## Abstract **Summary:** A simple spectrophotometric method is proposed for determining deacetylation degrees (__DD__) of chitinous materials using phosphoric acid as the UV‐transparent solvent system. Calibrating by the extinction coefficients (__A__~210~) of D‐glucosamine and __N__‐acetyl‐D‐gluco

Glyoxyhc acid gives a yellow 1:l complex, [Fe-CHOC00]2+ with iron(II1). The dissociation constant, measured by two spectrophotometric methods, is K = 9.7 + 1 mol 1-l. Oxalic acid gives two complexes with iron(II1) which absorb in the same range around 400 nm. With appropriate precautions and correct
A method for the determination of N-acetylmuramic acid in both synthetic and naturally occurring complex molecules is presented. The hydrolysis of the sample and photometric determination are performed in one step.
A simple, rapid, and accurate spectrophotometric flow-injection method was developed for the determination of sorbic acid in wines based on the oxidation of sorbic acid with K 2 Cr 2 O 7 /H 2 SO 4 at 100ЊC, followed by reaction of the resulting malonaldehyde with thiobarbituric acid, also at 100ЊC,
