摘要
对水中碳酸盐硬度与非碳酸盐硬度的测定方法作了探讨,试验结果表明,水样于电炉上加热煮沸6 min后,碳酸盐硬度可基本消除,冷却后测定的硬度即为非碳酸盐硬度,从总硬度中减去非碳酸盐硬度,即为水样的碳酸盐硬度。
Carbonate hardness and non- carbonate hardness of water was measured in this study. The result showed that after boiled for 6 min, carbonate hardness could be removed and total hardness determined after cooling was non - carbonated hardness, Carbonated hardness equals to total hardness minus non -carbonated hardness.
