摘要
Abstract
In order to prepare copper sodium chlorophyllin from Spirulina and investigate its stability,chlorophyll-rich paste was extracted from Spirulina using organic solvent.Sodium copper chlorophyllin was then synthesized from this paste through saponification,acidification,and copper substitution processes.UV absorption spectroscopy was used in evaluating the stability of the prepared sodium copper chlorophyllin under various conditions,including different temperatures,light exposures,pH levels,and in the presence of oxidizing and reducing agents.Results showed that the sodium copper chlorophyllin prepared from Spirulina was a dark green,highly water-soluble substance with a metallic luster.It exhibited good thermal stability,remaining stable at temperatures up to 80℃.The compound was stable under neutral and alkaline conditions but degraded under acidic conditions.The compound was resistant to reducing agents,sensitive to high concentrations of oxidizing agents,and showed poor light stability.关键词
