本文通过测定加入不同量的标准试剂时体系的电位,建立方程组,用微机对方程组进行求解,即可计算出 Fe~(2+)和 Fe~(3+)各自的含量。
In this paper, we determined the potential of Fe 2+ and Fe 3+ by measuring the potential of the system with different amounts of standard reagents, and then established the system of equations by using computer to solve the equations.
