• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Chemical Composition and Properties: Potassium carbonate is a potassium salt, specifically the dipotassium salt of carbonic acid. It is categorized as a carbonate salt and a potassium salt. Potassium carbonate exhibits properties such as serving as a catalyst, fertilizer, and flame retardant.
• Thermochemical Energy Storage: Potassium carbonate has garnered attention as a potential candidate for thermochemical energy storage. However, its reaction kinetics are relatively slow, posing challenges for efficient energy storage applications.
• Catalytic Torrefaction: The impregnation of wood powder with potassium carbonate (K2CO3) has been demonstrated as a pretreatment method for catalytic torrefaction. This process catalyzes the thermal degradation of wood powder, enhancing its suitability for energy utilization.
• Volatility Reduction in Herbicides: Potassium carbonate is employed as a volatility-reducing agent (VRA) in herbicide formulations, particularly to decrease the volatility of dicamba. By increasing the pH of the spray mixture, potassium carbonate helps mitigate dicamba volatility, contributing to improved herbicide efficacy and environmental safety.
• Alternative Activator in Biochar Production: Potassium carbonate, along with other potassium salts such as KHCO3 and K2C2O4, is proposed as an alternative activator for producing activated biochar with high porosity and minimal environmental impact. Activated biochar prepared using potassium carbonate finds applications in various fields, including supercapacitors, lithium-ion batteries, electrochemical hydrogen storage, and more.
• Historical and Traditional Uses: Potassium carbonate has been historically recovered from wood ashes and cocoa pod husk ash. The ashes, rich in potash, are leached to obtain an alkaline solution containing potassium hydroxide and potassium carbonate. This solution has been traditionally utilized in local soap production. The recovery of potassium carbonate from wood ashes dates back to early processes, with cocoa pod husk being highlighted as an excellent source of potassium salts.
