description The present invention relates to a quantitative analysis method of lead or arsenic comprising the steps of: preparing talcum powder, which is the standard sample of blank powder; preparing two or more standard samples of powder for each concentration, which have different concentrations, by adding lead or arsenic to the talcum powder; selecting an interference element having an energy value corresponding to the range of the detected energy value of lead or arsenic among element detected by irradiating a sample for analysis with x-rays; correcting the detected energy peak of lead or arsenic among energy peaks, which have been detected by irradiating the standard samples of powder for each concentration with x-rays in the step of selecting the interference element, from the overlapping detected energy peak of the interference element using a deconvolution method; drawing a standard calibration line by conducting the deconvolution method after irradiating the prepared standard samples for each concentration with x-rays; and detecting an energy peak by irradiating the sample for analysis with x-rays and measuring the concentration of lead or arsenic in the sample for analysis from the detected energy peak value according to a standard calibration method depending on the drawn standard calibration line. 본 발명은 블랭크 파우더 표준 시료인 활석 파우더를 준비하는 단계; 활석 파우더에 납 또는 비소를 첨가하여 농도가 상이한 둘 이상의 농도별 파우더 표준 시료를 준비하는 단계; 분석 시료에 X선을 조사하여 검출된 윈소들 중 해당 에너지값이 납 또는 비소의 검출 에너지값 범위에 해당되는 간섭 원소를 선정하는 단계; 상기 간섭 원소를 선정하는 단계에서 농도별 파우더 표준 시료에 X선을 조사하여 검출된 에너지 피크들 중에서, 납 또는 비소의 검출 에너지 피크를 중첩되는 간섭 원소의 검출된 에너지 피크로부터 보정하는 디컨볼루션 (deconvolution) 단계; 준비된 농도별 파우더 표준 시료들에 대하여 각각 X선을 조사한 후 상기 디컨볼루션 단계를 실시하여 표준 검량선을 작성하는 단계; 및 분석 시료에 X선을 조사하여 에너지 피크를 검출한 후, 검출된 에너지 피크값을 작성된 표준 검량선에 의하여 표준검량법에 따라 분석 시료의 납 또는 비소의 농도를 측정하는 단계;를 포함하는 납 또는 비소의 정량 분석방법에 관한 것이다.
