Sulphate (SO\u2084\u00b2-) is a naturally occurring anion in many bodies of water and mainly comes from the weathering of sulphate-containing minerals such as gypsum (CaSO\u2084) and anhydrite. In industrial processes, sulphate also enters the water through wastewater, cooling towers and chemical production processes. <\/p>\n
The limit value for sulphate in drinking water is 250 mg\/l<\/strong> (Drinking Water Ordinance). Elevated sulphate concentrations can have a deleterious effect and impair the taste of the water. Sulphate monitoring is particularly important in industry, as high concentrations can lead to corrosion of concrete structures and pipelines. <\/p>\n This test set with a resolution of 10 mg\/l SO\u2084\u00b2- per drop is ideal for monitoring drinking water, process water and industrial applications in the medium concentration range.<\/p>\n The CALDUR\u00ae Sulfate 10 mg test kit works according to the principle of precipitation titration. The water sample is first passed through an ion exchanger to remove interfering ions. A reagent is then added and titrated drop by drop until a color change indicates the end point. <\/p>\n Measuring principle:<\/strong> Barium ions from the titration solution react with sulphate ions and form poorly soluble barium sulphate. The end point is indicated by a Reagent. Each drop corresponds to 10 mg\/l SO\u2084\u00b2-. <\/p>\n Calculation:<\/strong> Number of drops \u00d7 10 = sulphate concentration in mg\/l.<\/p>\n Efficient on-site determination without laboratory equipment<\/p>\n<\/li>\n Precise measurement in the medium concentration range<\/p>\n<\/li>\n Economical for regular monitoring<\/p>\n<\/li>\n Reliable and reproducible results<\/p>\n<\/li>\n Precise results even with complex water matrices<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Sulfate 10 mg test set – Titrimetric What is sulfate measured for?
