ICP-AES有机溶剂稀释法测定煤焦油中镍、铁、钒的含量

摘要

采用有机溶剂稀释法,即用适量的稀释剂溶解样品,然后用电感耦合等离子发射光谱仪(ICP-AES)测定煤焦油中镍、铁、钒金属离子的含量.方法具有快速、准确,易于操作的特点,且在减少样品的分析误差的同时提高了样品的测量精度.故本方法应用于测定煤焦油中的镍、铁、钒金属离子的含量是可行的.%This paper uses organic solvent dilution method, which is just the right amount of thinner, dissolve the sample, and then using inductively coupled plasma emission spectrometer (ICP-AES) determination of nickel, iron, vanadium in coal tar content of metal ions. This method is fast and accurate, and the characteristics of easy operation, and to reduce the analytical error of samples at the same time improve the measurement precision of the sample. This method is applied to the determination of nickel, iron, vanadium in coal tar content of metal ions is feasible.
