Investigation of manufactured carbon in the environment
The stability, strength, and good electrical conductivity of graphite raise interest in designing materials with graphite-like structures. Biochar and carbon nanotubes (CNTs) are two commonly used materials with a graphite-like structure. Methods for their quantification in environmental samples are needed to assess exposure risk and perform full life cycle assessments. Use of biochar in agriculture and carbon sequestration raises the need for its quantification in soil. Difficulty lies in the presence of natural soil organic matter. In order to differentiate the two species, thermogravimetric ...
