活性炭による空気中のアルキル鉛のけい光X線分析

抄録

It has been found that gasoline vapor contained alkyl lead can be absorbed on active carbon and amount of lead content quantitatively analysed by X-ray fluorescent method.
For briqueting carbon powder, stealic acid was suitable binder, and the employed mixing ratio of carbon and binder was 3:2.
The results were quite consistent with calibration curve which was obtained by impregnation method of lead standard solution over the range from 0.1 mg to 0.5 mg Pb/3 g carbon.
