Method PV2115

Oxalic Acid


This method is for the collection and analysis of oxalic acid from workplace air.  The sample is collected on a glass fiber filter.  After sample collection the extracted with 10mLs of a misture of 0.028M sodium hydroxide (NaOH) and analyzed by ion chromatography (IC). 

NOTE:  This is a partically validated method.
