Radiocarbon dating is a tool for age determination of a carbon sample. During the time, synthesis benzene method is used for age determination mentioned. By this method it could be analyzed one sample per day only with high material cost. Lately, it has been developed a new method, namely CO2 absorption method. The latest method is often called as direct counting CO2, because radioisotope of 14C in CO2 is counted directly and converted to age. The aim of the development and the use of the method are supporting some research in isotope hydrology, oceanography, climatology, geology, and archeology by faster, economic and practice. The result of 14C analyses for the same sample using the CO2 absorption when compared to the synthesis benzene method is relatively equal.

Radioactivity Monitoring

ABSTRACTThe CO2 absorption and liquid scintillation counting (LSC) are methods used in radioactivity monitoring programs of nuclear facilities for 14C measurements due to high number of samples and relatively high expected level of 14C concentration. The paper describes the chemical sample preparation applied to a quality control material (IAEA-C3 Cellulose), in order to evaluate the reproducibility of CO2 absorption method for this type of material. Consequently, in the experiments we used two home-made scintillation cocktails, containing two amines, 2-methoxyethylamine (MEA) and 3-methoxypropyl amine (MPA), which detained CO2 as carbamates. Due to the fact that the material used in the dedicated experiments is cellulose (contained in all vegetable materials), the method can be considered as appropriate for 14C determination from biological and vegetable materials.

Factors Influencing

Anthropogenic CO2 emissions has led to global climate change and widely contributed to global warming since its concentration has been increasing over time. It has attracted vast attention worldwide. Currently, the different CO2 capture technologies available include absorption, solid adsorption and membrane separation. Chemical absorption technology is regarded as the most mature technology and is commercially used in the industry. However, the key challenge is to find the most efficient solvent in capturing CO2. This paper reviews several types of CO2 capture technologies and the various factors influencing the CO2 absorption process, resulting in the development of a novel solvent for CO2 capture.
