Quantitative analysis of organic acids after separation by column chromatography

2 Quantitative analysis of organic acids after separation by column chromatography [Pg.544]

Organic acids are absorbed from an acidified aqueous solution by being passed through a chromatographic column of silica gel. After elution with a chloroform/butanol mixture, titration is carried out in the eluate itself with methanolic sodium hydroxide solution. This method is only recommended for dissolved organic acids after preliminary filtration of the water sample, where necessary. [Pg.544]
