Qhov sib txawv tseem ceeb ntawm humic acid fulvic acid thiab humin yog humic acid yog qhov dej-insoluble ntawm cov av uas tuaj yeem yaj ntawm tus nqi pH sib txawv, thiab fulvic acid yog cov dej-soluble ntawm cov av, whereas humin yog insoluble nyob rau hauv dej ntawm tej pH.
Humic acid yog cov khoom tseem ceeb ntawm cov tshuaj humic, thiab nws yog cov organic compound. Fulvic acid yog ib hom organic acid uas tshwm sim ua ib feem ntawm humus. Humin yog cov khoom siv carbon-based macromolecular uas tshwm sim hauv av lossis raws li cov khoom lag luam ntawm saccharide-dependent biorefinery txheej txheem.
YHumic Acid yog dab tsi?
Humic acid yog cov khoom tseem ceeb ntawm cov tshuaj humic, thiab nws yog cov organic compound. Nws yog ib feem ntawm cov organic feem ntau ntawm cov av, peat, thiab thee. Tsis tas li ntawd, peb tuaj yeem pom nws ua ib feem ntawm ntau thaj av toj roob hauv pes ntawm cov kwj deg, cov pas dej dystrophic, thiab dej hiav txwv.
Yav dhau los, humic acid tau txhais tias yog cov organic acid uas lub hauv paus ntawm cov kua qaub no yog humate. Raws li cov ntsiab lus no, humic acid yog cov organic uas tau muab rho tawm los ntawm cov av uas tuaj yeem coagulate thaum acidification nrog lub zog-puag extract.
Daim duab 01: Ib Hom Humic Acid Structure
Thaum humic acid yog coj los ua ib qho kev cais, nws yog qhov tshwm sim ntawm cov tshuaj rho tawm los ntawm cov av organic teeb meem los yog yaj cov organic teeb meem, uas sawv cev rau humic molecules uas tau faib thoob plaws hauv av.
Fulvic Acid yog dab tsi?
Fulvic acid yog ib hom organic acid uas tshwm sim ua ib feem ntawm humus. Cov no yog natural compounds. Nws tshwm sim raws li ib feem ntawm cov av organic teeb meem. Fulvic acid zoo ib yam li humic acid tab sis muaj qhov sib txawv me ntsis hauv dej solubility thiab xim.
Peb tuaj yeem tshem tawm fulvic acid ntawm pH siab los ntawm kev kho av humus nrog kev daws ntawm NaOH. Lub dissolution ntawm fulvic acid yog nyiam los ntawm dissociation thiab ionization ntawm pawg carboxylic acid thiab phenol pawg ntawm high pH. Muaj ib feem insoluble ntawm humus uas tseem tshuav tom qab leaching los ntawm NaOH hu ua humin. Ua raws li kev rho tawm ntawm fulvic acid siv cov tshuaj alkaline, peb tuaj yeem cais nws los ntawm cov tshuaj tiv thaiv sib xyaw los ntawm kev ntxiv acidification ntawm cov kua qaub. Txawm li cas los xij, siab molecular hnyav fulvic acid tebchaw tuaj yeem nyob hauv cov tshuaj tom qab nag lossis daus ntawm qhov hnyav molecular hnyav humic acids los ntawm acidification ntawm pH=1.
Tsis tas li ntawd, fulvic acid tsim los ntawm microbial degradation ntawm cov nroj tsuag hauv av uas muaj cov pa oxygen txaus. Txawm li cas los xij, qhov sib xyaw no tsis yooj yim ua ke. Qhov no yog vim qhov nyuaj heev ntawm cov compound no.
Humin yog dab tsi?
Humin yog cov tshuaj carbon-based macromolecular uas tshwm sim hauv av lossis ua cov khoom lag luam ntawm saccharide-dependent biorefinery txheej txheem. Hauv av chemistry, peb tuaj yeem pom tias av muaj cov organic thiab inorganic compounds. Inorganic compounds feem ntau yog cov ntxhia. Peb muaj peev xwm faib cov organic Cheebtsam nyob rau hauv cov av rau hauv ob peb feem: soluble Cheebtsam, xws li humic acids, thiab insoluble Cheebtsam, nrog rau humin tshuaj. Ib feem ntawm humin hauv av yuav siv li 50% ntawm cov organic teeb meem hauv av. Humin muaj cov qauv molecular nyuaj heev. Yog li ntawd, peb nrhiav tsis tau lawv li cov tshuaj dawb huv tab sis raws li kev sib xyaw nrog lwm cov tebchaw.
Ntxiv mus, cov tshuaj humin tsim thaum lub sijhawm hloov pauv ntawm lignocellulosic biomass rau hauv me me, muaj txiaj ntsig zoo cov organic tebchaw xws li HMF. Hom tshuaj humin no ua rau cov kua lossis cov khib nyiab raws li cov txheej txheem siv.

Feem ntau, humin tsis suav tias yog cov khoom txaus ntshai. Qhov no txhais tau hais tias cov tshuaj no feem ntau tsis tawg, tawg, raug oxidation, corrosive, lossis eco-toxic. Tsis tas li ntawd, yog tias peb sov humin, nws tuaj yeem tsim macroporous hu ua humin foam. Txawm li cas los xij, cov ntaub ntawv no tsis nthuav tawm cov cwj pwm tseem ceeb ntawm hluav taws vim yog cov qauv ntxeem tau.
Qhov txawv ntawm Humic Acid Fulvic Acid thiab Humin yog dab tsi?
Humic acid yog ib qho tseem ceeb ntawm cov tshuaj humic, thiab nws yog cov organic compound. Fulvic acid yog ib hom organic acid uas tshwm sim ua ib feem ntawm humus. Humin yog cov khoom siv carbon-based macromolecular uas tshwm sim hauv cov av lossis raws li cov khoom lag luam ntawm saccharide-dependent biorefinery txheej txheem. Qhov sib txawv tseem ceeb ntawm humic acid fulvic acid thiab humin yog humic acid yog qhov dej-insoluble ntawm cov av uas tuaj yeem yaj ntawm tus nqi pH sib txawv, thiab fulvic acid yog qhov dej-soluble ntawm av, whereas humin yog insoluble hauv dej ntawm txhua pH.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm humic acid fulvic acid thiab humin hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Humic Acid vs Fulvic Acid vs Humin
Humic acid, fulvic acid, thiab humin yog cov khoom tseem ceeb hauv av. Lawv txawv ntawm cov qauv tshuaj thiab cov tsos mob feem ntau. Qhov sib txawv tseem ceeb ntawm humic acid fulvic acid thiab humin yog humic acid yog qhov dej-insoluble ntawm cov av uas tuaj yeem yaj ntawm tus nqi pH sib txawv, thiab fulvic acid yog qhov dej-soluble ntawm av, whereas humin yog insoluble hauv dej ntawm txhua pH.
