A fully executable, safety-critical standard operating procedure for hydrothermal synthesis of carbon dots using citric acid–urea, strictly constrained to ≤180 °C reaction temperature and mandating 0.22 μm filtration as the final, non-omissible purification step.

Generate a lab-ready, step-by-step Standard Operating Procedure (SOP) for hydrothermal synthesis of carbon dots (CDs) from citric acid and urea — with zero tolerance for temperature excursions above 180 °C, and with 0.22 μm membrane filtration explicitly required as the final, mandatory purification and quality-control step.
