The thermal decomposition behavior of sodium arsenite (SA) was greatly affected by carbonized beta-cyclodextrin (CD), possessing the releases of four forms of gaseous arsenic molecules according to gas chromatography coupled to time-of-flight mass spectrometry with programmed temperature operation. Also, the decomposition temperature of beta-CD was lowered in the presence of SA.
