초록

본 연구는 인산염 인 농도 측정과 관련하여 숙련도에 의해서 정도관리의 지표가 어떻게 개선되는지를 조사하였다. 아울러 분석기기의 종류에 따른 측정값의 차이가 있는지 함께 비교하였다. 분석자의 숙련도가 분석결과에 미치는 영향을 알아보기 위해 3인의 실험자가 2종의 분석기기를 사용하여 수질오염공정시험기준에 따라 인산염 인을 7회에 걸쳐서 방법검출한계와 정량한계를 측정하였으며, 실험결과 5회 이상 반복실험하면 정도관리지표를 만족하였다. 인산염 인의 정량한계는 0.02 mg/L로 계산되었으며, 분석기기가 다른 경우 정량한계 부근의 시료에 대한 흡광도와 농도가 통계적으로 유의미하게 차이가 있음을 확인하였다.

This study investigated how the indicators of quality control are improved by proficiency in the measurement of phosphate concentration. In addition, analysis equipments were to be compared to see if there were any differences in measurements depending on the type of analysis device. In order to find out the effect of the proficiency of the analyst on the analysis results, three analysts measured phosphate concentration seven times in accordance with the Korean water pollution test standards, and met the quality control indices if repeated more than five times. The limit of quantification for phosphate was calculated at 0.02 mg/L. If the analysis devices are different, the absorbance and concentration of the samples near the limit of quantification are statistically significant difference.
