A mini review of recent advances in environmentally friendly microplastic removal technologies in water systems.

The current increase in microplastic (MP) occurrence worldwide is predicted to cause severe environmental crises in the future. Therefore, it is imperative to develop innovative MP removal technologies that can effectively mitigate MP emissions in any given scenario. This review discusses recent environmentally friendly advances in MP removal technologies that aim to overcome the limitations of current technologies, prevent secondary pollution, and utilize low energy.

Correlation of CO absorption performance and electrical properties in a tri-ethanolamine aqueous solution compared to mono- and di-ethanolamine systems.

The study investigates the correlation of CO absorption performance and electrical properties in a tri-ethanolamine (TEA) aqueous solution compared to the mono-ethanolamine (MEA) and di-ethanolamine (DEA) systems. While the absorption rate of the MEA and DEA systems varies with amine concentration, and the maximum rate is observed at 30.0 and 50.

Carbon dioxide capture capacity of sodium hydroxide aqueous solution.

The present paper investigates the various features of NaOH aqueous solution when applied as an absorbent to capture carbon dioxide (CO(2)) emitted with relatively high concentration in the flue gas. The overall CO(2) absorption reaction was carried out according to consecutive reaction steps that are generated in the order of Na(2)CO(3) and NaHCO(3). The reaction rate and capture efficiency were strongly dependent on the NaOH concentration in the Na(2)CO(3) production range, but were constant in the NaHCO(3) production step, irrespective of the NaOH concentration.
