Humic Acid Txoj Kev Cia Siab

Xi'an Naturetech Co., Ltd | Updated: Sep 25, 2017

Humic acid yog siv cov khoom siv rau hauv cov av, dav siv hauv kev ua liaj ua teb, hav zoov, tsiaj husbandry, roj av, tshuaj lom neeg kev lag luam, khoom tsim, tshuaj, kev noj qab haus huv, kev tiv thaiv ib puag ncig thiab lwm yam kev lag luam. Tshwj xeeb yog tam sim no, cov qib ntawm kev ua liaj ua teb kev ua liaj ua teb, kev ua qoob loo-dawb ua liaj ua teb qhuav, cov zaub mov ntsuab, cov pa phem tsis pub ib puag ncig thiab lwm yam, ua "humic acid" heev qhuas. Nws hloov tawm tias tib neeg lub neej tsis tuaj yeem nyob tsis muaj humic acid.

Humic acid yog qhov tseem ntawm cov nroj tsuag thiab tsiaj txhu, feem ntau qhov seem ntawm cov nroj tsuag, los ntawm kev siv zug thiab kev hloov ntawm cov kab mob, thiab cov txuam nrog ib chav ntawm cov organic khoom los ntawm cov txheej txheem ntawm cov txheej txheem geochemical. Nws yog ib qho nyiaj staggering, billions ntawm tons. Dej thiab pas dej, av av, feem ntau ntawm qhov chaw muaj nws qhov cim tseg. Vim tias nws txoj kev ua neej nyob hauv ntiaj teb no kuj zoo kawg thiab, uas yog cov voj voog, cov pob zeb tawg paj txig, cov av fertility, qhov kev lag luam thiab lwm yam. Tus nqi ntawm humic acid hauv av yog qhov loj, tab sis cov ntsiab lus yog tsawg tshaj li 1% ntawm nruab nrab, thiab tus nqi ntawm cov ntsev dej tsis tsawg, tab sis qhov concentration yog qis. Cov qoob loo kua qaub (humic acid) uas zoo tshaj plaws yuav tsum tau siv yog cov uas tsis muaj calorific thee, xws li peat, lignite thiab weathering coal. Ntawm lawv, humic acid cov ntsiab lus nce mus txog 10-80%. Tuam Tshoj lub peev reserves yog nplua nuj heev. Raws li cov ntaub ntawv, muaj 5 billion tons ntawm peat, 126.5 lab tons of lignite thiab tsis muaj statistics ntawm weathering thee. Nyob rau hauv qhov kev nkag siab, ntau lawm thiab daim ntawv thov ntawm humic acid kuj yog ib qho ntawm cov kev lag luam hauv kev lag luam chemical. Tus qauv ntawm humic acid macromolecules yog lub nplhaib uas muaj suab nrov thiab lipid nplhaib, uas muaj cov kev ua haujlwm ntawm carboxyl, hydroxyl, carbonyl, quinone thiab methoxyl.

Ciaj sia taus txheej xwm quo

Lub thawv yog tsim los ntawm cov khoom lom ntawm kev tuag, xws li lignin, uas tau degraded los ntawm microbial degradation thiab tsis tau ntxiv degraded. Nws cov kev ua tau zoo thiab cov qauv yog nyob ntawm seb cov kev cai ntawm ib yam qauv ntawm cov dej los sis cov av. Txawm li cas los xij, txawm tias qhov chaw ntawm humus txawv, qhov kev ua tau zoo heev. Humic acid yuav muab faib ua peb qhov tseem ceeb hauv av thiab thooj: Humic acid (HA), fulvic acid (FA) thiab humin (HM). HA yog soluble nyob rau hauv lub hauv paus, tab sis insoluble hauv dej thiab kua qaub; FA yog ob qho tib si soluble nyob rau hauv alkali thiab soluble nyob rau hauv dej thiab acid; Thiab HM yog nyob rau hauv cov dej tsis zoo, ua tsis taus pa hauv dej thiab kua qaub. Lub peev xwm los disjoin cov hlau ions hauv cov dej kom pab tau cov kev hloov ntawm cov as-ham cov ntsiab lus rau cov qoob loo thiab los txhim kho cov av cov av yog qhov ua rau txoj kev loj hlob ntawm cov qoob loo. Nws muaj qhov kev hloov ntawm kev sib pauv, adsorption, kev sib txuas thiab chelation ntawm hlau ions; Raws li ib tug polyelectrolyte nyob rau hauv lub dispersive system, nws muaj cov kev ua ntawm coagulation, gelation thiab dispersion. Humic acid molecules muaj ib cov xov tooj ntawm cov dawb radicals, uas muaj cov kev ua muaj sia.

Ntau txoj kev

Nws tuaj yeem tsim cov kua qia hluav nchuav los ntawm khoom cua oxidation (xws li cua, ozone lossis nitric acid kho), xws li nitric humic acid. Txoj kev extraction yog kho cov kua qaub ua ntej, tshem qee cov minerals tawm, thiab ces muab cov dilute dilution alkali thiab acid acidification, thiab tom qab ntawd ces nag kua txob tuaj yeem muab tau. Raws li lub solubility ntawm humic acid nyob rau hauv cov kuab tshuaj, nws muaj peev xwm raug muab faib ua peb qho: lub soluble nyob rau hauv acetone los yog ethanol hu ua xim av saproic acid; Qhov txheej txheem ntawm acetone insoluble yog hu ua dub saproic acid; Tshooj uas yog nyob hauv dej los yog dilute acid hu ua yellowish acid. Tus qauv ntawm humic acid macromolecules yog lub nplhaib uas muaj suab nrov thiab lipid nplhaib, uas muaj cov kev ua haujlwm ntawm carboxyl, hydroxyl, carbonyl, quinone thiab methoxyl. Nws muaj qhov kev hloov ntawm kev sib pauv, adsorption, kev sib txuas thiab chelation ntawm hlau ions; Raws li ib tug polyelectrolyte nyob rau hauv lub dispersive system, nws muaj cov kev ua ntawm coagulation, gelation thiab dispersion. Humic acid molecules muaj ib cov xov tooj ntawm cov dawb radicals, uas muaj cov kev ua muaj sia.

Txoj kev khaws cia

Siv lub pob zeb qhuav, qhuav 200kg galvanized hlau nruas pob. Cov khoom no yog ntub thiab muaj zog. Nws yuav tsum tau ceev cia rau hauv qhov chaw qhuav thiab qhov chaw tso cua. Nws yog txwv tsis pub mus pom dej. Cov txheej txheem kev thauj khoom yuav tsum tsis txhob muaj kev sib tsoo kev sib tsoo thaum raug tawg. Lub sij hawm cia lub sij hawm cia yog ib xyoos.
