Sulfated galactans procedure

Determination of the sulfate content requires the preliminary hydrolysis of galac-tans by the action of 1 M HC1 at 100 °C for 6 h (hydrolysis in 2 M trifluoroacetic acid can also be used for simultaneous determination of monosaccharides and sulfate). Quantitative estimation of sulfate in hydrolyzates can be performed by many methods known from inorganic analytical chemistry,218,219 but the most popular procedure in the case of galactans is turbidimetry of stabilized suspensions of BaSO.4. It was suggested in the early 1960s220 and is widely used at present in the slightly modified form.221... [Pg.132]
