摘　　要：确定了邻菲罗啉分光光度法测定单宁酸含量的最佳条件,测定结果表明板栗刺壳、核桃青皮及葡萄皮中的单宁酸含量分别为6.55%、4.06%和2.10%。希望能够为这些废弃物的回收利用提供数据支持和理论依据。The optimal conditions of phenanthroline spectrophotometry method to detect the content of tannin were determined. The results showed that the tannin content in chestnut shell, walnut seedcases and grape husk was 6.55%, 4.06% and 2.10% respectively. We hope that this study can provide a theoretical basis for recycling of these wastes.
