Abstract
Chitosans were quantified with ninhydrin, a reagent normally used for recognizing and quantifying amino groups. The reaction was time dependent and there was no effect when different acids were added to the mixture. This method was used to determine the percentage of free amino groups in chitosans of different origins.
摘要
壳聚糖用茚三酮进行定量，茚三酮是一种通常用于识别和定量氨基的试剂。该反应具有时间依赖性，向混合物中添加不同的酸时没有影响。该方法用于测定不同来源壳聚糖中游离氨基的百分比。
