摘要
针对原有测量标准进行微调,选用商品标准溶液稀释、配制成一系列的工作溶液。选择合适的测量条件,用火焰吸收法测定了汽油中铁、铅离子的含量。针对新方法的检出限、准确度、回收率等进行了讨论,确定了新方法的可行性以及测量的最佳条件、测量特性。
In this paper, we reported the fine-tuning work on the flame absorption's existing measurement standard and a new measuring method was employed. A series of working solutions were prepared by diluting the purchased standard solution, and the measuring conditions were selected, to measure the content of iron and lead ions in gasoline. The detection limit, the degree of preciseness, and the rate of recovery were then discussed with the purpose of confirming the feasibility of the new method, and the optimum measuring condition and measurement characteristics were also ascertained. In conclusion, the superiority of the new measuring method was affirmed from the above comparative work.
