The decomposition is highly exothermic and the resulting smoke is very dangerous. Since the biggest hazard comes from the volatile and soluble heavy metal compounds, it's best to convert them into insoluble compounds, which are less toxic. The resulting block can also be covered in another layer of cement, to reduce the diffusion of the heavy metals. Mineral acids and bases should be neutralized to pH5.5 to 9 range before disposal, following approved procedures. Care must be taken to avoid excess heating with strong bases. ALWAYS CHECK THE LOCAL LAWS BEFORE DISPOSING OF ANY REAGENT! For each gram of barium salt, add 15 mL of 10% sodium sulfate solution. Unless the concrete is damaged, broken or dissolved in acid, the heavy metal ions will not be released. WebPick up and arrange disposal without creating dust. Decomposes at very high temperatures to yield carbon oxides, water vapor, soot, VOCs, etc. The best disposal option is to find a drug take back location, which may be found in retail, hospital, or clinic pharmacies; and/or law enforcement facilities. Organic salts, such as acetates and oxalates can be pyrolyzed to carbonates and water vapors. EXALGO. You probably dont even need to filter it once it has reacted with the sodium bicarbonate, just pour it away. The information posted in this article is merely a collection of observations from various amateur chemists and is NOT meant for professionally disposing large amounts of chemicals and should NOT be used as a guideline on neutralizing reagents. Small quantities. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid.
