摘要
用原子吸收分光光度计测定了硬脂酸钙中的钙,确定了仪器的最佳工作条件。测定结果表明方法线性良好,r=0.9999,加标回收率为98.9%～101.7%,相对标准偏差0.37%;测定结果与行业标准一致。操作简单易行,可以满足实际工作需要,并可对同一样品溶液进行其他元素的测定,更适合于成批样品的例行分析。
Atomic absorption spectrophotometer is used to determine calcium in calcium stearate,the best working conditions are fixed.Test results show that the method is good in linearity,r=0.999 9,recovery of standard addition is 98.9%～101.7%,relative standard deviation is 0.37%;test results are of the same as the industry standard.The operation is simple and easy,which can meet the practical need,and can also be used to determine other elements in the same sample solution.It is more suitable for routine analysis for samples in batches.
