What Is the Importance of Manganese in Lithium-Ion Batteries?
Manganese is one of the most important components in lithium-ion batteries due to its low cost and availability. The performance of these batteries strongly depends on cathode materials, and Li-rich Mn-based materials have attracted more attention recently because of their high capacity and voltage.
Why Is It Necessary to Determine Manganese Content in Water?
Exposure to excess manganese can be harmful to both flora and fauna, and it affects the central nervous system, causing symptoms similar to those of Parkinson's disease. The permissible limit of Mn in drinking water according to the EPA is 0.05 mg/L, and the WHO permissible limit for releasing manganese into the environment is 0.4 mg/L.
How to Determine Manganese Content in Battery Wastewater Spectroscopically?
Manganese content in drinking water and battery wastewater can be determined using the formaldoxime method with a UV Vis spectrophotometer. The formaldoxime method involves the reaction of formaldoxime with ammonium hydroxide in an alkaline solution to produce an intense orange-red colored complex. This method is applicable to determine the manganese content in the range of 0.01-5 mg/L.
