FAAS-标准加入法测定浴盐类化妆品的铅

Application of Standard Addition Method for Determination of Lead in Bath Salt

目的:在不分离样品溶液基础上,通过简化样品处理,找出更便捷、准确的检测方法。方法:使用标准加入法和MIBK萃取后标准曲线法测定浴盐样品的铅,比较两种方法消除干扰的效果。结果:使用标准加入法有效解决了各种消解方法所不能达到的除盐效果并且操作简便,结果的相对标准偏差<2%,回收率在98.5%～104.7%。

Object： To find out a detection method more secure,convenient,accurate through simplified sample processing without separating sample solution.Method ： Compared the two methods for the determination of bath salt samples of lead through using the standard addition method and standard curve method after MIBK extraction.Conclusion： The standard addition method is effective for chemical analysis of bath salt.The relative standard deviation of the results is less than 2 % and the recovery rate is between 98.5 % to 104.7 %.
