Methods
Chloride is the most common inorganic anion found in water and wastewater. The Maximum Secondary Contaminant Level for drinking water for chloride is 250 mg/L. Natural sources of salt are the ocean and various salt deposits above and below ground.
Chloride is very corrosive to most metals in systems with elevated pressures and temperatures such as boilers and oil-drilling equipment.
The Mercuric Nitrate Method
References: APHA Standard Methods, 23rd ed., Method 4500-Cl- C-1997. ASTM D 512-04, Chloride Ion in Water, Test Method A. USEPA Methods for Chemical Analysis of Water and Wastes, Method 325.3 (1983).CHEMetrics employs a mercuric nitrate titrant in acid solution with diphenylcarbazone as the end point indicator. Results are expressed as ppm (mg/L) Cl-.
The Ferric Thiocyanate Method
Reference: APHA Standard Methods, 23rd ed., 4500-Cl-E-1997. D. Zall, D. Fisher, M. Garner, “Photometric Determination of Chlorides in Water,” Analytical Chemistry, Vol 28, No. 11, pp. 1665-1668, November 1956. J. O’Brien, “Automatic Analysis of Chlorides in Sewage,“Wastes Engineering, pp. 670-672, December 1962.The Chloride Vacu-vials® test employs the ferric thiocyanate chemistry. Chloride reacts with mercuric thiocyanate to liberate thiocyanate ion. Ferric ion reacts with thiocyanate ion to produce an orange-brown thiocyanate complex in proportion to the chloride concentration. Results are expressed as ppm (mg/L) Cl-.
