Abstract

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.

Key words： hardness indicator; colourimetric card; determination of hardness
