Kev cuam tshuam ib puag ncig thiab tshuaj lom neeg ntawm sodium hydrosulfide
Sodium Hydrosulfide, (Nahs) yog qhov sib txuas ua ke uas yog lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam ntawm cov sodium thiolate thiab lwm yam sodium hydrosulfides. Txawm hais tias nws siv tau nyob rau hauv kev lag luam xws li mining, kev kho kom zoo ntawm sodium hydrosulfide thiab nws cov kev tawm tsam tsis tuaj yeem tsis quav ntsej.
Sodium Hydrosulfide yog tus neeg sawv cev muaj zog, uas txhais tau tias nws tuaj yeem koom nrog kev sib txuas ntawm Sulfide cov tebchaw. Thaum sodium hydrosulfide tawm mus rau ib puag ncig, nws ua kom muaj hlau ua los ua insoluble hlau sulfides uas precipitive tawm ntawm kev daws teeb meem. Cov cuab yeej no feem ntau siv nyob rau hauv kev kho kom tshem tawm cov tshuaj lom neeg muaj kuab lom, tab sis nws tseem tau tsa kev txhawj xeeb txog kev sib kis ib puag ncig yog tias tsis tswj kom zoo.
Qhov cuam tshuam ib puag ncig ntawm sodium hydrosulfide ilegate yog multifaceted. Ntawm ib sab tes, nws lub peev xwm los detoxify cov hlau hnyav yog qhov txiaj ntsig zoo rau kev muaj cov txheej txheem. Ntawm qhov tod tes, tuav tsis raug cai lossis kev tso tawm tsis raug mob tuaj yeem ua rau muaj kev puas tsuaj ecological. Qhov no muaj tshuaj sib txuas lus rau dej rog, thiab nws muaj nyob hauv dej lub cev tuaj yeem ua kev puas tsuaj rau cov ecosystem. Tsis tas li ntawd, cov roj hlawv roj hydrogen sulfide thaum cov tshuaj tiv thaiv tuaj yeem ua rau muaj kev hem thawj rau cov neeg noj qab haus huv thiab tsiaj qus.
Hauv cov ntsiab lus xaus, thaumSodium Hydrosulfide HydrateThiab nws cov derivatives, xws li sodium thiole, muaj txiaj ntsig zoo nyob rau ntau yam kev siv khoom, lawv qhov cuam tshuam ib puag ncig yuav tsum tau txiav txim siab. Kev Tswj Xyuas lub luag haujlwm thiab kev ua raws li kev nyab xeeb cov kev cai yog qhov tseem ceeb rau kev txo qis ntawm kev siv lawv. Kev lag luam txuas ntxiv rau cov tshuaj no, txuas ntxiv kev tshawb fawb thiab cov kev cai yog qhov tseem ceeb kom paub meej tias lawv cov txiaj ntsig tsis tau los ntawm kev siv nyiaj ib puag ncig.
