| 摘 要： | 用以邻—甲酚酞络合剂为显色剂的分光光度法测定了十五种常用饲料(包括牛奶和鸡粪)样品中的钙含量,并与用高锰酸钾法测定的钙值进行了比较。结果表明,用邻—甲酚酞比色法测定钙含量比用高锰酸钾法具有快速、灵敏、简便的特点。建议用邻—甲酚酞比色法作为营养分析中测定钙含量的常规方法。

| Abstract: | 15 feeds were determined for their calcium contents by O-cresolphthalein complexone colorimetry (OCC).Calcium recoveries from com,cotton seed meal,soybean meal and wheat bran and from rice straw,alfalfa,soybean flour,silage,fish meal,bone meal,were 83%~88%.and 96%-104% respectively.Compared with permanganic potassium volumetric method,OCC had similar accuracy,but easier and faster.OCC method could be available for feed calcium determination in routine laboratory. |
