This solvent is often used similarly to dichloromethane.
What is a common first step before performing liquid-liquid extraction?
Consider what could alter the results if not removed.
True or False: Dichloromethane is considered a safe solvent for disposal in water systems.
Remember the risks associated with hazardous materials.
Design a filtration system suitable for removing suspended solids from wastewater before it undergoes liquid-liquid extraction. Consider the scale of operations and environmental factors.
Think about the balance between efficiency and the level of purification needed.
Evaluate the trade-offs between efficacy and environmental safety when using dichloromethane for extractions. What alternatives could be considered?
