Error. -----------【The mechanism is based on the fact that H2S and CO2, which are soluble in water, have slight acidity; they react with amines (which are weakly basic) to form salts that decompose at high temperatures.】 The amine solution used for desulfurization contains at least one hydroxyl group and one amino group; the hydroxyl group serves to reduce the vapor pressure and increase water solubility, while the amino group helps to achieve the necessary alkalinity in the aqueous solution, thereby facilitating the absorption of acidic gases. 】
Is there something wrong with the OP’s title? A solution is composed of a solvent and a solute. Generally, when we talk about the concentration of a solution, we are referring to the concentration of the solute. Do we often mention the concentration of the solvent? Solvents can be mixed, but not in terms of exact concentration values; rather, it is expressed as a simple volume or weight ratio. Only the concentration of the solute is intentionally expressed as a specific value.
