Subject:
carbon; monitoring; oxidation; sediments; soil profiles; soil treatment; topsoil
Abstract:
... The chemo-thermal oxidation method at 375°C (CTO-375) has been widely used to quantify black carbon (BC) in sediments. In the present study, CTO-375 was tested and adapted for application to soil, accounting for some matrix specific properties like high organic carbon (≤39%) and carbonate (≤37%) content. Average recoveries of standard reference material SRM-2975 ranged from 25 to 86% for nine repr ...
