Muaj ob qhov chaw ntawm Molybdenum hauv Ib puag ncig

(1) Huab cua tso tawm molybdenum los ntawm pob zeb. Nws kwv yees tias 1,000 tons ntawm nws nkag mus rau hauv dej thiab av txhua xyoo thiab tsiv mus nyob ib puag ncig. Kev faib tawm tsis sib xws ntawm molybdenum ua rau "cov kab mob hauv av thiab dej" hauv qee thaj chaw vim tsis muaj molybdenum, thiab "cov kab mob gout" (xws li Armenia) hauv qee thaj chaw vim muaj cov ntsiab lus molybdenum siab.
(ii) Kev siv dav dav ntawm molybdenum hauv tib neeg kev ua ub no thiab kev kub hnyiab ntawm molybdenum-muaj fossil fuels (xws li, thee) tau nce cov molybdenum circulating nyob rau hauv ib puag ncig. Kev tsim tawm thoob ntiaj teb ntawm molybdenum yog 100, 000 tons hauv ib xyoos, thiab 800 tons ntawm molybdenum raug hlawv thiab tso tawm rau hauv ib puag ncig txhua xyoo. Tus nqi ntawm molybdenum ntxiv rau lub voj voog los ntawm tib neeg kev ua ub no tshaj lub voj voog ntuj. Cov kev lag luam uas siv molybdenum tshaj plaws yog metallurgy, electronics, missiles thiab chaw, atomic zog, chemistry thiab kev ua liaj ua teb. Molybdenum pollution tsis tau kawm txaus.

Kev thauj ntawm molybdenum nyob rau hauv ib puag ncig yog cuam tshuam nrog oxidizing thiab txo cov xwm txheej, acidity thiab alkalinity ntawm ib puag ncig thiab kev cuam tshuam ntawm lwm yam xov xwm. Qhov ntau oxidizing thiab alkaline dej thiab av, nws yooj yim dua rau molybdenum los ua MoO ions; cov nroj tsuag tuaj yeem nqa molybdenum hauv lub xeev no. Lub acidity ntawm ib puag ncig nce los yog txo qis, molybdenum tau yooj yim hloov mus rau hauv cov ions nyuaj, thiab nws thiaj li tsim MoO; Lub xeev ntawm molybdenum no yooj yim kho los ntawm av nplaum thiab av colloids thiab humic acid thiab ua tsis muaj zog, thiab tsis tuaj yeem nqus los ntawm cov nroj tsuag. Nyob rau hauv dej hiav txwv, qhov txo qis ib puag ncig ntawm lub hiav txwv sib sib zog nqus ua rau molybdenum adsorbed los ntawm cov organic tshuaj thiab ces qhwv nyob rau hauv colloids uas muaj manganese, nws thiaj li tsim nodules uas tog rau hauv qab dej hiav txwv thiab raug tshem tawm ntawm lub voj voog ntawm lub biosphere.
Molybdenum muaj kev cuam tshuam tsawg rau cov tsiaj ntshav sov thiab ntses. Cov qib siab ntawm molybdenum muaj kev cuam tshuam tsis zoo rau cov nroj tsuag, cov kev sim qhia tau hais tias: molybdenum concentration ntawm 0.5 ~ 100 mg / liter thaum txoj kev loj hlob ntawm flax yuav muaj ntau yam kev cuam tshuam; 10 ~ 20 mg / liter thaum kev loj hlob ntawm soybeans muaj kev phom sij; 25 ~ 35 mg / liter thaum txoj kev loj hlob ntawm paj rwb yog me ntsis teeb meem; 40 mg / liter thaum loj hlob ntawm qab zib beets muaj teeb meem. Thaum lub concentration ntawm molybdenum nyob rau hauv dej nce mus txog 5 mg / l, bio-purification ntawm dej yuav inhibited; thaum 10 mg / l, cov nyhuv no yuav inhibited ntau dua, thiab cov dej muaj zog astringent saj; Thaum 100 mg / l, microbial kev loj hlob ntawm cov dej lub cev qeeb, thiab cov dej muaj iab saj. Tuam Tshoj qhia tias qhov siab tshaj plaws tso cai ntawm molybdenum nyob rau hauv dej hauv av yog 0.5 mg / l, qhov siab tshaj plaws tso cai concentration ntawm soluble molybdenum hauv chav ua haujlwm cua yog 4 mg / m3; thiab insoluble molybdenum yog 6 mg / m3.
