hawm polyphosphate yog siv rau cov ntsev los yog esters ntawm polymeric oxyanions uas yog tsim los ntawm tetrahedral phosphate structural units. Peb tuaj yeem paub qhov txawv ntawm orthophosphate tebchaw los ntawm polyphosphate tebchaw los ntawm lawv cov qauv tshuaj. Qhov sib txawv tseem ceeb ntawm orthophosphate thiab polyphosphate yog orthophosphate tsuas muaj ib chav phosphate xwb, hos polyphosphate muaj ob peb phosphate units.
Feem ntau, orthophosphates yog cov molecules me me vim tias muaj ib chav phosphate ib molecule. Tab sis polyphosphates yog cov molecules loj dua orthophosphates vim tias muaj ntau tshaj li ib chav tsev phosphate ib molecule. Tsis tas li ntawd, orthophosphate yog cov tshuaj tiv thaiv corrosion uas siv los ntawm cov neeg siv dej los tiv thaiv cov kav dej los ntawm leaching, whereas polyphosphate muaj ntau yam kev siv, nrog rau nws lub luag hauj lwm raws li ib tug thickening neeg sawv cev nyob rau hauv kev lag luam khoom noj khoom haus, siv nyob rau hauv dej kho tshuab, thiab lwm yam.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm orthophosphate thiab polyphosphate hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Orthophosphate vs Polyphosphate
Orthophosphate thiab polyphosphate yog inorganic ntsev compounds. Peb tuaj yeem paub qhov txawv ntawm ob lub tebchaw los ntawm lawv cov qauv tshuaj, nyob ntawm seb muaj pes tsawg tus phosphate units hauv cov qauv tshuaj. Qhov sib txawv tseem ceeb ntawm orthophosphate thiab polyphosphate yog tias orthophosphate tsuas muaj ib chav phosphate xwb, hos polyphosphate muaj ob peb phosphate units.
