Copper in Water
Publication No. 11960
The amount of copper in a water sample will be found by using the TesTab® color comparison method.
Copper is a reddish colored metal that is found in air, water, soil and rocks. It may be present in water from sewage or industrial waste and from copper plumbing and fixtures. Copper is sometimes added to reservoirs and ponds to control the amount of aquatic vegetation. Even though copper is essential in small amounts to the human body, excessive amounts can result in nausea, stomach cramps and even liver damage. If concentrations of copper are above 1 part per million, drinking water may taste bitter. In general, the amount of copper found in drinking water is below 0.03 parts per million, but it may reach up to 0.6 parts per million in certain places.
Copper HR TesTabs®, 15
Copper HR TesTabs® contain chemicals that may irritate skin or be harmful if swallowed. The TesTab reagents used in this kit were designed with safety in mind. The single-use, foil-packaged TesTabs are easy to dispense. Store TesTabs in a cool, dry place and only open when ready to use the tablet. A single tablet, either alone or reacted with a sample, is a very low safety hazard; however, TesTabs should not be ingested. Wear chemical splash goggles and chemical-resistant gloves. Wash hands thoroughly with soap and water before leaving the laboratory. Please review current Safety Data Sheets for additional safety, handling and disposal information.
Please consult your current Flinn Scientific Catalog/Reference Manual for general guidelines and specific procedures, and review all federal, state and local regulations that may apply, before proceeding. In the field, reacted samples may be poured into a container for later treatment. Reacted samples may be flushed down the drain with plenty of water according to Flinn Suggested Disposal Method #26b.
