Copper is naturally present in the earth’s crust and in seawater. Copper-containing fungicides are used to control biological growth in water supplies. The Maximum Contaminant Level Goal for copper is 1.3 mg/L in drinking water.
The measurement of copper is an important means of monitoring the corrosion of condensate systems and heat exchangers.
The Bathocuproine Method
Reference: APHA Standard Methods, 22nd ed., Method 3500-Cu C - 1999.
CHEMetrics’ test kits employ the bathocuproine reagent. Bathocuproine disulfonate forms an orangecolored chelate with copper. The method measures total soluble copper as ppm (mg/L) Cu. The test kits are applicable for analysis of drinking water, surface waters, groundwater, wastewater and seawater.
Range: 0-1 & 1-10 ppm
MDL: 0.05 ppm
Method: Bathocuproine
Kit comes in a plastic case and contains everything needed to perform 30 tests: Refill, Low and High Range Comparators, 25 mL sample cup, and instructions.
