摘要
利用超声波辅助,测定了白炭黑中的氟。本法绝对误差在0.08~0.19之间,相对标准偏差RSD=0.404%,加标回收率在98.60%~101.80%,检测结果良好,方法简单可靠。
Fluorine in silica was determined by using ultrasonic aid.The absolute error of this method is between 0.08 and 0.19,and the relative standard deviation RSD is 0.404%,The recovery of standard addition is 98.60%-101.80%,and good detection results are obtained.The method is simple and reliable.
