摘要:
测量循环冷却水中钾离子质量浓度，以此来计算循环水浓缩倍数、调节新鲜水的加入量是工厂维持热平衡的重要手段.为了比较、优化各种测量钾离子质量浓度的原子光谱方法，配制钾标准溶液，选择合适的仪器条件，分别用火焰原子吸收、火焰原子发射、电感耦合等离子体原子发射测定了循环冷却水中的钾离子质量浓度.针对不同测量方法的线性范围、检出限、准确度等进行了对比讨论，确定了3种方法的最佳测量条件、各自的测量特性以及测量范围，比较了3种方法的优劣.结果表明3种方法都能定量测量出钾离子质量浓度：其中电感耦合等离子体原子发射有较佳的测量效果，但是价格昂贵，不利于例行分析；两种火焰原子方法测量性能接近，火焰原子发射硬件条件要求低，是测量碱金属的较佳方法.不同方法的比较为工厂根据实际条件进行选择提供了依据.
Abstract:
Measuring the potassium ion concentration in the circulating cooling water is an important method to maintain the thermal balance in factory because it is the basis for calculating the concentration ratio of circulating water and adjusting the amount of fresh water. The potassium standard solution was prepared to compare and optimize the atomic spectrum methods for measuring the potassium ion concentration; the appropriate instrument conditions were chosen and the potassium ion concentration was measured by three methods including flame atomic absorption, flame atomic emission and inductively\|coupled plasma atomic emission. The optimum measuring conditions, the measurement characteristics and range of the above three methods were determined based on the comparison of linear range, detection limit and accuracy. The advantages and disadvantages of these three methods were also compared. The results show that the three methods can be used to quantitatively measure the potassium ion concentration. The inductively\|coupled plasma atomic emission has better measurement effect, but the cost is large and the timeliness is not optimal. The measurement characteristics of two flame atomic measurement methods are close. The flame atomic emission method has low hardware requirement, and is the better way for measuring the alkali metal concentration. The comparison of three methods provides reference to the actual selection in factory.
