How can copper ion electrodes and potassium ion electrodes improve accuracy and resolution when measuring copper ions and potassium ions? Please offer more suggestions. Thank you very much. Additional info: It is used by power plants to measure Cu ions and K ions in water. This post was last edited by lifanwang on 2009-3-14 at 20:47.]
Could you specify what analysis project it is in that industry? Heavy metals in water quality? How about you check the index post with the analysis materials I gave you? http://bbs.hcbbs.com/thread-400293-1-1.html
Hasn’t anyone used copper ion electrodes and potassium ion electrodes? If you have, please share your thoughts
Crystal membrane Cu ion-selective electrode: Main functions and features. It has a robust structure, is resistant to organic solvents, and is easy to clean. The electrode surface can be updated using polishing components, resulting in a long service life. Key technical parameters: Temperature range: 0...80℃; Measurement range: 1×10－8...0.1 mol/L; pH range: 2...12. Application areas: Complex titration, such as total hardness in water, EDTA calibration, etc. A potassium electrode is a PVC membrane ion-selective electrode made of chemically active materials, used to measure the concentration of potassium ions in solutions. Technical parameters: 1. Measurement range: 10-1 to 10-5 (M). 2. pH range: 4 to 11 (pH). 3. Percent theoretical slope: (PTS) ≥ 93% (25°C). 4. Operating temperature: 10 to 35°C. 5. Response time: ≤ 2 minutes (25°C). 6. Internal resistance: ≤ 50 KΩ (25°C). Last edited by lifanwang on 2009-3-14 at 20:41.]
