【摘要】：樣品經(jīng)硝酸-過氧化氫微波消解后,采用可拆卸式直接注入高效霧化器-電感耦合等離子體原子發(fā)射光譜法測(cè)定船用燃料油中釩、鋁、鈣、鋅、鎳、銅等26種微量元素的含量,通過多譜線擬合校正法(MSF)校正了Cu對(duì)P 213.617nm和P 214.914nm所產(chǎn)生的光譜干擾。26種元素的線性范圍在10.0mg·L~(-1)內(nèi),檢出限(3s)為0.001~0.087mg·L~(-1)。加標(biāo)回收率在92.1%~106%之間,測(cè)定值的相對(duì)標(biāo)準(zhǔn)偏差(n=7)在0.46%~2.7%之間。采用此方法對(duì)船用燃料油標(biāo)準(zhǔn)物質(zhì)中Fe、Ni、V、S進(jìn)行測(cè)定,測(cè)定值與參考值一致。
[Abstract]:After microwave digestion with nitric acid and hydrogen peroxide, 26 trace elements such as vanadium, aluminum, calcium, zinc, nickel and copper in marine fuel oil were determined by detachable direct injection nebulizer and inductively coupled plasma atomic emission spectrometry. The linear range of the spectral interference between Cu and P213.617nm and P214.914nm was 10.0mg 路L ~ (-1), and the detection limit was 0.001n / L 0.087mg 路L ~ (-1) 路L ~ (-1). The recovery of Cu was between 92.1g 路L ~ (-1) and 10.0 mg 路L ~ (-1) 路L ~ (-1). The relative standard deviation of the measured value is between 0.46% and 2.7%. This method is used for the determination of Fetin NiNiVN S in the standard material of marine fuel oil, and the measured value is in agreement with the reference value.
