摘要
根据《土壤和沉积物石油烃(C_(10)~C_(40))的测定气相色谱法》(HJ 1021—2019),本研究对沉积物中的石油烃(C_(10)~C_(40))开展了实验室内部方法验证。结果表明,石油烃(C_(10)~C_(40))在0~9 300 mg/L内的线性结果良好,相关系数不小于0.999。实验室测定的沉积物石油烃(C_(10)~C_(40))检出限为2.1 mg/kg,相对标准偏差为2.94%~4.01%,加标回收率为91.4%~95.1%,符合标准要求。测定结果表明,实验室具备检测沉积物石油烃(C_(10)~C_(40))的能力。
According to the"Determination of Petroleum Hydrocarbons(C_(10)-C_(40))in Soils and Sediments Gas Chro⁃matography"(HJ 1021-2019),this research carried out laboratory internal method verification on petroleum hydro⁃carbons(C_(10)-C_(40))in sediments.The results show that the linearity of petroleum hydrocarbons(C_(10)-C_(40))in the range of 0~9300 mg/L is good,and the correlation coefficient is not less than 0.999.The detection limit of sediment petro⁃leum hydrocarbons(C_(10)-C_(40))determined by the laboratory is 2.1 mg/kg,the relative standard deviation is 2.94%~4.01%,and the recovery rate of standard addition is 91.4%~95.1%,which meets the requirements of the standard.The measurement results show that the laboratory has the ability to detect petroleum hydrocarbons(C_(10)-C_(40))in sedi⁃ments.
