蜂蜜不经消化 ,用 4.0 %硝酸溶液溶解浸泡 ,直接喷入空气 -乙炔火焰中测定吸光度 ,以标准曲线定量 ,方法的平均回收率为 99.6% ,其合并变异系数为 3.5 7%。与国标法比较试验的测定结果 ,经统计学处理差异无显著性
The honey was digested and dissolved in 4.0% nitric acid solution. The absorbance was measured by direct injection into the air-acetylene flame and quantified by a standard curve. The average recoveries of the method were 99.6% with a combined coefficient of variation of 3.57%. Compared with the national standard test results of the test, the difference was not statistically significant
