紫外光谱法测定甲壳素的脱乙酰化值
UV Specttophotometric Determination of the Degree of Deacetylation of Chitin
【摘要】 用紫外光谱测定甲壳素脱乙酰程度,该法快速简便,重现性好,试样无需特殊处理。
【Abstract】 A UV spectrophotometric method for the determination of the deacetylation de-gree of chitin is described based on the stability of chitosan in 0.001mol/L hydrochloric acid.The method is rapid, simple and the pretreatment of the samples is not necessary.
