GB/T 11896-1989 《Water quality--Determination of chloride--Silver nitrate titration method》 Related products
This standard applies to the determination of chlorides concentration in natural water, brackish water, seawater and pretreated domestic sewage or industrial wastewater. Titrimetric method of silver nitrate (AgNO3), using potassium chromate as an indicator, titration of chlorides to the end point in the pH range of 6.510.5. Applicable to water samples with chlorides concentration between 10,500 mg/L, samples above this range need to be diluted and determined. This standard is widely used in water quality analysis and environment monitoring.
