Humic Acid Kho Cov Av

Kev kho av yog hais txog kev siv lub cev, tshuaj lom neeg thiab txheeb raws roj ntsha mus hloov, nqus, hloov thiab hloov cov kab mob hauv cov av, txo nws qhov kev xav kom haum, los yog hloov cov kab mob lom thiab tsim kev puas tsuaj rau cov khoom tsis huv. Nyob rau hauv kev lag luam kev kho av, cov cuab yeej siv kho av uas twb muaj lawm rau ntau tshaj 100 hom kev siv technology lawm muaj ntau tshaj 10 yam, yuav muab faib rau kev siv lub cev, tshuaj lom neeg thiab lom neeg peb.

Raws li, cov txheej txheem kev tswj hwm cov kab mob paug tau muaj xws li:

(1) hloov paug cov kab mob hauv cov av los yog kev sib xyaw nrog cov av, txo nws cov tsiv mus nyob rau ib puag ncig thiab bioavailability;

(2) txo cov concentration ntawm teeb meem tshuaj hauv cov av.

Nyob rau hauv tus txheej txheem ntawm av pa phem tswj, av kev txhim kho, humic acid qhia tau hais tias ib tug zoo dua thiab zoo dua cov nyhuv.

Vim li cas cov kua qaub?

Humic acid yog ib hom tshuaj macromolecule organic uas pom muaj nyob hauv cov xwm txheej.

Humic acid yog ib tsob nroj thiab tsiaj tshua, feem ntau qhov seem ntawm cov nroj tsuag, los ntawm kev siv zug thiab kev hloov ntawm cov kab mob, nrog rau cov txheej txheem geochemical tshwm sim tuaj thiab tsim tau ib chav kawm ntawm cov organic teeb meem. Qee qhov kev xyaw hauv kev lag luam niaj hnub no kuj tuaj yeem ua humic acid.

Humic acid raw khoom tau muab faib ua ob pawg: coal thiab non-coal tshuaj.

Lub qub yog xws li peat, lignite thiab weathered thee; ntawm lawv, humic acid cov ntsiab lus ntawm 10-80%.

Tuam Tshoj tus peev reserves yog nplua nuj, raws li cov ntaub ntawv, muaj 5 billion tons ntawm peat, lignite 126.5 lab tons, weathered thee yog tseem tsis muaj ntaub ntawv tawm.

Cov tom kawg no muaj av, dej, fungi thiab lwm yam khoom uas tsis yog thee, xws li phenols, quinones, carbohydrates thiab lwm yam tshuaj, lawv yog bio-fermentation, oxidation lossis synthesis tuaj yeem ua humic tshuaj, xws li lub khw tam sim no, .

Humic acid yog ib qho tseem ceeb ntawm humus, cov qauv tshuaj yog complex, yog muaj cov carboxyl, phenol, ketone, phenolic hydroxyl thiab lwm yam kev ua haujlwm ntawm cov tshuaj sib tov, humic acid tshwj xeeb qauv thiab lub cev thiab tshuaj cov khoom ntawm nws cov kev txiav txim siab hauv kev kho kom zoo Rau lub luag haujlwm tseem ceeb.

Yuav ua li cas humic acid fixes av

Humic acid nyob rau hauv "hnyav hlau thiab cov tshuaj lom muaj kuab paug" cov kab mob paug thaj av muaj xws li: humic acid on heavy metals thiab cov organic teeb meem adsorption nag lossis daus; redox; thiab humic acid tuaj yeem ua rau cov kab mob av cov kab mob ntawm cov pa phem degradation.
