摘要
研究配制了复合硬度指示剂。试验证明 ,用此指示剂及比色卡可简单迅速测定在 0～ 0 .0 5mmol L范围内水样的硬度。经使用效果良好 。
The water hardness indicator has been studied. The experimental results reveal that it is very easy and quick to determinate the hardness of water sample with the water hardness indicator and colourimetric card.The hardness range is 0～0.05 mmol/L. The indicator has been used in steam boiler's water supply and circulating cooling water systems including making of soft water, demineralized water and pure water .Good results have been achieved.
