MT/T 201-2008 《Determination of chlorine ion in coal mine water》 Related products

This standard specifies a method for the determination of chloride ion content in coal mine water using the silver nitrate (AgNO3) volumetric method. It is suitable for the determination of chloride ion concentration in the range of 5 mg/L to 400 mg/L. Under the condition of adjusting the pH value of the water sample to 7.0 to 8.3, titrate with silver nitrate (AgNO3) solution to generate white silver chloride settling to quantify chloride ions, and calculate the chloride ion content by the Color change at the end point of titration. The required reagents and calibration methods are described in detail.
