少量KOH与CO2反应：CO2 + KOH → KHCO3；离子方程式为：CO2 + OH- → HCO3-。过量KOH与CO2反应：CO2 + 2KOH → K2CO3 + H2O；离子方程式为：CO2 + 2OH- → CO3^2- + H2O。解释：少量的氢氧化钾与二氧化碳反应时，二者主要形成碳酸钾和水。具体反应中，氢氧化钾的氢...
Alternatively, CO2 storage solutions based on KOH and K2CO3 have been considered [22]. Aqueous solutions of amino acids and ionic liquids have been inves- tigated [28,29]. Compared with amine-based technology, amino acid-based technology has the advantages of low toxicity, high biodegradation ...
