Carbon dioxide increase in the atmosphere is a relentless rise process. Many mitigation measures aimed at the reduction of carbon dioxide emissions coupled with capture in variously stable sequestration systems have been proposed over time.

In a previous paper (Pastero, 2019), we proposed a new and green method to capture carbon dioxide avoiding the usage of hazardous reagents and the production of harmful compounds. The method involves the application of an aqueous solution of calcium ascorbate (vitamin C) as the only reagent and the precipitation of calcium oxalate as the main reaction product.

The role of the chemical and physical process variables controlling the reaction has been investigated in order to increase significantly and stabilize the reaction yield in terms of CO₂-sequestration capacity. In the present paper, we evaluated the performance of our method quantitatively, referring to two simple experimental setups: the maximum carbon dioxide yield exceeded 60 %, meaning that every 100 mol of carbon dioxide fed to the capturing system, 60 mol are removed and stored into a stable solid phase. This boost in the method’s performance was obtained optimizing the key-parameters of the reaction and increasing the exchange surface.

大气中二氧化碳的增加是一个不懈的上升过程。随着时间的推移，已经提出了许多旨在减少二氧化碳排放以及在各种稳定的隔离系统中捕获的缓解措施。

在上一篇论文（Pastero，2019年）中，我们提出了一种新的绿色方法来捕获二氧化碳，从而避免使用有害试剂和生产有害化合物。该方法包括使用抗坏血酸钙（维生素C）水溶液作为唯一试剂，并沉淀草酸钙作为主要反应产物。

已经研究了化学和物理过程变量控制反应的作用，以便根据螯合CO _2的能力显着增加并稳定反应产率。在本文中，我们参考了两个简单的实验设置，对方法的性能进行了定量评估：最大二氧化碳收率超过60％，这意味着每100摩尔二氧化碳被捕集到捕集系统中，并被存储起来。变成稳定的固相 优化了反应的关键参数并增加了交换表面，从而提高了方法的性能。
