Determination of TOC in Crystalline Salt from Wastewater Zero Discharge Process by Total Organic Carbon Analyzer

Abstract

The methods for testing total organic carbon in crystalline salt from wastewater by Multi N/C 2100S instrument were introduced. Salt crystals from wastewater zero discharge process, and under the condition of quantitative dilution of the solution to 2.35% salt content, the feasibility of using Multi N/C 2100S total organic carbon analyzer to accurately determine the content of organic carbon in high salt brine was studied. The accuracy and precision of the TOC method for high salt water samples were analyzed. The results showed that the total organic carbon analyzer could be used for the detection of high salt water and the characterization of organic compounds in crystalline salt with zero discharge from waste water.
