COMPARISON BETWEEN UV SPECTROPHOTOMETRY AND ANION EXCHANGE CHROMATOGRAPHY TECHNIQUES FOR QUANTIFICATION OF HEXENURONIC ACID (HEXA) IN UNBLEACHED KRAFT PULPS OF EUCALYPTUS GLOBULUS
Two different methodologies were optimized for hexenuronic acid (HexA) quantification in E. globulus kraft pulps. In one, pulps were hydrolyzed with mercuric chloride/sodium acetate and quantified by ultraviolet spectrophotometry (UV technique); in the other one, the hydrolysis was performed with su...
