Determination of combustion oxidation slow release non dispersed infrared absorption method study on total organic carbon(toc)in soil
The total organic carbon(TOC)content in environmental soil is an important indicator reflecting soil organic pol-lution.This article improves the traditional combustion oxidation non dispersed infrared absorption method for determining TOC by adding a slow-release program to the conventional combustion oxidation non dispersed infrared absorption method for determining the total organic carbon content in different soils.The experimental results show that the standard curve es-tablished by this method has good linearity,and the relative standard deviation of soil samples measured multiple times is small.This method effectively reduces the errors caused by interference components and complex combustion reactions,It has the characteristics of low anti-interference,high precision,good robustness,and good accuracy,and is expected to be applied in the determination of TOC in soil samples.
