Qhov no yog daim ntawv qhia pab dej hiav txwv kom nqus tau ntau ntawm peb cov pa roj carbon dioxide: ntxiv limestone. Nws tuaj yeem tsis tsuas yog pab txo kom sov lub ntiaj teb tab sis kuj tseem tuaj yeem txhawb nqa cov kab mob coral reefs. Thaum atmospheric CO2 dissolves nyob rau hauv dej hiav txwv, nws reacts nrog carbonate ions nyob rau hauv cov dej saum npoo los tsim bicarbonate ions.

Puas yog limestone nqus cov pa roj carbon dioxide?

Lub voj voog txiv qaub pib thaum limestone raug hlawv thiab tso CO2 rau hauv qhov chaw. Cov txheej txheem slaking nws thiaj li tsim calcium di-hydroxide, uas yog muag raws li ib lub hnab ntim txiv qaub hmoov. … Raws li lub mortar hardens, nws reabsorbs cov pa roj carbon dioxide nyob rau hauv cov huab cua thiab nws thiaj li re-hardens rau limestone.

Limestone cuam tshuam CO2 li cas?

Cov limestone tseem tuaj yeem yaj mus rau hauv calcium bicarbonate nrog rau cov pa roj carbonic acid (H2CO3) uas tsim thaum cov av noo noo uptakes atmospheric CO2 emissions, raws li qhia nyob rau hauv tshuaj tiv thaiv (2). Cov bicarbonate tuaj yeem nkag mus rau hauv av thiab thauj los ntawm cov dej ntws mus rau dej hiav txwv.

Lub pob zeb twg absorbs carbon dioxide?

Tshwj xeeb, txoj kev tshawb fawb pom tias ntxiv crushed silicate pob zeb zoo li bas alt -cov seem ntawm cov hluav taws kub thaum ub-tuaj yeem ua raws li cov pa roj carbon monoxide. Thaum cov pob zeb zoo li no yaj hauv cov av, carbon dioxide absorbed thiab cov as-ham tseem ceeb raug tso tawm rau cov nroj tsuag.

carbon dioxide absorbed los ntawm dab tsi?

Thaum cov pa roj carbon dioxide CO2 tawm mus rau hauv qhov chaw los ntawm kev hlawv cov pob txha, kwv yees li 50% tseem nyob hauv qhov chaw, thaum 25% yog nqus los ntawm land nroj tsuag thiab ntoo, thiab lwm yam 25% yog nqus mus rau qee qhov chaw ntawm dej hiav txwv.
