Hauv chemistry, tus neeg sawv cev sequestering yog cov organic compound muaj peev xwm txuas cov hlau ions lossis cov molecules ua ke los tsim cov nplhaib zoo li cov qauv hu ua chelates. Txawm hais tias zoo sib xws, tus neeg sawv cev sequestering txawv dua li tus neeg sawv cev chelate.
Tus piv txwv ntawm tus neeg thov sequestering yog dab tsi?
Cov neeg thov kev thov suav nrog chelants thiab qhov pib inhibitors. Chelants xws li Ethylenediaminetetraacetic Acid (EDTA), NTA, thiab DTPA react stoichiometrically (ntawm qhov sib npaug mole) nrog ions. Raws li qhov hnyav molecular ntawm EDTA yog 292 thiab calcium sulfate yog 136, yuav tsum tau siv ntau ntawm EDTA.
Yuav siv tus neeg sawv cev sequestering yog dab tsi?
Cov neeg thov kev thov raug ua haujlwm nyob rau hauv ntau daim ntawv thov xws li cov neeg tsimhauv kev tsim cov tshuaj ntxuav tes kom tshem tawm cov teebmeem cuam tshuam los ntawm cov ntsev yaj hauv cov ntsev, tshwj xeeb yog calcium lossis magnesium ntsev.
Dab tsi yog qhov txawv ntawm tus neeg sawv cev sequestering thiab tus neeg sawv cev chelate?
Sequestering agents yog cov tshuaj sib xyaw uas siv tau rau kev tshem tawm cov dej tawv. Qhov sib txawv tseem ceeb ntawm tus neeg saib xyuas chelating thiab tus neeg saib xyuas sequestering yogtus neeg sawv cev chelating tuaj yeem khi nrog ib qho hlau ion ib zaug thaum tus neeg sawv cev sequestering tuaj yeem khi nrog ob peb hlau ions ib zaug.
Puas EDTA Act sequestering agent?
Hauv kev lag luam, EDTA feem ntau yog siv los txhawm rau cov hlau ions hauv cov tshuaj aqueous . … Nyob rau hauv lub pulp thiabntawv kev lag luam, EDTA inhibits lub peev xwm ntawm hlau ions, tshwj xeeb tshaj yog Mn2+, los ntawm catalysing lub disproportionation ntawm hydrogen peroxide, uas yog siv nyob rau hauv chlorine- dawb tshuaj dawb.

Puas yog cov neeg thov kev thov ib lo lus?
the kev xav tau lossis xav tau qee yam. Lub ntsiab lus ntawm Cov Neeg Siv Khoom yog dab tsi? : ib qho uas ua lossis kos npe rau daim ntawv thov. Tus thov yog dab tsi? : ib tug uas thov: ib tug uas nug ib yam dab tsi ntawm lwm tus Tab sis nyob rau hauv lub xeev Washington, ua ntaub ntawv thov pej xeem tuaj yeem ua rau tus neeg thov raug cai raug cai raug npe nyob rau hauv ib lub xeev.
Naics 72 tus neeg thov yog leej twg?
72 - Kev Pabcuam thiab Khoom NojTsis suav nrog cov haujlwm no yog cov koom haum pej xeem thiab zej zog; chaw ua si thiab chaw ua si; ua yeeb yam; thiab lwm qhov chaw ua si lossis kev lom zem muab kev pabcuam zaub mov thiab dej haus. NAICS 72 yog dab tsi?
Tus neeg thov puas tuaj yeem thim qhov kev thov?
leej twg ua qhov kev thov tuaj yeem thim rov qab yog tias nws tseem tsis tau lees paub. Qhov no txhais tau hais tias yog tias koj ua qhov kev thov thiab lwm tus neeg xav tau qee lub sijhawm los xav txog, lossis ua kom muaj kev cuam tshuam nrog cov nqe lus hloov pauv, koj tuaj yeem thim koj qhov kev thov qub.
Leej twg yog tus neeg cog lus thiab tus neeg cog lus?
Cov neeg cog lus yog lav kev muab cov khoom tsim nyog, khoom siv, kev ua haujlwm, thiab kev pabcuam kom ua tiav koj qhov project. Lawv ntiav cov neeg ua haujlwm tshwj xeeb los ua ib feem lossis tag nrho cov haujlwm. Cov neeg cog lus siv Subcontractor Agreements los tiv thaiv lawv tus kheej thiab cov neeg ua haujlwm subcontractors lawv ntiav.
Leej twg yog neon hauv tus neeg yos hav zoov x tus neeg yos hav zoov?
Neon Nostrade (ネオン＝ノストラード) Neon muaj lub peev xwm los yav tom ntej, uas nws hu ua "Tus Ntsuj Plig Zoo Nkauj". Thaum nws tus kheej tsis paub qhov no, nws yog ib daim ntawv ntawm kev tshwj xeeb nen. Nws cov lus faj lem yog 100% tseeb thiab sau ua paj huam.
