I did a BET analysis of an activated carbon that I prepared but the experiment took over three days to finally give just the first two points. Knowing that the initial mass analyzed was 100 mg.
Please, could someone suggest me a solution that will allow me to reduce this time.
thank you
Good evening,
Thank you very much for your clarification. I will review all the points that you have quoted
My respectful greetings
1. The BET method (mainly based on nitrogen adsorbed at 77 K), does not provide a realistic assessment of the surface area of an activated carbon. https://doc.rero.ch/record/9137/files/Stoeckli_F._-_On_the_determination_of_surface_areas_20080416.pdf
2. Information about the structure of activated carbons can be obtained by the adsorption characteristics of different adsorbates, such as methylene blue and iodine. Adsorption experiments of these molecules are easy and habitually done to characterize activated carbons with the purpose of obtaining information on the adsorption capacity of the materials. http://www.scielo.br/pdf/qn/v34n3/20.pdf
good morning ,
Thank you very much for all your answers.
For analysis I use the Autosorb - Quantachrome Instrument
good day to all
