超声洗脱-离子选择电极法测定工作场所空气中氟化物方法的改进

Improvement of determination of fluoride in workplace air by ultrasonic elution ion selective electrode method

对工作场所空气中氟及其化合物的测定方法进行了研究,对现行GBZ/T 160.36标准中试样洗脱方法进行了改进,提出用超声振荡洗脱处理样品,用离子选择电极法测定样品中氟化物的含量。该法操作简单、准确快捷,测定结果令人满意。

the determination of fluorine and its compounds in the air of the workplace was studied.The method ofsample elution in the current GBZ/T 160.36 standard was improved.The sample was treated by ultrasonic oscillation elution,and the content of fluoride in the sample was determined by ion selective electrode method.The method is simple, accurateand quick, and the resuh is satisfactory.
