用中性载体钙电极测定肉中的钙含量是一种简便、快速、灵敏、准确的方法。本法的回收率范围在99～105％,标准偏差为±0.027,变异系数为2.7％。本法与原子吸收法对比试验,两者无显著性差异(P>0.05)。实验【仪器与试剂】 1.ETH—1001PVC中性载体钙离子选择性电极(江苏电分析仪器厂)。
Determination of calcium in the meat using a neutral carrier calcium electrode is a simple, rapid, sensitive and accurate method. The recovery rate of this law ranged from 99 to 105% with a standard deviation of ± 0.027 and a coefficient of variation of 2.7%. The law and atomic absorption method of comparative test, no significant difference between the two (P> 0.05).
